Dr.Wazni was very courteous, very clear; however, he really did not come across as someone who really had a whole lot of true sympathy or care. Possibly that is his nature. Either way, we chose him because of his expertise and not his personality.

After my visit a test was ordered to determine further treatment. I am still waiting to have the test results explained and to determine what should be done.

Reviewed on Jan 17, 2023

Originally, I thought I was supposed to see Dr. Wazni in October or November, but when I called I found that nothing had been scheduled but they quickly got me scheduled for January. Also Dr. Wazni ordered a Zio for me to wear for two weeks in late November, so he had the Zio data as well as an Echo and EKG before I saw him.

Reviewed on Jan 17, 2023

My results were very good, so no treatments or added medicines were needed. Dr. Wazni did tell me that he would see me in one year.

Dr Wazni's and his office provided excellent care and service. He and his team are absolutely number one! The only downfall was having to wait ten weeks for my cardiac ablation. I feel that long of a wait contributed to scarring of my heart and making my ablation so extensive.

Cardiologist showed empathy and yet was very professional and to the point. Lacking certain data from my previous provider, he quickly put together a plan that gave me comfort as a new patient going forward. I developed trust and confidence very quickly with his skill.

Dr. Wazni is fantastic.

Reviewed on Aug 18, 2022

I have a great deal of respect for Dr Wazni, his skill and reputation but this last visit seemed like he was simply shrugging his shoulders and telling me it is what it Is and didn't seem to offer any hope or opportunity for progress or healing.

Reviewed on Aug 16, 2022

Dr. Wazni is my Physician and he is treating me for Afib. He is an amazing physician who is absolutely dedicated to what is best for the patient. I would recommend him without reservation to anyone with heart rhythm problems. I came to Cleveland to have an ablation for my Afib. After my work up and evaluation over several days, he suggested to me that I may benefit from waiting to have the procedure, as a higher dose of my medication was keeping me in control. Most physicians today are volume and revenue focused and it is unusual for a doctor to postpone a scheduled procedure. Dr. Wazni is focused only on doing the right thing. I truly feel I am in great hands with Dr. Wazni.

My only complaint is that I ended up having a little bit of a shorter visit with my doctor because he was behind he was amazing all the way around so no complaint there I do feel like I have a lot of questions now or shortly after my visit just due to the overwhelm of the information I was given about my care

Excellent experience. Dr. Wazni's thoroughness in review of the Interview Nurse notes and Dr. Johnson's notes from 2014 surgery eliminated the need for the Watchman. Also recommendation for TEE exam followed up and blood thinners have been discontinued.
