Dr. El-Hamamsy

"I was born with a bicuspid aortic valve, with only two leaves instead of three. After 70+ years, the valve began to leak. As a result, the regurgitation was clearly audible during my annual physical in 2018, and my primary care physician referred me to Dr Alon Gitig MD, director of cardiology for Mount Sinai Doctors Westchester, who monitored my aortic stenosis and aneurism for 4 years before referring me to Dr Ismail El-Hamamsy, MD, PhD, Director of Aortic Surgery at Mount Sinai whom he considers: “not simply a brilliant aortic valve specialist, but also one of the best known aortic valve surgeons in North America.”

From the initial meeting in September 2022, Dr. El-Hamamsy and his surgical team at Mount Sinai hospital in NYC reflected a profound sense of trust, respect, warmth, and compassion. Dr. El-Hamamsy assured me that he "would take great care of me." For the next 12 months, he monitored my aortic stenosis and aneurysm, and dedicated time to explore various aspects of the surgical procedure to ensure I felt at ease. He helped me surmount my insecurities and my hesitations, providing me with the knowledge to make the decision on my own.

The surgical team also provided a comprehensive overview of what to expect post-surgery, during the recovery period. So, I decided to schedule my surgery with the gracious Leemor, the surgical team’s executive assistant, for Tuesday 12/19/2023, when it would be the least impactful on my job, and would allow me to be home recovering during the Christmas holidays.

The warm-spirited anesthesiologist, Dr. Ingrid Hollinger MD, who guided me through pretesting and surgery, and Dr Joseph Sweeney MD who performed my coronary catheterization, also demonstrated genuine care, following through in a most compassionate manner.

The entire team’s involvement in the surgical procedure, as well as post-surgery recovery in the ICU and subsequent transfer of post-surgical care to Dr Marc Miller, cardiac electrophysiologist and his team, fellow Dr Nana Gegechkori MD PhD and Helen Alexandroff NP, were simply marvelous in observing and treating the arrhythmia in my heartbeat.

The continuous communication during my aftercare at home was unprecedented, particularly Roberto Galao Malo NP, who guided me through every step of the way before and after surgery, demonstrating such humanity that I had tears in my eyes when I went to thank him.

The arrhythmia persisted at home and so, during the short week between Christmas and New Year’s, Galao immediately arranged for me to come in and be seen by the surgical team, Dr Elbert Williams MD, Dr Charles Laurin and Dr Lillyanne Chen MD, and cardiologist Dr. Tara Naib MD. This emphasized the team’s dedication to my well-being as a patient. I never felt alone. I felt like part of the family with an honored position on the team.

One month after the surgery, the cardiologist, Dr. Naib, scheduled me to start monitored exercises at the Mount Sinai Cardiac Rehab Center, participating twice a week for a duration of 12 weeks. My staying physically active during post-surgical monitoring further highlights the positive impact of the surgery and my swift recovery.

Overall, I’d like to express my sincere thanks for the exceptional care received at Mount Sinai, emphasizing the individualized approach, effective communication, and successful surgical outcome. I never expected to have had such an outstanding experience from beginning to end."
