Complications of Atrial Fibrillation Ablation in a High‐Volume Center in 1,000 Procedures: Still Cause for Concern?

Catheter ablation is potentially curative treatment for atrial fibrillation (AF). However, complications are more frequent and more severe compared with other ablation procedures. We investigated the complication rate in 1,000 AF ablation procedures in a high-volume center and examined possible risk factors.One thousand consecutive circumferential pulmonary vein radiofrequency ablations were performed for symptomatic, drug-refractory AF. Major...
