Surgical ablation improves rhythm control over repeat catheter ablation after failed PVI but increases serious adverse events; extends RCT data for ablation choice in recurrent AF.
Does surgical ablation reduce recurrence of atrial tachyarrhythmia compared to catheter ablation in patients with symptomatic AF after a failed initial pulmonary vein isolation?
In patients with failed initial catheter ablation for AF, surgical ablation is more effective than repeat catheter ablation for maintaining sinus rhythm, but carries a higher risk of serious adverse events.
