A wide complex tachycardia post-transcatheter aortic valve replacement

Abstract

BBR-VT is a unique macro–re-entrant VT that involves the right bundle, left bundle, and ventricular septum as part of the circuit. It should be in the differential diagnosis of patients undergoing TAVI procedure. This case demonstrates that some instances of post-TAVI BBRT may be transient and resolve without the need for permanent bundle branch ablation, which would otherwise necessitate conduction system pacing or cardiac resynchronization therapy. BBRT should be keep in mind patients undergoing TAVI procedures, and this case stress its transient apperance.
