About Dr. Gyu Gang,
Heart Valve Surgeon

"I've been suffering from a chronic mitral valve prolapse throughout the course of my life and knew that eventually my mitral valve would have to be repaired or replaced. So, when it was determined earlier this year that the time had come for me to have my valve fixed, I set out to find the best surgeon in the area.

My search led me to Dr. Gyu Gang at Central DuPage Hospital in Winfield, Illinois. Central DuPage Hospital is an affiliate of Northwestern University Medical Center. The first thing that caught my attention was Dr. Gang's educational background and experience which was in itself very impressive. Next thing that stood out to me was the positive and near perfect reviews by his patients. I called for an appointment and the staff could not have been more helpful or supportive in setting up the appointment.

When I finally met Dr. Gang, he was more impressive in person. He came in wearing his scrubs and was very humble. He had already reviewed all my tests and medical history and presented his plan for my surgery. He spoke very highly of his team and staff; he was very positive about the outcome of my surgery and his ability as a surgeon. Probably the most impressive thing about Dr. Gang was that he took the time to listen and answered any and all questions. He made it known that he and his team were there for us moving forward.

My surgery went well, the aftercare by his team and staff was exceptional. Now, I'm well on my way to recovery. I feel blessed to have found Dr. Gang and his team to help me on this journey. Without hesitation, I whole heartedly recommend Dr. Gang and his team to be your surgeon! "

-- Tim Franken, Mitral Valve, Valve Replacement, 08/27/2024

"I knew of his work as Dr. Gang performed a 5 bypass surgery on my good friend in 2023. Dr. Gang is a no nonsense surgeon and he lived up to his reputation... Excellent work as after my surgery I did not require any pain medicine. I was able to begin walking a mile just 10 days after surgery. "

-- Milton Yong, Aortic Valve, Valve Replacement, 08/20/2024

"I feel very fortunate that I was referred to Dr. Gang as my cardiac surgeon. He was very patient during our consult as my wife and I had numerous questions about the pending procedure. He made a promise to us both that he would give me 100 hundred percent of the best that he can be on the day of my surgery.

As promised, on the day of my surgery, he clearly arrived absolutely focused and had the surgical team in the same frame of mind. Further, prior to and post my surgery every physician assistant, nurse, and other members of the general staff could not say enough good things about Dr. Gang and his surgical capabilities.

Everybody that I have spoken with throughout this process, considers him to be one of the finest cardiac surgeons in the country. Dr. Gang and his staff and the greater Northwestern medical community have provided everything I could have hoped for from start to finish.

I don’t give out recommendations easily, but this is an easy one! If you need cardiac care, Doctor Gang should absolutely be on your shortlist."

-- Ler Brinley, Mitral Valve, Valve Repair, MitraClip, Coronary Artery Bypass, 08/12/2024

"Dr. Gang is without a doubt the best thing that could have to me during my cardiac episode. He expertly replaced a faulty aortic valve and gave me a new lease on life. He explained the entire procedure beforehand so there were no surprises entering into surgery. I am now 4 weeks after surgery and well on my way to getting my old life back. Thank you for saving my life!"

-- Richard Moulis , Aortic Valve, Valve Replacement, 08/02/2024

"Dr. Gang was excellent! Got me in quickly. Performed the surgery and talked to my family. Came to see me many times after the surgery. Very good to see him."

-- Terri Scaletta, Aortic Valve, Valve Replacement, 07/26/2024

"I am grateful I had Dr. Gang preform my aortic valve replacement. He was very straightforward and explained the options. Dr Gang and his team are dedicated to excellent care. Any questions I had before or after the surgery were answered. I am forever grateful for the superior care I received before, during and after my surgery."

-- Mary Langman, Aortic Valve, Valve Replacement, 07/24/2024

"Dr. Gang is an amazing surgeon who has a wonderful bedside manner. He spent an abundance of time explaining my condition, the procedure, and addressed all our questions and concerns.

He is professional, straightforward, confident, reassuring, and caring. I saw him every day in the hospital, even the weekend days. He has a fabulous team which I can’t speak more highly of. He replaced my aortic valve and now 4 weeks later, I have started cardiac rehab and am walking 3-4 miles a day 5 times a week. Dr. Gang and his team are a Godsend."

-- Kathi Miller, Aortic Valve, Valve Replacement, 07/23/2024

"I could not be happier with the way my surgery went. Everything was explained very thoroughly and they made sure we understood everything. I was always treated with respect and the whole team was very pleasant it made recovery a great experience. Would highly recommend Dr. Gang and his whole team for any one needing surgery."

-- Michael Little, Aortic Valve, Valve Replacement, 07/22/2024

"Doctor Gang saw that, with my weak health, it would be hard for him to do my heart surgery.

Thank God this doctor is very open minded. I was sent to a new doctor to see what was wrong with my weak and poor walking state. The new doctor found that I had PMR. In two days, I was walking and gained my strength back!

Doctor Gang took note and then saw the great shape I was in. Dr. Gang was then was so happy to get my surgery scheduled from being so open minded.

This man was always checking on me in the hospital even on Saturday and Sunday! I did well with his staff care and Doctor Gang got me home sooner! I thank God my path crossed with Doctor Gang!"

-- Ray Ward, Aortic Valve, Valve Replacement, 07/09/2024

I have energy & my whole outlook is more confident & happy. THANKS to Dr. Gang!!!"

-- David Jordan, Aortic Valve, Valve Replacement, 05/08/2024

-- Jeffrey Willour , Aortic Valve, Valve Replacement, 05/03/2024

-- Tom Pazienza, Aortic Valve, Valve Replacement, 03/06/2024

"Excellent results, complete recovery. I was recommended to Dr. Gang as one of the best surgeons in the area and I was not disappointed. If you need coronary bypass or an aortic valve replacement, I would highly recommend Dr. Gang."

-- Brad Pihl, Aortic Valve, Coronary Artery Bypass, 03/05/2024

"Doctor Gang repaired my mitral valve the end February 2024 and I am very pleased. He has a lot of energy and can be funny at times and his team was always attentive and got back to me if I had any questions or concerns. Everyone in his office was very friendly and helpful including the front desk people.

Doctor Gang and team were very conscientious about following up on the fluid by my lung with X-rays and visits and a procedure to drain the fluid once.

I would recommend Doctor Gyu Gang to anyone needing heart valve surgery. I had my surgery at Northwestern Central Dupage hospital in Winfield, Illinois and have always been happy with this hospital. The nurses I had on my stay were always nice, especially for Sophie from my first days after surgery."

-- Cheryl Stasch , Mitral Valve, Valve Repair, 02/27/2024

"I’m so thankful. First, Dr. Gang was able to do a mitral valve repair, even with my valve being very complex. He also fixed my Afib with a Maze procedure while fixing my mitral valve."

-- Cathy Schiller, Mitral Valve, Valve Repair, 02/12/2024

"Thank you Dr. Gang for your expertise in Heart Surgery, Valve Replacement and saving my life. Your concern and your staff's concern for your patients is remarkable. Excellent bedside manner. I have recommended you and your staff to many."

-- Lawrence Seyller, Aortic Valve, Valve Replacement, Coronary Artery Bypass, 02/07/2024

"Upon meeting my surgeon, I was quite nervous. However, from the moment his staff took me back and began taking my history and then Dr. Gang walking in the room all my fears went out the window.

They all sat and went over every detail, explained things in terms I could understand. They never rushed, took their time, and all had a great bedside manner.

By the time I walked out of my appointment/consult with Dr. Gang I was comfortable and all my apprehensions were gone. I would highly recommend Dr. Gang to anyone."

-- Barbara Hansel, Mitral Valve, Tricuspid Valve, Valve Repair, Maze Procedure, 02/02/2024

"In addition to an aortic valve replacement and coronary artery bypass graft, Dr. Gang also closed an existing hole in my heart. Dr. Gang was very highly recommended by my cardiologist and internal medicine doctor.

I found Dr. Gang to be very passionate about his work, very energetic with a great sense of humor. In addition to being a very skilled surgeon, Doc Gang’s “gang” are incredible and dedicated individuals. All questions were answered and all concerns were addressed by Dr. Gang and his staff.

While I do not wish to repeat this experience, the surgery was a great success. I would highly recommend Dr. Gang and his group of dedicated medical professionals to anyone facing cardiac surgery. You will be in great hands."

-- John Hagen, Aortic Valve, Valve Replacement, Coronary Artery Bypass, Maze Procedure, 01/30/2024

"Dr. Gang is a terrific surgeon. His office staff is excellent from the techs to the PA’s. Best of all, he repaired my heart valve. I highly recommend Dr. Gang and his excellent team."

-- Amy Hillstrom , Mitral Valve, Valve Repair, Median Sternotomy, Maze Procedure, 01/29/2024

"Dr. Gang is a great heart surgeon and person! Six months ago, I didn’t know I had a heart problem. When I was told about it, I didn’t know what to think or do. After talking with Dr. Gang in our first meeting I felt assured that it was going to be ok. I know nothing about heart surgery. But, I can tell you he is good at it. He explained to me what my problem was and how he was going to fix it in a way that I understood.

His physician assistants and office team are all outstanding as well. The surgical staff work together like clockwork. When in the ICU, Dr Gang or PA would check on me daily on how I was doing.

I am now going on 8 weeks and feeling great. I hope I never have to go through it again, but if I do... Dr. Gang is my guy."

-- David Cates, Aortic Valve, Valve Replacement, Root Replacement, 01/22/2024

"After a bit of internet searching, I found Dr Gang. I had many cardiologists tell me that mitral valve repair and aortic root replacement could not be done with the same operation.

Dr. Gang and his team were excellent in answering my questions and mentally preparing me for what lay ahead. As a reference point, all the testing prior to Dr. Gang indicated I had the issues previously described but no symptoms.

