Conduction disturbances (CDs) are common after transcatheter aortic valve replacement. Continuous improvements in preprocedural planification, implant techniques, and device design have markedly reduced periprocedural complications. However, CDs rate remains in the double-digit range. Because CDs after TAVR are associated with poorer outcomes, seeking a reduction in their occurrence is paramount. Several nonmodifiable and modifiable factors are associated with an increased risk of CDs. Previous right bundle branch block has been shown to have a strong association with pacemaker implant after TAVR. Among the modifiable factors, a lower implantation depth seems to be associated with a higher risk of CDs, and several implant strategies aiming to obtain a higher implant depth have shown promising results. This literature review provides a detailed description of updated evidence about the epidemiology, impact, and preventive and management strategies of CDs after TAVR. Also, based on these updated data, a fast-track protocol CDs management is proposed.

经导管主动脉瓣置换术后传导障碍：流行病学、预防策略和管理的最新信息。


经导管主动脉瓣置换术后传导障碍 （CDs） 很常见。术前平面化、植入技术和装置设计的持续改进显着减少了围手术期并发症。但是，CD 利率仍处于两位数范围内。由于 TAVR 后的 CD 与较差的结局相关，因此寻求减少其发生率至关重要。一些不可改变和可改变的因素与 CD 风险增加有关。先前的右束支传导阻滞已被证明与 TAVR 后起搏器植入物有很强的相关性。在可改变的因素中，较低的植入深度似乎与较高的 CDs 风险相关，并且几种旨在获得更高植入深度的植入策略已显示出有希望的结果。本文献综述详细描述了有关 TAVR 后 CDs 的流行病学、影响以及预防和管理策略的最新证据。此外，基于这些更新的数据，提出了一种快速通道协议 CDs 管理。
