Catheter ablation of atrial fibrillation (AF) became an effective therapy for patients with drug-refractory AF, and the indications have broadened to include nonparoxysmal AF patients. However, data about the long-term effectiveness of ablation in patients with nonparoxysmal AF are lacking. The aim of the present study was to investigate the long-term outcomes of catheter ablation in patients with nonparoxysmal AF.

Methods and Results—A total of 88 nonparoxysmal AF patients who received a stepwise catheter ablation (isolation of the pulmonary veins plus substrate modification) from 2006 to 2008 were enrolled. Freedom of recurrence was defined as the absence of atrial arrhythmias without using any antiarrhythmic agents after the catheter ablation.  Read more
