Why the study?
Conduction system damage is the most common complication of TAVR and can create a substrate for both advanced atrioventricular block and bundle branch reentry ventricular tachycardia, requiring discussion of the potential risks, diagnosis, and management of BBR after TAVR.

Conduction system damage is the most common complication of transcatheter aortic valve replacement (TAVR), which frequently requires placement of a permanent pacemaker. Bundle branch reentry (BBR) is a well-recognized mechanism of ventricular tachycardia (VT) in the setting of abnormal intraventricular conduction. We describe a case of a patient with post-TAVR intraventricular conduction abnormalities who presented with intermittent advanced atrioventricular block and BBR VT and discuss the potential risks, diagnosis, and management of BBR after TAVR.

Kocherla et al. (2020) conducted a case report in Bundle branch reentry ventricular tachycardia and intermittent advanced atrioventricular block following transcatheter aortic valve replacement (TAVR) (n=1). Right bundle branch catheter ablation was evaluated on Freedom from inducible ventricular tachycardia and recurrent syncope/arrhythmia.
