经导管二尖瓣缘对缘修复术的术中操作要点

Key procedural techniques for transcatheter mitral valve edge-to-edge repair

经导管二尖瓣缘对缘修复术(transcatheter mitral valve edge-to-edge repair,TEER)已成为外科手术高危的重度二尖瓣反流患者的重要治疗选择,然而该手术器械和操作流程均较复杂,国内目前尚缺乏标准化的TEER操作流程。基于现有循证医学证据以及术者在临床实践中积累的经验,该文简要介绍了TEER的定义、适应证、禁忌证以及手术器械,并对手术流程、技术操作要点、并发症及其处理措施进行了系统而详尽的阐述,为TEER在我国临床实践中规范开展和推广普及提供指导。

Transcatheter mitral valve edge-to-edge repair(TEER)has become an essential treatment option for patients with severe mitral regurgitation at high or prohibitive surgical risk.However,the surgical devices and procedural steps of the surgery are intricate,and there is currently a lack of standardized TEER procedures in China.Based on existing evidence and the accumulated experience in clinical practice,this article briefly introduces the definition,indications,contraindications,and surgical devices of TEER.It also provides a systematic and detailed elaboration on the procedural steps,key technical points,complications,and their management measures,offering guidance for the standardized implementation and widespread adoption of TEER in clinical practice in China.
