A Extensão das Lesões de Ablação no Átrio Esquerdo e a Recorrência de Fibrilação Atrial após Ablação por Cateter – Uma Revisão Sistemática e Metanálise

Background: Atrial fibrillation (AF) is known to induce atrial remodeling, which promotes fibrosis related to arrhythmogenesis. Accordingly, since scars induced by catheter ablation (CA) can reduce unablated fibrotic areas, greater extent of left atrial (LA) scarring may be associated with less AF recurrence after CA. Objectives: This study aims to investigate, through systematic review and meta-analysis, whether the amount of LA scarring, seen...