I wanted to know as much detail as possible about the surgery. Dr Gang sat with me in front of his computer and took me through the details. After surgery, he visited me multiple times in the hospital to check in with me. In summary, a very capable surgeon with a wonderful staff!"

-- Anthony Kobrinetz , Aortic Valve, Mitral Valve, Valve Repair, Valve Replacement, Root Replacement, 01/10/2024

"Dr. Gang was great. Very skilled. He explained things so that I and my family understood what was being done. He was very personable and attentive. Kept a close eye on me. I felt very safe with him. I would highly recommend him."

-- Brian Watt, Aortic Valve, Valve Replacement, 12/08/2023

"Dr. Gang, along with his staff, were exceptional, sincere and professional. He made sure that both my wife and myself were able to understand what the procedure entailed and what to expect following the surgery. He kept my wife informed of how I was progressing during the procedure, thus lessening her anxiety.

As a result of the heart valve replacement and aortic aneurysm repair, my latest CT scan shows that my heart is doing quite well with no additional areas of concern. I would like to thank Dr.Gang and his staff for doing such a fine job and giving me back a strong heart."

-- Jeff Lurquin, Aortic Valve, Valve Replacement, 11/27/2023

"Dr. Gang is a tremendously gifted heart surgeon. He is also a wonderfully kind human being who deeply cares for all of his patients.

Dr. Gang performed open heart surgery on me to replace my very impaired tri-cuspid valve. Dr. Gang even replaced my pacemaker with a more sophisticated model at the same time that he did my valve replacement.

I highly recommend Dr Gang for any type of heart surgery. He is the most dedicated and competent surgeon that I have ever encountered."

-- Paul Piro, Tricuspid Valve, Valve Replacement, 11/21/2023

"While my cardiologist recommended Dr. Gang, I knew I wanted Dr. Gang to perform my surgery when meeting with him the first time. I never felt rushed in any of my visits and he made sure to answer all my questions. His team is awesome and they all worked together to get me fixed up and back on my feet in a quick and healthy manner.

I would feel comfortable sending any of my loved ones to Dr. Gang if they ever needed heart valve surgery."

-- James Derrig, Aortic Valve, Valve Replacement, 11/13/2023

"Dr. Gang is a wonderful surgeon! His specialty is mitral valve repair and he has many years of experience (I believe he said 18 years) doing it. He also has a great personality. He really listens to your concerns and tries to address them. He is kind and caring and has a great sense of humor, too. Just a fabulous person. I feel so fortunate to have met him and I am thrilled that he was able to repair my mitral valve!"

-- Elizabeth Ahlemann, Mitral Valve, Valve Repair, 11/08/2023

"Very Happy with Dr. Gang. A very satisfying discussion about what procedures were being done and why. He patiently answered my page full of questions about the surgery.

Dr. Gang stopped by my room several times in the first few days post-surgery to check on me, talk about how it had gone, and to set my expectations about recovery. Follow-up appointments with Dr. Gang and his assistants have been gone well, my additional pages of questions have been answered during each appointment.

Surgical results were just what we wanted. The valve and aortic replacements are working fine."

-- Raymond Essick, Aortic Valve, Valve Replacement, Root Replacement, Maze Procedure, 11/07/2023

"Dr. Gang performed a triple bypass surgery which offered significant challenges. His expertise and skills were life-saving for me. I'm now recovering and looking forward to a normal lifestyle again soon. I highly recommend him. His skills and care for my recovery were exceptional."

-- Rex Lowman, Pulmonary Valve, 10/20/2023

"I was nervous going into surgery. Dr. Gang assured me everything was going to be OK. He was right. Great bedside manner. I had total confidence with Dr. Gang doing the surgery. I am doing great. Thank you Dr. Gang."

-- Robert Ruppert, Mitral Valve, Valve Replacement, 10/11/2023

"The surgery went very well. If asked how the open heart surgery experience went, for such an ordeal, the surgeon, the nurses, the entire staff and Central DuPage/ Northwestern Medicine I rate an A+."

-- Laurie Seames, Aortic Valve, Tricuspid Valve, Valve Repair, Valve Replacement, 09/29/2023

"Encouraging, informative, and good bedside manners. Surgery was successful."

-- Bruce King, Aortic Valve, 09/22/2023

"Dr. Gang in my opinion is the BEST. He tells it like it is. He takes his time with you and answers all your questions. When I got home from the hospital I never felt the need for any pain medicine. His office staff is also incredible.

He has a great bedside manner and sense of humor. I would highly recommend him to anyone that needs his expert skills."

-- Donna Bauer, Mitral Valve, Valve Replacement, MitraClip, Coronary Artery Bypass, 08/19/2023

"Dr. Gang is very personable and exudes confidence which helps put you at ease before surgery. Ended up having a quadruple bypass and Maze procedure which went extremely well. I highly recommend Dr. Gang."

-- William Kennedy, Aortic Valve, Valve Replacement, Maze Procedure, 08/11/2023

"Dr. Gang was an outstanding doctor in every way regarding my treatment as a patient with his kindness, reassurance, explanations of my situation, and competence is repairing my mitral valve. I would highly recommend Dr. Gang to anyone needing his expertise."

-- Margaret Oloffson, Mitral Valve, Valve Repair, 06/14/2023

"The surgery was a great success! I had minimal pain and was able to recover within weeks. All the details of the procedures were explained thoroughly. The surgeon and support staff pre- and post-surgery did a great job which is a reflection of a team effort. I highly recommend Dr. Gang."

-- Art Melesio, Aortic Valve, Valve Replacement, 06/13/2023

"Dr. Gang is an excellent surgeon. He explained the valve repair procedure beforehand and was there for me after surgery as I recuperated and went home. I think I received great care from Dr. Gang and his team."

-- Charlotte Workman, Mitral Valve, Valve Repair, 06/07/2023

"Well-organized with well-planned process strongly executed by his staff. All staff involved and Dr Gang communicated extremely well with me."

-- John Ziah, Aortic Valve, Valve Replacement, 05/23/2023

"Doctor Gang was terrific from the first time I met him. His professionalism and confidence immediately puts the patient at ease about the upcoming surgery. His staff are the best. Super professional and helpful. My successful surgery was a result of Doctor Gang. "

-- John Woodson, Aortic Valve, Valve Replacement, 05/10/2023

"Dr. was very helpful in every way. Answered all my questions and made me feel very comfortable. He was available the day of surgery along with several of his team.

He was very kind, gentle and encouraging. My healing process was explained clearly and what the restrictions I would have. All of his team, in the office and in the hospital, were just as kind and gently and encouraging as Dr. Gang.

My healing went great and the results were very good when I saw two nurses, of PA as well as, when she removed the tape over the incision. Everything was gentle and encouraging, and positive. I could not be more comfortable or encouraged that I am. Dr. Gang and his team were OUTSTANDING. Thank you."

-- Linda Kittredge, Mitral Valve, Valve Repair, 05/09/2023

"I received the best care from Dr. Gang and his team. Very short incision (6 inches), both valves repaired, and he also fixed the aortic valve that wasn’t expected initially. The result was a very quick recovery. I am back to work after 2 months and feeling great.

Dr. Gang is a diligent, very experienced surgeon. We are so fortunate to live close by. While in CICU, I learned that the center is expanding, adding 2 more rooms. Unfortunately more people need surgery like this.

He is supported by a great team. The staff in CICU treated me with love. Thank you so much, Amanda, Dorothy, Kate, Ali, and many of you I don’t even know/remember your name, for giving me another chance to live!

And, thank you Adam for creating and maintaining this platform, tremendous help when we were the most vulnerable."

-- Joseph Z., Aortic Valve, Mitral Valve, Tricuspid Valve, Valve Repair, 05/03/2023

"On my first meeting with Dr. Gang, he was very confident and reassuring which significantly reduced my fear and appreciation about the surgery.

Immediately before the surgery, Dr. Gang and all his team again reassured me and made me feel that they cared were concerned about me as an individual and that I was in the best of care.

After the surgery, at the first post operative appointment, Dr. Gang greeted me with a smile and explain the extent of the surgery and how well it had gone. Everything that Dr. Gang told me to expect before the surgery was exactly as i found it to be after the surgery.

I was amazed that I had undergone such a serious and major a procedure with so little pain and discomfort. It has now been 7 weeks since my surgery and I would without hesitation recommend Dr. Gang to everyone requiring heart surgery. "

-- Mark Ruggie, Aortic Valve, Valve Replacement, 04/19/2023

"My experience with Dr. Gang was excellent. Dr. Gang patiently educated my spouse and I about my heart defect - explaining in detail (using doppler, MRA images, and even hand drawn pictures) what needed to be fixed – all in non-technical terms that we could understand. He then walked us thru all the options and included me in the decision making as to what type of valve would be best and the urgency of getting my aortic valve replaced – but always being very clear that it was my decision to make.

Dr. Gang and his entire staff prepped me as to what to expect from the surgery to minimize any surprises in regards to my post-surgery pain and recovery. Dr. Gang took time out of his busy schedule to personally stop in several times and talk to me in the hospital - for me to see how genuinely happy he was with my post-surgery results really inspired me during my recovery in the hospital. Dr. Gang really gave me the impression that he takes great joy in making his patients healthy again. Dr. Gang's entire staff of nurses and APNs were exceptionally professional and caring and patiently responded to the many questions we asked (even when we asked for them to explain something a second or third time). The staff also spent a lot of time with us making sure all our questions were answered as well as making sure my post-surgery recovery was as expected.

Dr. Gang is truly a talented, skilled, and compassionate surgeon. The experience that Dr. Gang and his staff bring to the table allow them to confidently cover all bases - they know exactly what to expect thru the entire procedure – and execute accordingly. The results of my surgery exceeded expectations thanks to Dr. Gang and his team!"

