Junctional Rhythm Following Transcatheter Aortic Valve Replacement

Transcatheter aortic valve replacement (TAVR) has rapidly evolved as a treatment alternative to surgical aortic valve replacement for patients with symptomatic severe aortic stenosis with moderate or high surgical risk.1,2 With the recent FDA decision to expand its indication to low-risk patients, TAVR is expected to be the primary option for aortic valve replacement in the future.3 However, TAVR is associated with injury to the conduction system at the level of the bundle of His and the left bundle branch, leading to permanent pacemaker (PPM) implantation for complete atrioventricular (AV) block.
