The cardiology department and Dr. Zadir were head and shoulders above the cardiologist I had been seeing in Indiana. Absolutely worth the effort to travel to the Cleveland clinic. I cannot recommend highly enough.

Dr Zidar was fantastic! I''m not a fan of the team approach in general. Why is it necessary to talk to 3 different cardiologists, not including Dr Zidar who performed the catherization, and deal with getting information from 3 different nurse practitioners?
