High rate of bradycardia-dependent left bundle branch block after transcatheter aortic valve implantation

HeartRhythm

Left bundle branch block (LBBB) is a frequent complication of transcatheter aortic valve implantation (TAVI) and was shown to predict advanced atrio-ventricular block and pacemaker implantation (PI).1,2 1,2 Previous studies focused on persistent TAVI-induced LBBB. There are limited data on TAVI-related intermittent LBBB.