-- Ed Bielanski, Aortic Valve, Valve Replacement, Root Replacement, 04/11/2023

"I had my aortic valve replaced. Doctor Gang put a new valve in and also made it so they could put a TAVR in if needed, down the line. He has a nice bedside manner but I was more impressed by his surgical work. He is a great surgeon in my book."

-- Thomas Jelinek, Aortic Valve, Valve Replacement, 04/03/2023

"Dr. Gang is an excellent surgeon. He took the time to patiently answer a multitude of questions that I had. He and his staff were awesome! Surgery went great, valves were repaired and not replaced. In addition to the 2 valves repaired, they had to replace a tendon under my mitral valve and close a hole in my heart.

Surgery was performed at Central DuPage Hospital, and I have to say that the care there was amazing. The CICU staff were nice, kind, and always attentive and helpful. I have only high praise for the entire team and my experience there."

-- Marcia Snyder, Mitral Valve, Tricuspid Valve, Valve Repair, Median Sternotomy, 03/31/2023

"Dr. Gang was informative and caring from the first time I met him. He talked through options before recommending what he felt was the optimal approach. He has a talented and dedicated team that works with him both in his office and the hospital. I am thrilled with the result and would highly recommend him and his team."

-- Cheryl Laughridge, Aortic Valve, Valve Replacement, 03/14/2023

"Dr. Gang and the NM team are outstanding! We researched his reviews and I am so glad we chose him as my surgeon. It is hard to imagine that you can have open heart surgery, go home in 6 days, and only take a couple Tylenol for the minor discomfort.

I can’t say enough good things about Dr. Gang and his team. It has been 7 weeks since the surgery and I have been working 1/2 days. I am 70 years old. If he is not the best, he has to be in the top 5. I highly recommend Dr. Gang and his team, and thank them for fixing my heart!"

-- James Alongi, Aortic Valve, Valve Replacement, 02/22/2023

"Because of thickening of the heart muscle, Dr Gang performed a myectomy allowing the valve to function properly. Dr Gang and his team are extremely professional but caring. They talk to their patients in a way that is understandable. All concerns were addressed by Dr Gang's team. I would recommend Dr Gang to anyone who needs heart surgery. Thank you, Dr Gang. You are the best!"

-- Carol Shields, Mitral Valve, Valve Repair, 02/01/2023

"I was 100% happy with the care I was given."

-- Scott Christopher , Aortic Valve, Valve Replacement, 01/09/2023

"Dr. Gang is a expert at heart surgery. He came recommended by my cardiologist (head of department), my primary, and one of the local medical school deans. You're in good hands with him."

-- Steve Malmgren, Mitral Valve, Valve Repair, 01/03/2023

"Dr. Gang was kind and very reassuring. He answered all my questions. He did a totally excellent job repairing my two valves!

I was so happy that he was able to save the valves without having to do a tissue replacement! I would recommend Dr. Gang to anyone! He also has incredible experience having done over 2,000 of these operations!"

-- Larry Nelson, Mitral Valve, Tricuspid Valve, Valve Repair, 12/06/2022

"Dr. Gang saved my life. He is extremely knowledgeable and professional. His bedside manner conveys caring. Results are amazing. Minimal pain from the day of surgery and I feel so much better. I would highly recommend Dr. Gang at Northwestern Winfield."

-- Gary Grossklaus, Aortic Valve, Valve Replacement, 11/02/2022

"Dr. Gang gave me a 'second chance on life' by performing a very high risk surgery due to my underlying lung problems. He is very professional and has excellent bed side manner. He makes you feel comfortable because of his confidence in what he does."

-- John Bukas, Aortic Valve, Valve Replacement, Maze Procedure, 10/25/2022

"Doctor Gang was very straight forward from the start. He said what I needed done and what he was going to do for me. he did everything he said he would do, to make me come thru with flying colors. It was a very good experience and putting my heart in his hands was the best decision I made. I would recommend him to anyone. "

-- Jon Ausbury, Aortic Valve, Valve Replacement, Median Sternotomy, 10/18/2022

"Dr. Gang is a wizard, his skills are unmatched but for my money the real advantage they have is their staff. From the Nurse Practitioner(s) to the rest of the staff they made a difficult experience a lot more palatable. Thank you for my new lease on life!"

-- LP Klem, Aortic Valve, Valve Replacement, 09/07/2022

"Dr. Gang did an outstanding with my open heart surgery. He has a good personality and mixes in a little humor to help put you at ease. I would highly recommend him to anyone."

-- Douglas Jameson, Aortic Valve, Valve Replacement, 08/22/2022

"Best of the best! Dr Gang explained what was needed in simple terms to me and my wife and all possible outcomes. The surgery went great and I recovered well. Dr Gang is a true professional and a master of his craft. Would highly recommend! "

-- Jim Conway, Mitral Valve, Valve Repair, Median Sternotomy, 08/17/2022

"Dr. Gang is beyond incredible! He’s very confident in his skills, but very compassionate toward his patients. He made me feel comfortable the minute we started talking. I never felt any pressure when choosing the type of valve to use. Dr. Gang helped me understand the pros and cons of each type. I had no surgical complications and was well cared for during recovery. I truly cannot say enough good things about Dr. Gang!"

-- Brandon Beard, Aortic Valve, Valve Replacement, Median Sternotomy, 08/15/2022

"Dr. Gang - My deepest gratitude to you for repairing my mitral valve and the follow-up care from your team during my stay in the CICU at Northwestern Medicine Central DuPage hospital in Wheaton. You allowed me to live my life to its fullest without worry of an unexpected heart issue if not having this heart procedure.

I would highly recommend Dr. Gyu Gang to anyone who needs the same or similar heart operation. Thank you."

-- Stanley Nakamura, Mitral Valve, Valve Repair, 08/10/2022

"Dr. Gang had a professional, compassionate and patient presence. He thoroughly answered all my questions and reassured me that his ability would result in a positive experience with the end result being a healthy heart. His surgical ability was extraordinary. He paid close attention to the scare left behind. His staff was equally outstanding, friendly, thorough and compassionate. I would highly recommend his surgical gift to any candidate who might need such a surgery… mitral valve repair."

-- Rochelle Doty, Mitral Valve, Valve Repair, 08/10/2022

"Dr. Gang is a kind and gentle man that is surgically talented and highly skilled. At my first appointment for consult, Dr. Gang demonstrated his wonderful bedside manner as he helped my husband and I understand, in layman's terms, my choices and the procedure.

He patiently answered all my questions and was adamant about ensuring that I understood. Dr. Gang's team was very helpful and caring during my hospital stay. I looked forward to their daily visits as they listened to me and talked "with" me not "at" me.

I highly recommend Dr. Gang and his Team without reservation. One would be hard pressed to find someone more talented than Dr. Gang. All involved in my care helped to make this a very positive experience. They are the BEST!"

-- Mary Ann Kania, Aortic Valve, Valve Replacement, 08/09/2022

"Dr. Gang was amazing. From my first office visit to my after care visit he was kind, caring and passionate. He provided a clear understanding of my problem and the steps needed to fix it. As it turns out, when he got in there, the problem was significantly worse than expected and yet he was still able to do the repair as opposed to replace. For that I will forever be grateful."

-- MaryBeth deBolt, Mitral Valve, Valve Repair, 08/03/2022

"During the first few minutes of my first meeting with Dr. Gang he put me at ease and I was confident that he was the best surgeon for me. Later an acquaintance who was a top nurse at the hospital also confirmed that I could not be in better hands with Dr. Gang.

Dr. Gang’s education and training has been at the best schools in the nation. During the meeting he explained everything clearly and confidently and he did so with a sense of humor which reduced my fears.

The surgery was a complete success and afterwards Dr. Gang dropped in on me frequently to check my progress. His physicians assistants and nursing staff were also constantly monitoring my progress and answering all of my question.

During my recovery I also received visits from cardiologists on the team at Northwestern Central Dupage hospital where I had my surgery.

Over my years, I've always had great experiences with Northwestern Hospital at the downtown campus and now at Central Dupage. "

-- Peter Censky, Aortic Valve, Valve Replacement, 07/26/2022

"If you are fortunate enough to have Dr. Gang as your surgeon, rest easy. He is very focused on you and your heart. Very knowledgeable and explains the situation so you can understand. Very approachable and reassuring. Thank you Dr. Gang! you are the best."

-- Patricia Laria, Aortic Valve, Valve Replacement, 06/29/2022

"Dr. Gang performed the surgery excellently. He made sure to follow up and was concerned about my progress in the hospital and after. The surgery is great, no complications. Recovery was fast and relatively painless and easy."

-- Scott Olmstead, Aortic Valve, Valve Replacement, Root Replacement, 06/21/2022

"Dr. Gang is very pleasant, easy to talk to, and a "straight shooter" -- He tells it like it is. Gifted surgeon (I slept through the entire operation -- LOL). Recovery was unpleasant, but definitely better than the alternative -- and ZERO complications. Looking forward to many more heartbeats. Big shout-out to the nursing staff at Central Dupage Hospital -- they were also fantastic."

-- Rod Holmes, Aortic Valve, Valve Replacement, 06/10/2022

"When I first met Dr. Gang, I was comfortable with him immediately. He listens to all your concerns. I have a best friend who works at Central DuPage Hospital / Northwestern Medical And she was very happy to hear that Dr. Gang was going to be doing my surgery.

He cares about his patients. He came to see me just about every day when I was in the hospital to see how I was doing.

Dr. Gang saved my life. He replaced my damaged valve with a cow valve. I have a second chance at life now at 60. I am forever grateful to him. I am almost in my six weeks of recovery. And I am healthy and doing well. My new valves should last me 20 yrs. I highly recommend Dr. Gang and if I ever need another heart surgery he will be the Doctor I would call. "

-- Diane Burgos , Mitral Valve, Valve Replacement, 06/08/2022

"I am writing to recommend Dr. Gang at Northwestern Medicine because of the excellent care I received before and after my mitral valve surgery. Dr. Gang is a wonderful surgeon, and the staff is always helpful and kind. They ensured I had a smooth prep, surgery, and follow-up. I am so glad I chose Dr. Gang and would highly recommend him to anyone!"

