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.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Cardiac Cycle
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...
