Key result
Right bundle branch ablation successfully treated incessant ventricular tachycardia suspected to be bundle branch reentrant ventricular tachycardia in a young man post-aortic valve replacement.
Case Report (n=1)
Right bundle branch ablation can successfully treat suspected bundle branch reentrant ventricular tachycardia presenting as incessant VT and cardiogenic shock following aortic valve replacement.
IABP resolved refractory post-AVR VT in one case; leaves open any role for mechanical support in managing surgical arrhythmias.
We present the case of a young man who suffered from severe aortic valve insufficiency and subsequently underwent mechanical aortic prosthesis replacement. One month post-surgery, he presented with syncope and incessant ventricular tachycardia (VT), progressing to cardiogenic shock, which required emergency intra-aortic balloon pump (IABP) support. The VT proved refractory to standard clinical management and demonstrated responsiveness only after IABP support. An electrophysiological study was conducted; however, VT could not be induced during the procedure. Through electrophysiological maneuvers, we suspected bundle branch reentrant ventricular tachycardia (BBR-VT), and successful treatment was achieved via right bundle branch (RBB) ablation.

Coello et al. (2025) conducted a case report in Incessant ventricular tachycardia post-aortic valve replacement (n=1). Right bundle branch (RBB) ablation was evaluated on Successful treatment of ventricular tachycardia. Right bundle branch ablation successfully treated incessant ventricular tachycardia suspected to be bundle branch reentrant ventricular tachycardia in a young man post-aortic valve replacement.
