" You will never find a better surgeon for a Ross Procedure than Dr. El-Hamamsy. I am still shocked by how easily I got through my own Ross surgery. I entered the hospital Wednesday and walked out the following Sunday morning. I never had pain in my chest (only soreness), I never had arrhythmia nor lung issues, I was able to walk and climb stairs days after surgery, I was able to walk a mile within days of discharge (and multiple miles shortly after) and I now feel better than when I went in. I have experienced worse dental surgeries, I even ask myself whether I actually got a full Ross it was just too smooth. Beyond unbelievable surgical skill Dr. El-Hamamsy also has a remarkable publication record and is a recognized authority on the Ross Procedure. In fact, he helps surgeons at other institutions set-up their own Ross programs. Finally, Dr. El-Hamamsy is a pleasure to talk to- he is very polished, listens carefully, remembers details from previous conversations, never appears rushed, takes time to chat with family members and projects a reassuring confidence. While surgeons are important, support staff is critical too. Everyone from Dr. El-Hamamsy’s office was excellent with two standouts for me being Leemor Selitto, the very efficient and exceptionally kind coordinator, and Roberto Galao-Malo, the highly skilled and super good-humored nurse practitioner. I was also impressed with Mt. Sinai Hospital, the nursing staff was incredible as was just about everyone else there. Throughout this entire process I felt listened to, looked after and safe. I have nothing but enormous gratitude, admiration and respect for Dr. El-Hamamsy and the team of health care professionals who took care of me. I will never forget them. Thank you, everyone!"

"It probably goes without saying, but I was not looking forward to heart surgery. I was born with congenital aortic stenosis and had my first open heart surgery, an aortic valve repair, when I was 3 days old. I always knew I was facing another surgery in my future, but that didn’t make it any easier when the time finally came in my early 30’s.

What did make it easier was being introduced to Dr. Ismail El-Hamamsy. One of the first things you discover when researching aortic valve/root/Ross surgeons is that all roads lead to Dr. El-Hamamsy, who coincidentally is the newly named President of the Heart Valve Society. Even before meeting him in person, I was helped immensely by watching his online videos in which he methodically explains the different options for valve repair and replacement and more importantly, the vast data he has collected for long-term survival and quality of life associated with each option.

For me this new-found knowledge helped begin to ease the anxiety with a new sense of empowerment. Then I met Dr. El-Hamamsy in person. My mom came with me, and it felt a little like meeting a celebrity because we had watched so many videos, but he could not have been more down- to-earth and friendly, even humble in a cool kind of way. He took his time and answered all our questions and concerns. We came hoping to find out that I would be a candidate for the Ross procedure, and it turned out after carefully reviewing my tests sent from my cardiologist, he agreed that that was my best option.

As someone with extreme white coat syndrome, I consider bedside manner to be an essential quality in a doctor, and Dr El-Hamamsy is the gold standard. I lost all my sense of dread. He shook my hand and said “I’m going to take good care of you” and I knew he would.

And he did. The surgery was, in his words, a 100% success. He, along with the surgical team, came to my bedside every day I was in the hospital. To top that, 2 weeks later when I returned for my post op appointment (scheduled for 7am because he had to scrub in for surgery), we were told he had been up all night in emergency surgery and would not be available to see us. We understood and were happy to meet with his fantastically knowledgable NP, but at the end of the visit in walks Dr. El-Hamamsy in his scrubs, looking exhausted but there to say hello and answer any questions. When he says he puts his patients first, you can believe him.

And lastly, a word about the team Dr. El-Hamamsy has put together. As you research aortic valve surgery you learn that it is imperative to go to a center of excellence with a full team dedicated to the subject, and Dr. El-Hamamsy humbly always credits his team first and foremost. It is clear that each of them, like their captain, is at the top of their game, from the Program Manager Leemor who gets you started, to the OR team, the ICU nurses, and finally the NP Roberto who crucially follows your blood pressure after you return home.

For such a world-renowned in-demand surgeon, the whole experience surprisingly has felt more like being cared for by a small group of good friends who have the utmost concern for my care and comfort. I could not be more grateful. And PS... The scar is cool. I wear it as a badge of honor."
