An internationally known pioneer and inventor, Dr. Avitall’s holds numerous patents in cardiac arrhythmia ablation and has published extensively on the subject. The one of the first researcher to test endocardial atrial fibrillation ablation, he introduced linear ablation technology to the field of atrial fibrillation ablation. He also co-invented and was the first to examine the applicability of cryoballoon technology to the treatment of atrial fibrillation, which led to this technology becoming a commonly used approach to ablate atrial fibrillation. Dr. Avitall has done extensive work on the long-term harmful impact of chronic atrial fibrillation and continue to innovate and test new technologies.
