Dr. El-Hamamsy

"Dr. El-Hamamsy's highly sought-after practice is nationally and internationally recognized because his surgical prowess, superior patient-centered care, and exceptional multi-disciplinary team of highly skilled fellow-surgeons, physicians, nurses, and administrative staff who support patients in his care are second to none. I walked in for my Ross on Thursday morning and went home just three days later with minimal pain or soreness. Four weeks later, I'm walking briskly 3 or 4 miles a day (even on hills), have fully resumed my two full time job responsibilities, have had my medications reduced by 70%, and one of the team’s specialized nurses (Roberto Galao-Malo) still checks in on me twice a day for my vitals and to learn how I'm coming along. This is a top-notch team, one of the best surgeons in the world practicing in a setting and surrounded by people who treat patients not like another statistic but rather as family, yes family! Here’s an A-to-Z of my experience and why I highly recommend this practice.

The consult: I was struck by Dr. El-Hamamsy's ease and comfort during my initial consultation. There was no reason for me to worry because he and his team (enter Dr. Lilyanne Chen and Dr. Charles Laurin) thoroughly and confidently walked me through the surgery, answered all of my questions, transparently outlined all risks and possibilities, and laid out what to expect while in the hospital. Dr. El-Hamamsy's manner is gentle yet direct, sincere, comforting, confident yet empathic. I never felt rushed or that my concerns or fears were being discounted. After having achieved the kind of volume in aortic interventions or procedures very few surgeons in the country share - which is why he is also the Director of Aortic Surgery for Mount Sinai Health, the President of the Heart Valve Society - a prestigious international group - a mentor to other cardiac surgeons building their practices, and a published professor - he is very seasoned. Mount Sinai leads the world in Ross procedures, Dr. El-Hamamsy himself having performed the vast majority of those. After my consult, I knew I didn't need another opinion, I had just spoken to the best, so I booked my surgery with him right away. I had full faith and credit in his ability to Ross me with perfection and to navigate any complications that may arise with his experienced exercise of sound and precise judgment while backed by the enormous resources Mount Sinai has to offer.

The surgery: As he promised, my procedure was flawless, he called it 'textbook'. The incision Dr. Chen made is a short relatively inconspicuous straight line running along my sternum that just a month later is already fading. I was out of bed walking around the floor the very next day after surgery. My greatest discomfort wasn't chest pain nor soreness, but rather maneuvering all the connected wires and tubes in and out of the hospital bed.

Bedside manner, patient-centered care: Dr. El-Hamamsy visited me the morning of the surgery right before they carted me into the operating room. He came by to reassure me one last time, and with his trademark radiant smile and firm handshake I was ready to be taken in. He was one of the first persons I remember seeing after walking up in ICU. He communicated with my husband and family before they were able to see me. He visited me twice more while I was recovering in the step-down unit. The one day he wasn't there and on the day of my discharge, his fellow surgeons and physicians - Dr. Chen and Dr. Laurin made the rounds. They were never transactional nor insincere. I feel like they've all become family to me in some weird way. Certainly, their exceptional care and attention aided my speedy recovery and for that we shall forever be connected. I got to see them all again including Dr. El-Hamamsy during my post-op three week check in when again I was assured of being on the road toward full recovery and long-term quality of life.

The team backing Dr. El-Hamamsy: As I mentioned, Dr. Chen and Dr. Laurin are an extension of Dr. El-Hamamsy’s approach, ethic, and successful intervention. They were integral to my successful surgery and to my recovery.

The specialized nurses and nurse practitioners in the cardiac unit (ICU and step-down) at Mount Sinai are remarkable. All of them are highly skilled with exceptional bedside manner and patient care. Abel Andrada was instrumental in getting me up and about, educating me about my medications, and firmly encouraging me to moderate my exertion for the sake of my long-term recovery. He did this with professionalism and wit because a little levity during a stressful time when your mental health could easily suffer is necessary. He was patient with and welcoming of my boisterous big Greek family who took over the step-down floor! He was at all times concerned with my well-being and very protective of me.

Specialized nurse Roberto Galao-Malo who still checks in twice a day a month later, makes sure that Dr. El-Hamamsy's patients recover well long after their discharge. He will stay in touch twice a day to get vitals and to adjust post-op medications, as necessary. He is always a phone call or text away and accessible, even on the weekends. His mission is our flawless recovery, and he goes beyond the call the duty to keep us safe and well. He is truly exceptional and very knowledgeable.

But perhaps the unsung hero in Dr. El-Hamamsy's team is the glue that keeps it all together, the ambassador of the practice, the coordinator, the most patient facing person throughout the journey, our dispatcher, adviser, confidant, the unwavering, enthusiastic, knowledgeable, and most reliable, Leemor Selitto. Leemor is truly incomparable in healthcare! From scheduling the procedure and all related appointments or testing, to navigating insurance coverage questions and other inquiries, to being that friendly and trusted ear on the phone or online, she (literally and figuratively) held my hand throughout and continues to be a reliable and comforting resource during my recovery. Just like everyone else in this practice, Leemor has become family.

There truly is no other option when considering a heart valve surgery practice. Dr. El-Hamamsy’s got the most experience, knowledge, and biggest heart."

"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.

A second surgeon, Dr Lilyanne Chen, played a crucial role in my Ross journey. She spent a great deal of time with me going over the details of the surgery, came to the preop room to calm any last minute nerves before surgery, was present during my surgery and visited me several times afterwards while I was still in hospital. She also helped me out with an additional health concern not related to my heart. She was amazing and I cannot thank her enough!

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!"
