Adjunctive ablation strategies improve the efficacy of pulmonary vein isolation in non-paroxysmal atrial fibrillation: a systematic review and meta-analysis.

Background: Pulmonary vein (PV) isolation (PVI) has suboptimal outcomes in patients with non-paroxysmal atrial fibrillation (AF). Adjunctive strategies employed to ablate non-PV triggers have shown favorable outcomes.

Aims: To delineate the incremental benefit of adjunctive ablation in patients with non-paroxysmal AF through a meta-analysis.
