I just had a tavi procedure at st Mike's toronto, by dr Alnasser, and WOW, totally impressed, kind and thoughtful, would totally recommend him.

Dr. Alnasser performed my PFO closure in a fairly urgent situation after I had two very unexpected strokes (while young and healthy). He rearranged schedules so I could have the surgery within 48 hours - all while kindly and compassionately explaining the procedure (with a sense of humour too). Dr. Alnasser has forever changed the course of my life.

Doctor Sami is extremely professional ,curteous and dedicted to his profession . Today, because of him and his team at St Michael Hospital Cardiac Investigation Unit , I literally got a new begining in life. I am deeply grateful and I highly recommend Dr Sami.

Dr. Sami Alnasser is simply the best! He did the PVO closure procedure of my nephew's hole in the heart. He is very caring, patient and takes time to explain and gives very great advices. We are so lucky to have been referred to him at St. Michael's Hospital at downtown Toronto. His administrative staff Amerita is likewise very kind, patient and very polite. Hope all other doctors and staff are like Dr. Sami and Amerita!

If I could leave Dr. Alnasser 10 stars I would. I recently met with him to go over some test results and he took the time to answer every question that I had in a clear and concise manner. He was incredibly knowledgeable (which I expected) but he delivered the results so thoughtfully and made me feel so assured. There was no arrogance either which was refreshing. Even his staff rave about him which I experienced while scheduling my appointment. Thank you Dr. Alnasser for making a difference and being different!

In June 2023, I had an angiogram performed by Dr. Alnasser and Dr. Moey, which led to a successful CABG procedure done by Dr. Yanagawa and his team at St. Mike's a few weeks later. Dr. Alnasser and his team's expertise and clear communication made the process smooth and stress-free. The support staff was attentive and efficient, contributing to a positive experience overall. I highly recommend Dr. Alnasser and the St. Mike's cardiology team for their exceptional care and professionalism

Dr. Alnasser was the cardiologist on call while I began my recovery from a SCAD heart attack last weekend. He answered all of my questions and treated them each with the same gravity. He took the time to ensure I was comfortable leaving the hospital. Thank-you Dr. Alnasser.
