"Recently, I had to correct a congenital heart issue that I've been facing since birth, but was only diagnosed in 2007.

A bi-cuspid aortic valve reduces the efficient flow of blood through the heart, in some cases dialating the left ventricle. Back in December, I had an MRI that confirmed my case required surgical intervention.

Here I am, two weeks post-op, thankful for Ismail El-Hamamsy and the team at The Mount Sinai Hospital and Icahn School of Medicine at Mount Sinai for a very successful Open Heart surgery.

Dr El-Hamamsy and team is absolutely the place for any aortic valve operation. Dr El-Hamamsy deliberately walked me through all my options and backed each one with data and evidence. He is also the best person to talk with; empathetic, nice, and caring, Dr El-Hamamsy is the complete package. Ultimately we set up a prioritized order for operation type (correction, Ross, bioprosthetic) and I went in with the confidence that he will do his best to accomplish the least invasive that would give me long term outcomes. Not many surgeons can offer all these choices.

During my procedure and stay, Dr. El-Hamamsy was assisted by his team, who included Dr. Chen, Dr. Williams, Dr. Vincent, and Dr. Sun. All of which cared about my recovery and brightened up my day. They are some of the most capable surgeons that I really wouldn’t mind going on a ski trip with; nice, kind, and intelligent.

The last person on the team Is the program coordinator, Leemor. Without Leemor the keys to the aortic valve kingdom would not exist. She is kind, patient, and really worked to ensure I could see the team (huge insurance fiasco). Her care for patients is above and beyond anyone you’d see in the world, especially for Heart Surgery.

Overall, a very positive experience, looking forward to seeing imaging that returns me to unrestricted function."

"I was diagnosed with aortic stenosis and bicuspid aortic valve 12 years ago. My primary and cardiologist monitored this yearly and watched as the stenosis became severe. I was referred to a local Long Island surgeon for a consult. I was told I needed open heart surgery as I was too young for TAVR.

I asked for a second opinion and this local surgeon sent me to Dr. El-Hamamsy. I was actually already scheduled for surgery on Long Island and got in to see Dr. El-Hamamsy 8 days before that scheduled procedure. I met with Roberto, who was wonderful, and Dr. Chen, who informed me that I'm a candidate for the Ross procedure. Then Dr. El-Hamamsy came and cinched the deal. He was wonderful. He agreed with my original surgeon that this must be done urgently. I took the next available appointment, which was 6 weeks away.

Everyone at Mount Sinai was amazing. From the pre-op staff to the OR staff, my amazing anesthesiologist, to ICU and step down on 7 West. And Leemor, in his office, must be given a medal of honor. She held my hand as we navigated insurance and pre-op issues.

On the morning of surgery he visited me in the pre-op area and I asked what plan B would be if he couldn't do a Ross Procedure. We agreed on a tissue/bovine valve. Within minutes I was getting an IV and getting on the table. Next I know I'm waking up in ICU several hours later. Other than still be intubated, I was fine. I was told that he couldn't do the Ross procedure because my pulmonary valve was quadicuspid so an Edwards valve was placed.

I spent one night in the ICU and was up walking the unit the next morning. I was moved to step down that afternoon and went home after 4 nights. Dr. El-Hamamsy visited me several times, and his team visited me twice a day. Dr. Chauvet and Dr. Chen seemed to come daily to see me and took the time to answer so many questions about my surgery and recovery.

Again, everyone I met with at Mt. Sinai was wonderful! The care of I received was amazing. I'm truly grateful for Dr. El-Hamamsy and his unbelievable team. Everyone is truly a gift from God."