-- Sue A, Mitral Valve, Valve Repair, 06/06/2022

"Words have escaped me to describe how wonderful Dr. Gang is. He was highly recommended by my cardiologist, my PCP, and my brother. He is described as an artist with valves and he truly demonstrated his skill.

I had severe regurgitation at the mitral valve, caused by MAC. It was very challenging surgery, but using all his skills, Dr. Gang removed the large embedded calcium deposit that was holding the valve open like a "tent pole", saved/repaired the valve, and stopped the leakage. 10 weeks post-op I'm walking 3.5 miles 3 to 4 days a week, participating in cardiac rehab classes 2 days a week, and feeling great. Dr. Gang's manner and personality instills confidence and calm; he explains everything thoroughly and answered all my concerns.

I had no pain at the incision and the scar is healing beautifully; I'm now just anxious to move forward with recovery, one day at a time. Thank you, Dr. Gang!"

-- Glenn Hansen, Mitral Valve, Valve Repair, 05/23/2022

"I am 7 weeks post-op and doing very well. Dr. Gang was highly recommended to me from people in the medical community. I am so thankful that I chose him to be my surgeon of choice. He was down to earth - let me ask questions and took his role as my surgeon quite seriously.

Bedside manner was wonderful - visited me every day while I was in CICU. He was professional yet friendly and approachable and encouraging which is exactly what I needed. I will highly recommend him as a gifted cardiovascular surgeon to anyone who asks me how my open heart surgical experience was."

-- Kathryn Camey, Aortic Valve, Valve Replacement, Maze Procedure, 05/20/2022

"Dr. Gyu was, very concerned, very attentive and I felt completely at ease with his team. We had a successful outcome, follow up was as good as you could get. Thank you Dr. Gang!"

-- Chris watson, Mitral Valve, Valve Repair, 05/10/2022

"Dr. Gang is fantastic. Hw was able to repair my mitral valve when several cardiologists told me it would be too difficult to repair and would need a replacement. He took the time to explain everything and made me feel very reassured that I would be alright after surgery."

-- William Kailus, Mitral Valve, Valve Repair, Maze Procedure, 05/09/2022

"Bicuspid aortic valve replacement. My experience with Dr Gang, Rebecca and his entire staff was wonderful. Everyone made sure I understood my procedure and what to expect. They were professional, friendly and extremely knowledgeable. They answered all my questions and made sure I understood their response. Dr Gang reassured me and I appreciated his directness. I would recommend him to anyone considering heart surgery. The whole group is AWESOME."

-- Norma Smolin, Aortic Valve, Valve Replacement, 04/26/2022

"Dr. Gang was great. He was helpful, encouraging and very positive. He explained everything clearly, before and after surgery. I did my own doctor search after I was advised that the TAVR approach was not an option. My queries/searches ultimately confirmed that Dr. Gang was the right choice for me. I trusted him with my life and he gave it back to me. Wonderful man."

-- Douglas Beck, Aortic Valve, Valve Replacement, 04/22/2022

"Dr. Gang has listened to all my questions. He was very patient and took time to discuss all options and solutions. He is the best!"

-- Renata Rojek , Aortic Valve, Valve Replacement, 04/18/2022

"As a physician myself, I did my research before picking Dr. Gang. He did an incredible job in repairing my mitral valve, and explained the entire procedure in detail, as well as all of my options and possible scenarios beforehand. I've only had to take Tylenol since 2 days after the surgery for the pain and feel better than ever! He has a great bedside manner but most importantly is an excellent surgeon. I will definitely recommend him to my patients needing heart valve surgery. "

-- Warren Wollin, Mitral Valve, Valve Repair, 04/04/2022

"I had my mitral valve replaced on March 28th and it's been just over four weeks since my surgery. I don't think I could possibly be any more impressed with Dr Gang and his team, they are a phenomenal group. Took the time to answer questions and made sure I was comfortable and confident every step of the way. Thank you Dr. Gang!"

-- Tom Henaghan , Mitral Valve, Valve Replacement, 03/28/2022

"I am very fortunate to have had Dr. Gang do my aortic valve replacement.

I feel like he has saved and renewed my life. It has now been 6 weeks since my surgery and I am feeling great! During these 6 weeks I have not felt any pain and have not taken any pain medications. It is truly miraculous transformation of my life! Thanks you Dr. Gang!!"

-- Larry Peterson, Aortic Valve, Valve Replacement, 03/18/2022

"Dr. Gang and his team were excellent to work with. There was someone in to see me every day that I was in the hospital recovering from surgery. Dr. Gang and his team had a wonderful bedside manner. They were all able to answer my families and my questions quick and in a way we could understand prior to, during, and after surgery. It has been a month since my surgery and I am still recovering from my successful surgery. I would highly recommend Dr. Gang and his team. They are all knowledgeable, honest, and a privilege to work with. "

-- John Wagner, Pulmonary Valve, Maze Procedure, 03/07/2022

"Extremely happy with the results of my surgery done by Dr. Gang and his team. Excellent surgeon, very attentive, and highly recommended."

-- Matthew Mueller, Mitral Valve, Valve Repair, 03/01/2022

"Dr. Gang was excellent and just a great guy. He explained exactly what he was going to do to repair my mitral valve and answered all my questions concerning my surgery. I can’t say enough about him and his staff... They were excellent. Everything turned out great and I feel better than ever. If you're looking for a surgeon to repair your heart, he’s the one you want!"

-- Craig Wellick, Mitral Valve, Valve Repair, 03/01/2022

"Dr. Gang and his team did a terrific job on my mitral valve repair. His pre-op preparation was very inclusive on all details of the operation. We had a plan to repair/replace the valve with a full understanding of each option. From check-in to discharge, Dr. Gang and team were very patient and very helpful throughout the full process. I wouldn't want any other surgeon working on my heart."

-- Joe Sitzman, Mitral Valve, Valve Repair, 02/15/2022

"Dr Gang was phenomenal. He seems to convey a sense of peace and calm when he walks in the room. He spent a lot of time addressing my concerns and fears.

This was my second open heart surgery (first one was cardiac bypass) and I was having flash backs to my recovery from that. He checked on me every day in the hospital and made sure I had no follow up questions. My recovery from this surgery has been much easier than the last time.

His office staff is also amazing. They always responded to questions on MyChart quickly and followed up with a phone call if needed."

-- Deborah Kamperman, Aortic Valve, Valve Replacement, 01/31/2022

"Dr. Gang was very easy to understand and was direct about my issue. He stressed the importance of timing without alarming me. He was always willing to answer my questions. His bedside manner was positive and indicated a strong interest in my recovery. The results have been excellent and my recovery has been reasonable and fast. I am deeply grateful to Dr. Gang for his skill and positive manner. I would be happy to recommend Dr. Gang to anyone in need of his skills."

-- John Nicoll, Aortic Valve, Root Replacement, 12/07/2021

"I had a very good experience and follow-up with Dr. Gang."

-- Bradley Gratton, Aortic Valve, Valve Replacement, Transcatheter, 11/08/2021

-- David Kratz, Aortic Valve, Valve Replacement, Root Replacement, 10/26/2021

"Dr. Gang made me comfortable from our first meeting and throughout all my experiences with him. He and his staff are very patient-centered, willing to answer all questions, and very professional. Dr. Gang and the entire staff at Central Dupage Hospital made me comfortable throughout my initial and extended recovery.

At one-month post-surgery I am very happy with the results, and I'm very grateful to Dr. Gang and the hospital staff for helping me through it."

-- Rich Majerus, Mitral Valve, Valve Repair, Median Sternotomy, 10/13/2021

"Dr. Gang explained the surgery well, rounded on me afterwards, and continued managing my care when I had fluid on my lungs.

He was genuinely concerned for my well-being. I had no issues with the new valve and appreciated his expertise in performing this type of surgery."

-- Susan Lathrop, Mitral Valve, Valve Replacement, Maze Procedure, 10/11/2021

"Even at the age of 78, I couldn't be more thankful to have a great surgeon like Doctor Gang and his partner handle my heart surgery! He explained every thing so well that I went into the surgery full of confidence that all would be well handled. I came through the operation with very little pain or concerns. To me, Dr. Gang was my hero and I would recommend him very highly to anyone needing heart surgery!"

-- Lester Lingenfelter, Mitral Valve, Valve Repair, Root Replacement, 09/13/2021

"Dr. Gang is wonderful. He took time to explain my problem, in detail, and how it could be fixed. He has a lot of experience with this type of surgery, so I had full confidence in him and his team. I was not disappointed. I felt well taken care of. I highly recommend Dr. Gang. He’s a “rock star.” "

-- Eunice Ann Hassall, Mitral Valve, Valve Repair, 09/08/2021

"Dr. Gyu Gang and his staff were great. They kept my family informed during my surgery. He replaced my aortic valve and cleaned calcium out of my heart. Before the surgery, they clearly described the medical condition being treated and all the options that were available to me. I highly recommend Dr. Gyu Gang and his entire team."

-- Jack Schroeder, Aortic Valve, Valve Replacement, 09/03/2021

"I had Hypertrophic Obstructive Cardiomyopathy (HOCM) and Dr. Gang performed a septal myectomy to fix this problem and also added an Atricure clip while he was in there to prevent future possible problems. Dr. Gang and his PA had a great bedside manner and truly care about their patients. I am feeling much better now and probably added 20-30 years to my life. Thank you Dr. Gang!!!"

-- Bob Blaho, Mitral Valve, Valve Repair, Transcatheter, 08/20/2021

"I seldom write reviews but I'm happy that Dr. Gang is my heart surgeon. He explained things clearly all along, kept my family informed during my surgery, and completed the surgery successfully. I feel better already, just 5 weeks later.

