Catheter Ablation for Atrial Fibrillation 

This Harvard Medical School Continuing Education video examines these key questions: Who is an appropriate candidate for atrial fibrillation and which methods are most successful? Why do the definitions of ablation success vary across patient populations?
Dr. William Hucker, MD, PhD, a cardiologist at Massachusetts General Hospital, reviews pharmacological and nonpharmacological methods of achieving rhythm control and identifies the best strategies for patients, with a focus on evidence-based studies. Pulmonary vein isolation is discussed as well as efficacy endpoints.
