Intraventricular Conduction Disturbances After Transcatheter Aortic Valve Implantation


Lin, Shu-I; Miura, Mizuki; Tagliari, Ana Paula; Lee, Ying-Hsian; Shirai, Shinichi; Puri, Rishi; Maisano, Francesco; Taramasso, Maurizio (2020). Intraventricular Conduction Disturbances After Transcatheter Aortic Valve Implantation. ICR Interventional cardiology, 15:e11.

Abstract

Despite significant improvements in transcatheter aortic valve implantation (TAVI) outcomes, periprocedural conduction disturbances, such as new-onset left bundle branch block (LBBB) and new pacemaker implantation (PMI), remain relatively frequent concerns. The development of periprocedural conduction disturbances can be explained by the proximity between the aortic valve and the conduction system. Although prior studies reported heterogeneity in PMI rates after TAVI, current evidence supports the potentially deleterious consequence of LBBB and PMI, and several predisposing factors have been reported. Therefore, new strategies to avoid conduction disturbances and to improve their management are required, particularly with the current trend to expand TAVI to a low-risk population.