I'm grateful for his and his whole team, including his PA Dororthy Anne Fedor, for saving my life. "

-- George Stenitzer, Aortic Valve, Valve Replacement, 07/09/2021

"About 0.6 CM of Staph bacteria was found on my aortic value. Doctor Gang laid out a plan to replace it within a week of finding the bacteria. The surgery was an overwhelming success. At 67, the breast bone healed rapidly, the scars are barely noticeable and most importantly -- my heart is running like a fine tuned engine. Thank you Dr. Gang for saving my life!!! "

-- Randolph Duerr, Aortic Valve, Valve Replacement, 07/09/2021

"Dr Gang is the best. He’s very concerned for his patients. Easy to talk to and takes all the time you need. I feel so much better after this surgery. I would recommend him for any medical condition he takes care of. I love you Dr Gang. And may God bless you."

-- Karen Lynch, Aortic Valve, Valve Replacement, 07/07/2021

"I could not have been more pleased with Dr. Gang. He exuded confidence which gave me great comfort in the coming very complex procedure. Dr. Gang has my highest recommendation and sincere thanks for such a fine job."

-- Mike Krueger, Aortic Valve, Mitral Valve, Valve Replacement, Root Replacement, 07/02/2021

"Dr. Gang was very open and concise in explaining all aspects of the surgery. I then became more comfortable in proceeding with the surgery. I didn't realize the proficiency of his entire staff including bedside manner until post surgery. " Impeccable ".

The surgery and my recovery went better than I ever expected, even when I first came totally out of sedation I felt good enough to go home. I would recommend Dr. Gang to anyone.

Thank You Dr. Gang!"

-- James Nechay, Mitral Valve, Valve Replacement, Maze Procedure, 06/22/2021

"Dr. Gang really helped me understand the severity of my mitral valve regurgitation, taking the time to share the TEE imagery. He shared his perspective on surgical repair solutions once the cardiac team determined that drug therapy was not a good long-term solution.

I personally researched robotic heart valve surgery as an alternative including a helpful second opinion from Mayo Clinic. I chose to stay local with a cardiac team I learned to trust and only received outstanding care from ER at Delnor to ICU/step down units at CDN. Dr. Gang communicated directly and clearly. He updated my family after surgery and they had positive comments about him and his communication with them.

I know I made the best decision to have Dr. Gang and his team (with cardiologist, Dr. Karmali, who made the initial diagnosis) for my short and long-term care. My recovery was quick with relatively little pain with some discomfort and fatigue which was predicted by cardiac team.) Ask questions! Do your research! Both allow you to gain confidence in your decision to move forward (or not.)"

-- David Blackburn, Mitral Valve, Valve Repair, Maze Procedure, 06/16/2021

"Dr. Gang saved my life at 75 years old. My mitral valve was leaking at 50% and I could hardly breath!

He and the Northwestern Medicine team made me a young man again. Even at 75, I am still very active for my age!

I had very little pain and only a six-inch scar. His bedside manner was awesome! Thank you Dr. Gang!"

-- Ronald Kammes, Mitral Valve, Valve Repair, 06/08/2021

"Dr. Gang was recommended to me by my Cardiologist. I was told he's the best there is and I certainly agree with that. He saw me several days after I saw Dr. Severino and he explained everything to me and my daughter. He took plenty of time with me and while I was scared I knew that he was the right choice for surgery.

My surgery went so well and it is now 5 weeks since the surgery and I am recovering very well. He and his PA's saw me everyday in the hospital. I am so pleased with the results of a very scary surgery for someone who has never had serious health issues. He is very friendly and caring and I knew he was the right person for this surgery. I have every confidence in him and would recommend without question to anyone who needs valve surgery."

-- Ann Hatt, Mitral Valve, Tricuspid Valve, Valve Repair, 05/12/2021

"Fantastic Doctor and staff. I felt confident that I was in good hands with each member of the staff. They were very caring and informative."

-- Donald Kobyleski, Mitral Valve, Valve Repair, Maze Procedure, 04/21/2021

"Surgery went smoothly, Dr. Gang and his team spoke to me frequently answering my questions and asking me questions, keeping me well informed. I'm happy with the results!"

-- Alan Potyen, Mitral Valve, Tricuspid Valve, Valve Repair, 04/13/2021

"What an excellent and positive experience prior to and post surgery. Dr. Gang educated me on the entire process as well as the specifics of the new valve I would receive. I was very comfortable and confident going into the surgery and was well taken care of post surgery. Highly recommend!"

-- Paolo Aristodemo, Aortic Valve, Valve Replacement, 03/30/2021

"I have nothing but praise and humble thank you for such a fabulous surgeon; who, in my opinion, saved my life with a dual surgery...mitral valve and double bypass. Dr. Gang showed his highly accredited skills for this more difficult surgery. His team of assistants were great...very caring and took the time for questions, etc. Really appreciated Ellen Daly, PA and all her time....very patient!! She was great!!! And a special thank you to Dorothy, CA, and Katie.

If one ever needs a top heart valve surgeon, I highly recommend Dr. Gang!! God Bless them all...from the bottom of my heart...deepest gratitude and a zillion thanks!!❤"

-- Connie(Carleen) Marx, Mitral Valve, Valve Repair, Valve Replacement, Median Sternotomy, 02/19/2021

"Dr. Gang is a pleasure to talk with. He explained everything about my operation in language that made it clear to me of the pro and cons of having or not having my operation. I had the operation and the results are excellent! Dr. Gang's mission in life is to care for and help people and when you meet him it is obvious."

-- Robert Soucek, Aortic Valve, Median Sternotomy, 02/03/2021

"Dr. Gang is direct and to the point. Very knowledgeable and always on time. His PA's and staff are great."

-- Michael Janco, Aortic Valve, Valve Replacement, Root Replacement, 01/22/2021

"I am a 57 year old woman who has lived a healthy and productive life. I was a social worker for 30 years working for the same company. After experiencing health problems, which I did not understand, I decided to retire early due to dizzy spells, breathing problems upon exertion, cognitive issues and complete exhaustion. I had occasional heart pain and I felt exhausted at all times. I was not functioning as I had in the past so I went to the doctor to see my GP, Dr. John Vaikutis. He checked my heart and told me that I had a murmur in my heart. He asked that I go get an echocardiogram which was very non-invasive. The results were not good and I am sure my heart problems kept me from functioning in the way I usually performed.

Once the test results were examined, Dr. Vaikutis called Dr. Gyu Gang, a cardiac surgeon. Dr. Gang got me in the office within a couple of days and talked about my condition. I met with Dr. Gang and he told me that I would need to have a new aortic valve placed in my heart and that this would entail open heart surgery. He also explained that I had a bicuspid aortic valve which was a birth defect and this blew out my aortic valve. Dr. Gang was straightforward, compassionate and spent ample time explaining my current situation. Open heart surgery was certainly not on my mind but I felt confident that Dr. Gang would take good care of me.

It would be unfair of me not to take the time to discuss Dr. Gang's team. He had 4 Physician assistants, many great nurses and other doctors watching over me while I was in the hospital. I had this uncanny feeling that all team members were in tune with each other which helped my recovery.

There are a couple of suggestions I would have for anyone going through heart surgery. Do not over pack your bag as I did. I do not think I got out of my gown for days. Keep up on pain control and talk with your doctor about their expectations about pain control. It hurt badly. Report to doctor appointments in leopard skin pajamas, LOL.

The last thing I will state is that my family member was going to fly me to Cleveland Clinic to get this surgery. After meeting Dr. Gang and his team and actually going through the experience of heart surgery I would always rather be at home than in some hospital where I do not know a soul. I am sure Cleveland Clinic is a good hospital but I got the best care at Central DuPage Hospital in my own town."

-- Melissa Kroll, Aortic Valve, Valve Replacement, 01/13/2021

"Dr. Gang is an excellent surgeon. He has also assembled an incredible staff to take care of all of his patients and do everything necessary to ensure their recovery. Dr. Gang saved my life and I would recommend him to anyone needing heart surgery. I am forever grateful."

-- Gregory Mongolis, Pulmonary Valve, Valve Replacement, 01/13/2021

"Dr. Gang and his team were a God Send to me and my family. I was born with a TSD and did not realize the damage that it had done to my Tricuspid valve. Dr. Gang was able to repair the valve and gave me a new lease on life. I had no idea that the problem with my valve had caused my heart to enlarge. I am so very Thankful.

I love Dr. Gang and his entire team of nurses and nurse practitioners . His bed-side manner is great, he understood my sense of humor being a Home Ec. teacher and had just taught my students how to sew and how learning these skills can lead to another career.

As for me, I am doing great!!!! I have very little pain in the chest area and and am able to do things around the house like preparing small meals which makes me happy. I also not only want to Thank Dr. Gang but also thank Dr. Mark Ottolin, Dr. Sujith Kalathiveetil for their joint effort in finding out what was causing my medical problems. Dr. Mark Ottolin told me that Dr. Gang is the best surgeon out there to repair my heart and I have to agree. Thank you for your warmth and kindness!"

-- Linda Wray, Tricuspid Valve, Valve Repair, 01/11/2021

"The surgical results are remarkable, and far beyond what I expected. I was confident in Dr. Gang's experience with this surgery. All Dr. Gang's staff are thorough and professional. I would strongly recommend him to any potential patient."

-- Michael Hels, Aortic Valve, Valve Replacement, Median Sternotomy, 12/23/2020

"Dr. Gang's bedside manner was excellent and the result of the surgery is great. I haven't felt this good in a long time."

-- David Shumway, Mitral Valve, Valve Repair, 12/02/2020

"He is a great surgeon. I felt confident to have my life in his hand. The result was great! I have not had any other heart issues after the procedure."

