Abstract

Left bundle branch area pacing (LBBAP) and left bundle branch–optimized cardiac resynchronization therapy (LOT-CRT) have emerged as alternative approaches to conventional biventricular pacing (BiVP) for CRT. Observational data from the international LBBAP collaborative study group demonstrated that LOT-CRT achieved greater electrical resynchronization than BiVP.1 In the CSPOT trial, LOT-CRT provided hemodynamic improvement comparable with BiVP, particularly among patients with advanced conduction disease.
