Cardiac resynchronization therapy-defibrillator implantation with shock lead placement in the left bundle branch area: a case report.

ABSTRACT:

Background

Cardiac resynchronization therapy (CRT) with biventricular pacing is a well-established therapy. Left bundle branch area pacing (LBBAP) is a safe technique providing physiological pacing, and LBBAP-optimized CRT (LOT-CRT) has been shown to provide better electrical resynchronization than traditional CRT. However, there are few reports on shock lead placement in the left bundle branch area (LBBA) during CRT-defibrillator (CRT-D) implantation.

Case summary

A 76-year-old woman with heart failure from dilated cardiomyopathy presented with left bundle branch block pattern (QRS duration, 160 ms). Left ventricular ejection fraction was 21%. Cardiac resynchronization therapy-defibrillator implantation was performed due to worsening symptoms. By reshaping the Agilis HisPro