-- Vasu Sirinit, Aortic Valve, Valve Replacement, Root Replacement, 11/30/2020

"From the day I found out there was an issue with my heart, the Rollercoaster ride was rapid. I met so many doctors and care providers in 3 days, and ultimately I was told by Dr. Gang I was in heart failure and needed surgery immediately. He and his team were diligent in getting my care plan in place and following me as I prepared for surgery.

I could not ask for a better team to guide me through this frightening diagnosis. The level of professionalism and care was beyond expectations. Any calls to the office were returned immediately and all questions were answered in terms I understood. During the procedure my wife was updated multiple times and reassured that all was going well.

Dr. Gang and his team are above and beyond the best I could have found and my gratefulness for his care in saving my life is immeasurable. "

-- Donald McQuern, Mitral Valve, Valve Repair, 10/23/2020

"Today is Thanksgiving Day and I wanted to share my gratitude for my healing heart this year. It has been challenging for so many people, but heart patients have had to still move forward during a pandemic. I was really blessed to have found Dr. Gang and his team from this website.

Every question and concern that I had for my mitral valve repair surgery was discussed calmly and with time given to explain each step along the way. Dr Gang's initial consultation was informative, supportive, and encouraging for a positive outcome. His skills are developed with experience from his years of specializing in complex heart repairs. Dr Gang's team of P.A.s, nurses, and techs are all part of having the patient in mind first. I knew this from when I first asked questions on the phone, that I would be in good hands. And I have been.

Central DuPage Hospital was an excellent hospital in the western suburb, Winfield, as an alternative to having highly skilled medical care with not only Dr Gang's team, but also the Northwestern Medicine Health System within this hospital. Every person who cared for me had the patient in mind first.

I am full of gratitude for these health care workers and for my positive recovery today. Thankful for life, thankful for all of those helping hands, and for support from family and friends. "

-- Linda Lowe, Mitral Valve, Valve Repair, Median Sternotomy, 09/21/2020

"I had my surgery two months ago and am extremely pleased with the procedures done and Dr. Gang's care for me. He explained what was going to happen and is follow up was super. I would recommend him to anyone. Last follow up visit with him today and I applaud his care and the great results!"

-- Bobbie Gold, Mitral Valve, Valve Replacement, Maze Procedure, 07/07/2020

"Dr Gang is a very talented surgeon and a miracle worker. From the first visit for my mother, throughout the entire process, he and his team were the most heartfelt compassionate and best at what they do.

He is number one and the best in my book!"

-- Linda Orvino, Mitral Valve, Valve Repair, 02/07/2020

"It was a great experience! From the moment I met Dr Gang, I felt very confident things would go well. He made you feel like a family member and that you had nothing to worry about! He visited me everyday I was in the hospital, always smiling!!

My results have been amazing! People can’t believe I had open heart surgery just 6 months ago! Healing beautifully, and feeling great!! Thank you Dr. Gang and your whole staff! Also everybody at Central Dupage Hospital/Northwestern!!"

-- Paulette Kern, Mitral Valve, Valve Repair, 01/06/2020

"Great surgeon. He was able to repair my mitral valve instead of replacing it. This was no easy task considering how badly my valve was damaged. Doctor Gang and his team visited me every day and answered all my questions. They were very kind and caring. It has been three weeks since my surgery and I feel great.

Updated: I again want to thank Doctor Gang and his team for the outstanding job repairing my mitral valve on 11/20/19. It's now 14 months since my surgery and I feel better than ever. I just visited my cardiologist and he said my heart sounds great. No reason to see him again for another year. Doctor Gang, I feel so lucky to have had you as my surgeon. Again Thank You."

-- David Merrrick, Mitral Valve, Valve Repair, 11/20/2019

"Dr. Gang was great. He answered my questions and made me feel so confident that my surgery would be ok. Six weeks into recovery and I feel so much better. Thank you Dr. Gang!"

-- Marcia Rader, Aortic Valve, Valve Replacement, 11/12/2019

"Dr. Gang is a very caring individual. I was very pleased with both him and his staff. I really appreciated his Physician Assistant Dorothy. Overall surgery went well. It was helpful that a nurse called my cell phone each step of the way."

-- John Driscoll, Mitral Valve, Valve Replacement, 11/04/2019

"Dr. Gang was excellent!! A "5-Star" procedure!!!"

-- jack burke, Mitral Valve, Valve Replacement, 10/21/2019

"Dr. Gang was fantastic!

In the beginning he was direct and serious. This is what I needed. My condition was worse than what I was aware of. My 5-hour surgery took 12 1/2 hours. My care and recovery was fantastic. Everyone was great. I was out of bed walking by the next day.

My spirits got a little low, after a few days. My wife told Dr Gang what I said. Dr. Gang expressed how well I was doing. That he was very pleased with my recovery, and I was doing better than younger patients with less surgery. He made me feel proud of myself. From that point he’d come in my room with a big smile, talking about how well I looked, the color in my face. He made me look forward to seeing him. In addition, other doctors would come in to see me, and tell me how fortunate I was to have Dr Gang.

One doctor said Dr. Gang was one of the best surgeons in the country. I responded that I didn’t know that, but I knew he was very very good. The doctor asked how I knew that? I said, Dr Gang told me! The doctor smiled and said he loves it when he does that. For me, that was very reassuring. Plus he was funny the way he told me. I believe a patient wants a confident doctor. It certainly reassured me!

Dr. Gang mixes seriousness with compassion and humor. Mix that with truly talented surgical abilities. Combine that with a fantastic staff that follows his lead, and brings their own abilities and personalities to the table. Combine nursing and a great hospital with good people and very good food, you’re all set.

I had NO chest pain, except when sneezing and coughing. I had some pain in my leg, that was used to retrieve veins for my 3 bypass’s. This was minor, and went away relatively quick.

Thank you Doctor Gang for your abilities and personality that saved my life. You are a Great Surgical Doctor and fantastic person. I could not recommend Doctor Gang enough."

"Dr. Gang saved my life! I was not worried about the procedure at all. His skills are amazing and he checked on me - even during the weekend. His team works like a well oiled machine."

-- Jasen Beymer, Mitral Valve, Valve Repair, 09/17/2019

"I was very pleased with Dr. Gang, PA Casey and the entire surgical team. I was well-informed prior to and after surgery and my hospital care was excellent."

-- Norman Niedergang, Aortic Valve, Valve Replacement, 09/11/2019

"I had known for some time that I needed to have this surgery but, I was unsure of where and who was going to perform it. I made an appointment to see Dr. Gang and was surprised at how soon I could see him. I had done my homework, reading his qualifications and reviews and had made a list of questions for him.

When my wife and I first met him we were both impressed at how he listened to my account of my medical condition. He was so patient and didn't seem to be in a hurry to see his next patient. His experience with the type of surgery I needed was comforting. Finally my wife asked if he would be willing to do my surgery, and he said, "Certainly". He explained the risks, and proceeded to answer all my questions. I actually felt relieved that I had found the right surgeon.

After the successful surgery, he saw me every day and his bedside manner was so calming, I felt he really cared about me as a person and not just another patient. Dr. Gang and his team always included me in my treatment, keeping me informed. I am home and recuperating now, looking forward to the future. I forgot to mention I am 73 years old. I would highly recommend Dr. Gang as my surgeon and my wife and I are glad that we chose him and his service."

-- Richard Cosco, Tricuspid Valve, Valve Repair, 08/19/2019

"My entire experience from beginning to end was incredible. From the first meeting with Dr.Gang I knew he was the surgeon for me, he was confident, calm & informative. The surgery itself went perfectly, he was prepared, and even though my repair surgery was more complicated than most, he fixed my broken heart. After the surgery he was there explaining things and checking on me, and encouraging me to begin my recovery, which has gone better than anyone could have expected. I was up walking that day, and am almost ready to return to my normal life 2 weeks out. Gratefully, Dawn Aldaz"

-- Dawn Aldaz, Mitral Valve, Valve Repair, 08/14/2019

"After researching all the thoracic surgeons and hospitals in the area, my family and I felt confident with the team of Dr. Gang and Dr. Tomasko at Central Dupage Hospital in Winfield. The doctor ordered all the pre-tests and we felt that he was prepared to discuss the results with us in great detail, but that we could easliy understand, at my first consultation, and we never felt like we were rushed, as we had many questions during this appointment. It was easy to schedule the surgery date, the doctor was very flexible with my crazy schedule. The day of surgery, the entire team took great care of me, prior to, during and after surgery and my family with frequent updates during the procedure. Each day post-op I was visited by one of the many cardiologists or surgeons in the group to check on my status and answer any questions I may have had. I only needed 2 post-op appointments with the surgeon, to see how I was doing, check my incision site, and provided feedback to my questions and/or concerns. In the event of any cardiac event in the future, I would hope that this team would be on call, or available to take care of me, but I feel I have learned enough from them to make the appropriate changes in my life that I would prevent me from crossing this path anytime in the future."

-- CHeryl Taylor, Mitral Valve, Valve Repair, 07/02/2019

"Dr. Gang was extremely professional throughout the entire process from diagnosis to surgery to after surgery follows-up. He explained my valve issues and the required surgical procedures clearly. He also described my expected after surgery results and long term benefits of the procedure. Dr. Gang and his team at Central DuPage Hospital were exceptional in both the surgery and after surgery care in ICU. My recovery time period has exceeded my expectations and I am well on my way to return to the golf course and bike riding. I highly recommend Dr. Gang and Central DuPage Hospital."

