Left Atrial Diameter as a Risk Factor for Atrial Fibrillation Recurrence After Surgical Ablation: A Systematic Review and Meta-analysis

1. Abstract

1.1. Background: Surgical Ablation (SA) is widely performed to eliminate Atrial Fibrillation (AF) and maintain atrial contraction. A larger Left Atrial Diameter (LAD) has long been associated with the late recurrence of AF post-ablation.

1.2. Objectives: We conducted a meta-analysis to assess the relationship between LAD and AF recurrence after SA and investigated the effect of LAD cut-off values on the probability of AF recurrence via subgroup analysis.
