The efficacy of intraoperative atrial radiofrequency ablation for atrial fibrillation during concomitant cardiac surgery—the Surgical Atrial Fibrillation Suppression (SAFS) Study

Introduction Studies assessing radiofrequency ablation (RFA) for atrial fibrillation (AF) performed at the time of concomitant cardiac surgery have reported high success rates. The efficacy of this treatment has primarily been determined by a single electrocardiogram (ECG) or 24-h Holter monitor at follow-up. We sought to assess the true efficacy of this procedure using prolonged cardiac rhythm monitoring.
