Key result
Additional ablation of continuous CFEs after PVI and linear ablation achieved a procedural AF termination rate of 53% and a higher rate of long-term sinus rhythm maintenance.
Why the study?
Does additional ablation of complex fractionated atrial electrograms improve sinus rhythm maintenance in patients with nonparoxysmal atrial fibrillation undergoing PVI and linear ablation?

May support adjunctive continuous CFE ablation in nonparoxysmal AF; hypothesis-generating and requires randomized confirmation.
Lin et al. (2009) conducted a cohort in Nonparoxysmal atrial fibrillation (n=60). Pulmonary vein isolation (PVI) plus linear ablation with additional ablation of complex fractionated atrial electrograms (CFEs) vs. PVI plus linear ablation without additional ablation of CFEs was evaluated on Sinus rhythm maintenance. Additional ablation of continuous CFEs after PVI and linear ablation achieved a procedural AF termination rate of 53% and a higher rate of long-term sinus rhythm maintenance.
