Left bundle branch area pacing: A new era of cardiac resynchronization therapy?

World J Cardiol. 2024 Sep 26;16(9):542-545. doi: 10.4330/wjc.v16.i9.542.

Abstract

The recent systematic review and meta-analysis provided a comprehensive focus on the current state of cardiac resynchronization therapy (CRT). The authors determined the feasibility of physiological left bundle branch area pacing (LBBAP) in patients indicated for CRT through a careful analysis of trials. They found that LBBAP was associated with significant reductions in QRS duration, New York Heart Association functional class, B-type natriuretic peptide levels, and pacing thresholds as well as improvements in echocardiographic parameters compared to biventricular pacing.
