Outcomes of persistent and long-standing persistent atrial fibrillation ablation: a systematic review and meta-analysis

AimsSeveral techniques have been utilized for the ablation of persistent (P) and long-standing persistent (LsP) atrial fibrillation (AF); however, the best approach of substrate ablation remains poorly defined. This study aims to examine the impact of ablation approach on outcomes associated with P or LsP AF ablation by conducting a meta-analysis and regression on contemporary literature.
