经导管二尖瓣缘对缘修复术的并发症及处理

Complications and management of transcatheter edge-to-edge mitral valve repair

二尖瓣反流的发病率和病死率较高,经导管二尖瓣缘对缘修复术(transcatheter edge-to-edge mitral valve repair,TEER)的应用使得原发性和继发性二尖瓣反流的治疗有了更多的选择。随着术者经验的累积、设备的改进及术中影像学的优化,TEER得以应用于更为复杂或危重的患者。TEER相关不良事件的发生率较低,但可能发生的一些并发症有潜在的危险。TEER相关并发症及其处理方法是手术安全起效的保障,该文探讨了TEER可能出现的主要并发症以及相应的处理策略。

Mitral regurgitation has high morbidity and mortality.The application of transcatheter edge-to-edge mitral valve repair(TEER)has provided more options for the management of primary and secondary mitral regurgitation.With the accumulation of operator experience,the improvement of equipment,and the optimization of intraoperative imaging,TEER can be applied to more complex or critically ill patients.The incidence of TEER-related adverse events is low,but some complications that may occur are potentially dangerous.TEER-related complications and their treatment methods are the guarantee of safe and effective operation.This article discusses the main possible complications of TEER and the corresponding management strategies.
