The interaction was extremely positive, informative, shaped my care path going forward, and addressed the risk/reward continuum. While medicine is a science, it is not an exact science yet, with inherent risks. I clearly understand the risks and why moving forward with an ablation Is the best option for me. There is still an art to effective patient interactions. Dr. Wazni is one of the best doctors i''ve interacted with. I''m confident in his recommendations.

Dr. Wazni spent about 25 min. Patiently answering our questions. Coached us with odds, statistics and research facts rather than opinions. Was honest about CC's long lead times for ablation. I was very glad I drove 3 hours each way to meet with him.
