Atrial fibrillation (AF) contributes to considerable morbidity, with increasing risk of stroke, complications from anticoagulation, and exacerbation of heart failure. AF ablation has become a commonly performed procedure in many hospitals as the procedural techniques evolve rapidly with improved success. Here we discuss the interventional options of catheter-based AF ablation for rhythm control, which offers the benefit of mortality reduction associated with normal sinus rhythm but without medication complications.
