心脏传导异常和（或）房室传导阻滞是经导管主动脉瓣植入（TAVI）术后常见的并发症之一。房室传导阻滞源于人工瓣膜假体对传导系统的损伤。主动脉瓣狭窄患者接受TAVI术前存在右束支传导阻滞（RBBB）、采用自膨胀式美敦力CoreValve系统（MCRS）以及瓣膜假体植入左室流出道过深均被认为是术后需要永久性心脏起搏治疗的相关因素。
心髒傳導異常和（或）房室傳導阻滯是經導管主動脈瓣植入（TAVI）術後常見的併髮癥之一。房室傳導阻滯源于人工瓣膜假體對傳導繫統的損傷。主動脈瓣狹窄患者接受TAVI術前存在右束支傳導阻滯（RBBB）、採用自膨脹式美敦力CoreValve繫統（MCRS）以及瓣膜假體植入左室流齣道過深均被認為是術後需要永久性心髒起搏治療的相關因素。

Cardiac conduction abnormalities and/or atrioventricular (AV) block have been reported as one of the most frequent complications of transcatheter aortic valve implantation (TAVI). The impairment of AV conduction was resulted from the balloon and valve-induced injury. Patients with right bundle branch block (RBBB) before TAVI operation, receiving the Medtronic CoreValve Revalving System (MCRS) implant and the implantation of valve prosthesis too deep in the left ven-tricular outflow tract have been reported to require permanent pacemaker implantation.
