摘　　要：射频导管消融是心力衰竭合并房颤及症状性房颤的首选治疗方案,环肺静脉隔离是房颤导管消融治疗的基石。解剖位置上食管毗邻左心房后壁,因此,左心房后壁消融时有发生食管损伤的风险,严重时会引起致命性的心房食管瘘。如何降低房颤消融术后食管损伤的发生率已成为目前临床关注的重要问题。现总结国内外关于消融指数指导下高功率短时程与低功率长时程消融对房颤射频消融中食管损伤的差异,为减少房颤导管消融食管损伤提供依据。Radiofrequency catheter ablation is the preferred treatment for heart failure complicated with atrial fibrillation and symptomatic atrial fibrillation.Circumferential pulmonary vein isolation is the cornerstone of catheter ablation for atrial fibrillation.Due to the anatomical location of the esophagus was adjacent to the posterior wall of the left atrium,ablation of the posterior wall of the left atrium is associated with the risk of esophageal injury and,in severe cases,developed into fatal atrio-esophageal fistula.How to reduce the incidence of esophageal injury after atrial fibrillation ablation has become an important clinical concern.This review summarized the differences between high-power short-duration ablation and low-power long-duration ablation guided by ablation index on esophageal injury in atrial fibrillation radiofrequency ablation,providing evidence for reducing the incidence of esophageal injury in atrial fibrillation radiofrequency ablation.
