Description
This observational study included patients with LVEF≤35% who underwent biventricular or left bundle area pacing for the first time for Class I or II indications at 15 international centers. The primary outcome was the composite endpoint of time to death or heart failure hospitalization. Secondary outcomes included endpoints of death, HFH, and echocardiographic changes. Following implantation, LVEF improved from 27 to 41% with left bundle area pacing compared to an increase from 27 to 37% with biventricular pacing. On multivariable regression analysis, the primary outcome was significantly reduced with left bundle area pacing compared to biventricular pacing (20.8% vs 28%). The authors conclude that left bundle area pacing improved clinical outcomes, as observed in this study.
Learning Objectives
- To review the relevant findings of the Comparison of Left Bundle-Branch Area Pacing to Biventricular Pacing in Candidates for Resynchronization Therapy recently present at HRS.
