Catheter ablation of atrial fibrillation.

Atrial fibrillation, the most common cardiac arrhythmia requiring treatment, has significant morbidity and mortality consequences. Pharmacologic therapy consisting of anticoagulants, AV nodal blocking agents and antiarrhythmics, remain the primary treatment. However, several nonpharmacologic therapies for the treatment of atrial fibrillation have been developed. In this review, we provide a detailed discussion of the most promising nonpharmacologic approach to the treatment of atrial fibrillation-catheter-based ablation.
