经导管主动脉瓣植入术后的起搏器植入

Permanent Pacemaker Implantation after Transcatheter Aortic Valve Implantation

经导管主动脉瓣植入术通过股动脉途径,将人工生物瓣膜支架送至狭窄的主动脉瓣区,以自膨胀或球囊膨胀的方式打开,主要用于治疗不能耐受外科换瓣手术的重度钙化性的主动脉瓣狭窄。经导管主动脉瓣植入术后最主要的并发症之一包括心脏传导阻滞,部分患者需要永久起搏器的植入来改善预后。然而,在经导管主动脉瓣植入术后起搏器植入的预测因素、植入指征、植入时机等多个方面仍存在很多争议。现主要归纳总结经导管主动脉瓣植入术后起搏器植入的研究进展,以促进人们对此领域的认识。

The transcatheter aortic valve implantation（TAVI） delivers a artificial valve to the aortic valve＇s place,wbich provides a treatment for the inoperable patients with severe, calcific, symptomatic aortic stenosis. Heart block was considered to be the most important complieation associated with TAVI. Some of the patients who suffered from the heart block after TAVI had the requirement for the permanent pacemaker implantation. However, there were conversely opinions in the predictors , timing and indication of permanent pacemaker implantation. This review briefly summarizes recent advances in the research on permanent pacemaker implantation after TAVI.
