Increased rates of atrial fibrillation recurrence following pulmonary vein isolation in overweight and obese patients

Catheter ablation is common for patients with symptomatic, drug‐refractory atrial fibrillation (AF). Obesity is a known risk factor for incident AF. The impact of obesity on AF ablation outcomes is incompletely understood. We sought to determine the impact of elevated body mass index (BMI) on pulmonary vein isolation (PVI) procedural outcomes and associated complications.
