Clinical Outcome of Catheter Ablation in Patients With Nonparoxysmal Atrial Fibrillation

Abstract

The long-term recurrence-free rate of ablation in nonparoxysmal AF was only 28.4% after a single procedure, and multiple procedures were necessary to raise the recurrence-free rate. The CHADS2 score and LA dimension may help us to identify patients who will have recurrences after catheter ablations of nonparoxysmal AF.
