心房颤动导管消融相关食管损伤的保护策略

Protective Strategies for Esophageal Injury Associated with Catheter Ablation of Atrial Fibrillation

导管消融已成为心房颤动的主要治疗手段之一,手术相关食管损伤是其常见的并发症,心房食管瘘虽罕见,但通常是致命的。本文主要综述了导管消融相关食管损伤发生率、损伤机制、危险因素及保护策略等,并指出更灵敏的食管温度监测、更安全的消融参数和导管、食管冷却及食管移位装置等均可降低食管热损伤发生风险。

Catheter ablation has become one of the main methods for the treatment of atrial fibrillation.Operationrelated esophageal injury is a common complication,and atrioesophageal fistulas are rare but usually fatal.This paper reviews the incidence,mechanism,risk factors and protection strategies of esophageal injury associated with catheter ablation.More sensitive esophageal temperature monitoring,safer ablation parameters and catheters,esophageal cooling,and esophageal displacement devices can reduce the risk of esophageal heat damage.