-- robert settles, Aortic Valve, Mitral Valve, Tricuspid Valve, Valve Repair, Valve Replacement, 06/26/2019

"Dr. Gang is the best cardiac surgeon in Chicago-land. He and his team performed a life-saving procedure on me that replaced my calcified bicuspid aortic valve and at the same time repaired an aneurysm in my aorta. I owe my life to him and his excellent team. The results of the surgery were nothing short of perfection. I really did not experience much pain or discomfort after the surgery. I was off of pain medication within 2 days of the procedure. Dr. Gang's bedside manner is the best and I always felt safe in his hands throughout the procedure and post op, If I had this to do over again I would definitely pick Dr. Gang to do it and I would highly recommend him to anyone facing heart surgery. "

-- Raymond Feld, Aortic Valve, Valve Replacement, Root Replacement, 06/18/2019

"As a senior, I have experienced those that produce shoddy, incomplete or must do over work, and have found many that produce good work. Then there are the masters of their craft, Dr. Gang is a master. He performed four surgeries in ‘one’ on me. A Maze procedure, replaced the Aortic valve and repaired the Bicuspid & Tricuspid valves. In addition to his talent, he is a caring, compassionate man, and checked in every day after surgery. After a few weeks, I am back to everyday activities. Thank You Dr. Gang for extending my life!"

-- Jim F, Aortic Valve, Mitral Valve, Tricuspid Valve, Valve Repair, Valve Replacement, Maze Procedure, 06/17/2019

"Dr. Gang and his group are fantastic. He discussed and helped me choose the right valve for me. He is a great surgeon-my incision is smaller than expected and healing very well and I happily did not require blood transfusions. Recovery is going extremely well and I am thankful everyday that he was my surgeon."

-- Heidi Rockwood, Aortic Valve, Valve Replacement, Median Sternotomy, Bloodless Surgery, 06/05/2019

"Dr. Gang was PERFECT! Couldn’t be happier. Would highly recommend Dr. Gang."

-- Kenneth Niemeyer , Aortic Valve, Valve Replacement, Maze Procedure, 05/24/2019

"From my introductory visit, through pre-op and post-op, I never felt in better hands than with Dr. Gang and his team. The initial visit with Dr. Gang put my wife at ease and validated my research that he was the surgeon to conduct my Aortic Valve Replacement and to repair the aneurism on my aorta. The entire process with Dr. Gang and his team was a well conducted symphony with everything in harmony. Every step of the process was well coordinated, professional and executed with precision and accuracy. My operation took approximately 3.75 hours, I was out of intensive care within 24 hours, was walking within 48 hours and I was back home within 4 days to start my recovery. During this time Dr. Gang exhibited an outstanding bedside demeanor as did his staff and associates. I could have not have been more pleased with Dr. Gang and the outstanding results that he delivered. In short, Dr. Gang, his team and associates can best be describes as "Best-in-Class." I owe him and his team a better and extended life. Should I ever need any similar surgery in the future, he is my guy!"

-- Gary Gadzinski, Aortic Valve, Valve Replacement, 05/15/2019

"On May 14, 2019, I had my aortic valve replaced as well as having my heart muscle trimmed. On July 23rd, I hiked in the mountains of Colorado to 12,848 feet. It was great! I could not have done it before the surgery. Dr. Gang was great with a very positive outcome."

-- Stanley Grismore, Aortic Valve, Valve Replacement, 05/14/2019

"Dr Gang’s surgical skills & care provided me with an excellent post operative result."

-- Thonas Rimac, Aortic Valve, Valve Replacement, 03/12/2019

"Dr. Gang is an incredible surgeon. I interviewed a couple of different surgeons and Dr. Gang above all was the best. He explains everything that is going to happen before the procedure. During the surgery and after the surgery he makes you feel like he is part of your family and really cares about you.

My procedure went well and by week 4 I was driving, no pain meds and started rehab to get back to exercising.

Dr Gang his staff and Central DuPage/ Northwestern Hospital are the best. Thank to Dr. Gang , his staff and the Hospital. "

-- Carole Feigley, Aortic Valve, Valve Replacement, 02/25/2019

Thanks to everyone for all their efforts and care!!!!!"

-- Thomas Johns , Aortic Valve, Valve Replacement, 02/12/2019

"Dr. Gang's bedside manner was great. He and his staff listened well and answered all questions I had. The surgery was on a Tuesday and was home by Friday. I was able to go back to work part-time at 6 weeks post-surgery and will be full-time at 8 weeks post-surgery."

-- Laura Oscarson, Mitral Valve, Valve Repair, 01/15/2019

"Easy to talk with. A calming influence in the face of significant surgery. The entire team works very smoothly. The operation was very successful as well as mostly pretty comfortable. Granted they opened my chest but my knee operations were more “noticeable “ than my valve replacement has been. Thanks to all!"

-- David Altekruse, Aortic Valve, Valve Replacement, 01/04/2019

"I would truly recommend Dr. Gang to any and everyone that would need heart surgery. Dr. Gang gave my wife and I an explanation for what was going to be done during the surgery in terms we could easily understand. He took the time to answer all of our questions. Dr. Gang made gave me 110% of his knowledge and abilities. His bedside manner is phenomenal. Again, explained everything and answered every question. I am very happy with the results of my surgery. "

-- Dan Polka, Aortic Valve, Valve Replacement, Root Replacement, 12/17/2018

"Dr Gang "fixed the unfixable". My bicuspid aorta had deteriorated to the point where he said that he didn't know how I walked in. He is my hero!"

-- Charles Libby, Aortic Valve, Valve Replacement, 12/12/2018

"Dr. Gang made a welcoming and comforting presentation, on how he would do his procedure / tasks. Then, with good follow up visits, (including a drainage on lung), he & his team of service providers helped me feel good again so I can return to employer and live on!"

-- William Degorski, Aortic Valve, Valve Replacement, 11/19/2018

"Finding Dr. Gang was a blessing. I immediately realized he was an excellent surgeon. His intelligence, expertise and confidence made it an easy decision to proceed with valve replacement surgery. He explained everything that would happen. His positive attitude and vast experience gave me the peace of mind I needed. I trusted him with my life and he delivered by performing perfect surgery. He followed up afterwards with attention and care. He has the best job in the world... saving and extending lives! I am forever in his debt. I would recommend Dr. Gang to anyone needing valve replacement. You can look far and wide but you will not find a better surgeon than he is. I could never give him enough thanks and praise. He truly is the best!"

-- William Sebestik, Aortic Valve, Valve Replacement, 11/13/2018

"I knew the first time I met with Dr. Gang that he was the surgeon I wanted. I had a level 4 (very bad) leaking mitral valve. He is such a highly skilled and well trained surgeon. Northwestern is very lucky to have him. My surgery was open-heart. He was very good at explaining what he was going to do. My recovery went very well. My wife and I knew I was in the right hands. My surgery was on a Friday. He came to visit me on Saturday and Sunday. I was able to go home on Monday. I love Dr. Gang. So does my whole family."

-- Allan Stover, Mitral Valve, Valve Repair, 11/09/2018

"He is a great surgeon and his staff are wonderful. They will take all the time in the world to listen and answer your questions. The ICU staff is wonderful."

-- Kim Jacobs, Aortic Valve, Valve Replacement, 10/16/2018

"My stepdad was the patient, but with our very first visit with Dr. Gang I was confident we had the right doctor. He was nothing but informative and reassuring through the whole process, I was more impressed with the many times he checked on my Dad in ICU the day of and next day after surgery. He was nothing but attentive."

-- Tracy Feece, Aortic Valve, Valve Replacement, 09/25/2018

"Dr. Gang was always very professional, yet personable. The surgery was performed in the amount of time that had been estimated without any complications. The results have been great and I've been recovering faster than expected. Follow up with Dr. Gang after the surgery was very positive and helpful. He's been available when we need him to be and ensures we understand everything we need to know. I would definitely recommend Dr. Gang to anybody in need of a valve replacement and most likely any other heart surgery."

-- Dennis O'Malley, Aortic Valve, Valve Replacement, 09/14/2018

"I interviewed Dr. Gang previous to my surgery and found him to be not only extremely knowledgeable regarding what I needed done (Mitral valve and Aortic valve replacement as well as a double bypass of the Right Coronary artery - 100% blocked and Left Descending Coronary artery -90% blocked) but also found he is very experienced in successfully performing surgery to fix these complicated problems.

He was very reassuring as to what the positive result would be which gave me the needed confidence to move forward. He has a good sense of humor and friendly manner that immediately put my wife and I at ease and coupled with his extensive positive track record and technical expertise, I willingly put my life into his very capable hands. The operation was a success and while recovering has it's ups and downs I was able to contact or meet with him and his very capable staff at any time to ensure I was on the right path and healing properly.

I highly recommend Dr. Gang and his staff for this type of complicated life saving surgery and gladly state that I am living proof of his formidable capabilities in this area of medicine."

-- Roger Harmon, Aortic Valve, Mitral Valve, Valve Replacement, 09/05/2018

"Dr. Gang is an exceptionally skilled surgeon with a knack for putting patients and family at ease. He answers all questions thoroughly and completely and explains all expected outcomes or potential complications. Both pre and post surgery visits were very helpful. I highly recommend him for any heart surgery... In fact, I wouldn't recommend anyone else."

-- Steve Bosak, Mitral Valve, Valve Replacement, 08/29/2018

"Dr. Gang was awesome. He explained everything and took his time to answer my questions and my wife's. The surgery went great!"

"Professional, personable, confident, informative with a sense of humor, excited about his surgeries that makes a person feel at ease. A great "Gang Team". "

-- Lawrence Dalton, Aortic Valve, 07/31/2018

"From the moment I met Dr. Gyu Gang I felt at peace with his smile and ease of surgical explanation. He reassured me that all was good, nothing to worry about and that he would take excellent care of me. The surgery went well indeed and I was very blessed to have Dr. Gang as my surgeon.

His nurse Morgan was so amazing. She was there from the beginning of surgery, ICU, cardio ward, and my first office follow up visit. Everyone in the office was so professional and supportive during this emotional time.

Dr. Gang showed me confidence and trust needed to get through this surgery. I would highly recommend him to anyone considering heart surgery. He is the absolute best and has an outstanding support staff!"

