Implantation of Leadless Pacemaker for the Development of New Left Bundle Branch Block and Symptomatic Pause Following Transcatheter Aortic Valve Replacement.

Author information

Department of Cardiovascular Diseases, Mayo Clinic, Rochester, MN, USA.


Cardiac conduction disturbances such as left bundle branch block (LBBB) and atrioventricular blocks (AVB) occur frequently following transcatheter aortic valve replacement (TAVR) and may be associated with adverse clinical events. There is a lack of consensus regarding permanent pacemaker implantation in the case of occurrence of TAVR-related bundle branch blocks or combination of AVB and bundle blocks. Furthermore, there are no guidelines regarding the use of the leadless pacemaker in this setting. We present a patient who underwent successful implantation of a leadless pacemaker for a new LBBB post-TAVR.
