Left Bundle Branch Pacing Versus Biventricular Pacing for Acute Cardiac Resynchronization in Patients With Heart Failure.

ABSTRACT:

Background

Left bundle branch pacing (LBBP) has emerged as an alternative to biventricular pacing (BVP) for delivering cardiac resynchronization therapy. We sought to compare the acute improvement of electrical and mechanical synchrony, and hemodynamics between LBBP and BVP in patients with heart failure and left bundle branch block.

Methods

LBBP and BVP were performed and compared in a crossover fashion in patients with heart failure and left bundle branch block undergoing cardiac resynchronization therapy implantation. Electrical synchrony was assessed by QRS duration and area, mechanical synchrony by the SD of time to peak velocity of 12 left ventricular segments (Ts-SD) and interventricular mechanical delay, and hemodynamics by the maximum rate of left ventricular pressu