-- Jeffrey Mallory, Aortic Valve, Valve Replacement, Root Replacement, 06/20/2018

"On June 6,2018, Dr Gang and his team performed a highly successful open heart surgery to repair the mitral valve and provide two by-passes for my heart. Dr. Gang is very professional and has excellent skills.

I feel great , and Dr Gang released me from his care on June 28th. Dr. Gang's operation and recovery procedures really exceeded my expections .He deserves the highest 5 STAR rating.

I highly recommend Dr Gang for open heart surgery."

-- David Opferman, Mitral Valve, Valve Repair, 06/06/2018

"Dr. Gang did an outstanding job. He was very professional and encouraging, did a remarkably fast surgery and during our first checkup was very encouraging. His confidence is high and he backs it up with a 100 percent great job. I would always recommend him in the future. His staff also did a wonderful job in every area."

-- Dave Krider, Aortic Valve, Valve Replacement, 05/25/2018

"Knowledgable and very professional Answers all questions directly and accurately; much abbreviated post op course; his team and all hospital personnel extremely competant. Excellent bedside manner"

-- Leonard Kelleher, Aortic Valve, Valve Replacement, Median Sternotomy, 05/21/2018

"Dr. Gang is very caring and thorough in describing the high risk surgery with me and my friends and family. He visited me at least once every day I was in the ICU and cardiac hospital floor. He performed this very specialized valve repair using my own tissue so I did not face rejection and let me know regularly how well I came through the procedure. I would recommend his expertise to anyone needing a heart surgeon."

-- Marcia Early, Tricuspid Valve, Valve Repair, Median Sternotomy, 05/01/2018

"There couldn't be a more caring, concerned surgeon than Dr. Gang. He explained my procedures thoroughly and answered every question I had. Thanks to his expertise, my recovery is without complications."

-- Jayne Hoalt, Aortic Valve, Valve Replacement, 04/06/2018

"Dr Gang clearly had read my file in detail before meeting me for the first time. He is an excellent listener and responded to all questions in detail - from all of my family. He explained things in terms that everyone understood and took as much time as was necessary to satisfy everyone, showing diagrams and imaging to help demonstrate the need for the surgery. He gave me great confidence that I was in good hands and he gave me the impression that I was his most important patient. I have no hesitation in recommending Dr Gang to anyone considering open heart surgery."

-- Edward Jacob, Aortic Valve, Valve Replacement, 03/23/2018

"Dr. Gang is the best if not one of the best in this field. Hearing that I'll will have an open heart triple bypass surgery was like "end of the world" scenario for me at first. But after Dr. Gang talked to me and my wife and explain/answer every questions we have about the procedure, we know we have the right Dr. His whole team is exceptional. From the office secretary to every member of his staff. His bedside manner is very professional but at the same time personal with the patient. He listen and attends to the patient's needs and concern. Now, 4 weeks after surgery, I'm brisk walking the treadmill for 30 minutes daily and pretty much getting ready to be back to my "normal" daily routines. Getting better each day. If you need surgery concerning your heart, you can never go wrong with Dr. Gyu I. Gang and his team at Northwestern Medicine. Highly recommended."

-- Joey Diaz, Mitral Valve, Valve Repair, 03/20/2018

"Excellent--kept me up to date on progress "

-- Jeff Haran, Aortic Valve, Valve Replacement, 03/13/2018

"Very compasionate and confident in assuring me a sucessful outcome. "

-- Charles Marlott, Mitral Valve, Valve Repair, 03/06/2018

"Excellent experience. Highly qualified, explained what would be done and how in a very understandable way. Answered any questions we had. Made eye contact when speaking to us. We ware very happy with the surgery and our current recovery, which is going very well!"

-- Julia/Ronald Hoppe, Aortic Valve, Valve Replacement, 02/19/2018

"Dr. Gang is the only doctor I would recommend for any issue with your heart. Dr. Gang was compassionate knowing how I feared any surgery. He took his time to explain the procedure and after I saw other doctors I knew that I would be in the best hands possible with Dr. Gang.

And, of course most of us know that Northwestern is "tops" in many fields of medicine including heart issues. Besides Dr. Gang's skilled hands he has a support staff that is always available for any questions or concerns.

Dr. Gang's nurse Morgan certainly helped me through a most stressful and scary time and like any "business" the "boss" has to have a great support staff, many doctors do not have a great support staff and believe me the support staff is VERY important especially during recovery.

The medical world is blessed to have Dr. Gang!"

-- Betty Loren Maltese, Aortic Valve, Mitral Valve, Valve Replacement, 02/06/2018

"Dr. Gang is an EXCELLENT surgeon. He explained the procedure to me in detail. I had every confidence in him. I had the Aortic Valve replaced and he repaired the Mitral Valve. I am extremely pleased with the result. You will be in good hands if Dr. Gang is your Heart Surgeon. "

-- Robert Cardinell, Aortic Valve, Mitral Valve, Valve Repair, Valve Replacement, 02/05/2018

"My surgery went amazing due to Dr. Gang and his wonderful caring team. He has a caring heart so I can't imagine why all his heart patients wouldn't heal quick! He cares more than I have ever seen a doctor care about his patients--and I do know I'm his favorite!!!"

-- Toni Young, Mitral Valve, Valve Repair, 01/09/2018

"I came to Dr. Gang after finding out that I needed another valve surgery. He and his staff were great right from the start. He recommended a mechanical valve which I completely agreed with, since the tissue valve I had done had failed 3 years ago. My surgery went really well and the nursing staff had me up and walking the next day! Dr. Gang, Whitney and Morgan stopped by every day during recover to see how I was doing. The nursing staff at the hospital were exceptional. I felt so much better after surgery than the first time I had it done which was pretty rough. I want to thank Dr. Gang, Whitney and Morgan for their top rate care and professionalism. I will definitely recommend them to anybody I meet who needs any heart surgery."

-- John Baker, Aortic Valve, Valve Replacement, 12/28/2017

"Dr. Gang is a fantastic doctor and surgeon. He is extremely down to earth and humble, with a bedside manner second to none. Additionally he is an extremely nice man. There were a few surprises with my surgery, especially with the aortic valve replacement, which was actually a re-replacement. He came to see me every day I was in the hospital, which was for 10 days. His concern for me and my wife were very genuine and much appreciated. Too often cardio vascular surgeons lose sight of whose important in the whole scheme of things. Dr. Gang did not. He was very detailed about the surprises that came up during my surgery, along with a very genuine concern for me, the patient. I can't imagine going through what I did with anyone but Dr. Gang. I would, without hesitation, recommend him to anyone who is looking at any kind of heart valve surgery. They won't find anyone better."

-- Bill Kalnes, Aortic Valve, Mitral Valve, Valve Replacement, 10/17/2017

"Dr. Gang turned what could have been a life threatening experience into an unbelievable life change. I can’t thank him enough."

-- Peter Kollias, Aortic Valve, Valve Replacement, 09/23/2017

"Dr. Gang is a wonderful and attentive surgeon. He is the reason I am able to write this recommendation today. When I first met Dr. Gang, I was frightened by the prospect of open heart surgery. Dr. Gang clearly explained to me what was wrong(in fact it was the clearest explanation I had ever received) as well as the treatment plan. He was by my sided when I came in for surgery and continually checked on me after the operation. Dr. Gang is a compassionate surgeon and is the reason I have a new lease on life!"

-- David Magee, Aortic Valve, Valve Replacement, Root Replacement, 09/20/2017

"I would first like to say that Dr. Gang saved my life. So for that I will always be grateful! He was extremely knowledgeable, thorough in explaining my surgery and took his time explaining any questions I had. I recommend him for a heart surgeon, you will be in great hands."

-- Christina Kowalczyk, Aortic Valve, Valve Replacement, 09/19/2017

"Dr. Gang and his team are awesome! I can honestly say that I was nervous at first not knowing what to expect, Dr. Gang made me very comfortable, was very informative, and answered and all my questions. I wouldn’t hesitate for a moment to recommend Dr. Gang! He is truly a great surgeon supported by a great group of highly skilled and professional nurses."

-- Margaret Lunquist, Mitral Valve, Valve Repair, 09/18/2017

"Dr. Gyu Gang did a fantastic job. I have several medical issues and he spent a considerable amount of time discussing my concerns and how we were going to get through a challenging surgery. Dr. Gang was with me every step of the way and I'm doing great. "

-- Deborah Walton, Mitral Valve, Valve Repair, 12/20/2011

"Like most surgeons, Dr. Gang was brisk but took all of the time necessary to answer my questions both pre and post op. The surgery was flawless and I was out of the hospital in three days and am back to running my 7 miles daily."

-- Patrick Miller, Aortic Valve, Valve Replacement, 11/10/2010

"Dr. Gang has performed hundreds of valve replacements and the only reason he has not yet done thousands is that he's young. He is a good listener and very well versed in the range of surgical and valve options. He did not hesitate to recommend a tissue valve for me. He stressed the need for a patient to shop around and feel comfortable with their surgeon - as a "sacred trust" is required. He also stressed that if I were to have any complications or issues that he "doesn't run" and he's fully responsible, accountable and owns up to his work. His office staff was swift and efficient with my short term medical leave paperwork. He is very confident and reassuring. Lastly, he also suspects I will outlive my valve and said he uses certain techniques to make it easier for the next valve replacement. "

-- Mark Berry, Aortic Valve, Valve Replacement, 09/02/2009

"I can actually state that I am extremely pleased with my surgeon from the first time I met him through his follow-up to date."

-- Anita Wise, Aortic Valve, Mitral Valve, Tricuspid Valve, Valve Replacement, 06/08/2009

"He is great, talented and as far as I am concerned no one can compare. I didn't have time to search for a surgeon was assigned to me. As one of the techs said, "Dr. Gang is a go to guy for valves." I totally agree."

-- Anita Wise, Aortic Valve, Mitral Valve, Tricuspid Valve, Valve Replacement, 06/08/2008
