Transcatheteraortic valve replacement (TAVR) is a revolutionized treatment for severe aortic valve stenosis. Although new and improved TAVR devices are constantly being developed, cardiac conduction abnormalities post-TAVR requiring permanent pace14353maker implantation (PPMI) still occur frequently. Previously, pre-existing right bundle branch block (RBBB) has been shown to be predictive of PPMI after TAVR compared with patients without RBBB, while occurrence of new left bundle branch block (LBBB) was associated with a higher rate of PPMI. However, less attention has been paid to the clinical values of new onset non-LBBB conduction disturbances such as RBBB, left anterior fascicular block (LAFB) or atrioventricular block (AVB). To our knowledge, this is the first report focus on the association of new-onset non-LBBB and PPMI after TAVR. The study was approved by the Ethics Committee of HwaMei Hospital, University of Chinese Academy of Sciences.

经导管主动脉瓣置换术后非左束支传导阻滞的结果

经导管主动脉瓣置换术 (TAVR) 是治疗严重主动脉瓣狭窄的革命性疗法。尽管不断开发新的和改进的 TAVR 设备，但需要永久起搏器植入 (PPMI) 的 TAVR 后心脏传导异常仍然经常发生。以前，与没有 RBBB 的患者相比，预先存在的右束支传导阻滞 (RBBB) 已被证明可以预测 TAVR 后的 PPMI，而新的左束支传导阻滞 (LBBB) 的发生与更高的 PPMI 发生率相关。然而，对新发非 LBBB 传导障碍如 RBBB、左前束支传导阻滞 (LAFB) 或房室传导阻滞 (AVB) 的临床价值关注较少。据我们所知，这是第一份关注 TAVR 后新发非 LBBB 与 PPMI 关联的报告。
