7 Patient Reviews for
Dr. Unai

"Dr. Unai is a gifted heart surgeon at the Cleveland Clinic. I was blessed to have him perform my second aortic heart valve replacement procedure. I had the Ross Procedure where my pulmonary valve was turned into my aortic valve and then replaced with a cadaver valve. Now all my valves are human tissue valves and I feel great. Dr. Unai has performed this procedure many times.

I know I was a challenging case but he was able to get me through it and I am feeling great (9 months post op now). He is a very special man. I spent a great deal of time at Cleveland Clinic and heard many stories of how great his hands are and how many people he has helped. He has a great temperament and always took as much time as I needed to answer all my questions. I knew after my first visit with him that he was the surgeon for me.

I would encourage anyone needing heart valve surgery to try to get in to see him. It may take some time but he is well worth the wait!"

"Dr. Unai is a gifted surgeon who specializes in complex cases. He is compassionate and has a reassuring presence. Not only did Dr. Unai repair my tricuspid valve, he also removed a mass from my atrium, which was consistent with a calcified thrombosis.

Dr. Unai met with me in the OR before my surgery started. He assured me that he and his team would take very good care of me, and that they did. I am fully recovered and feeling healthy and strong."
