CRT Likely Benefits Broader Group of Patients: Meta-analysis

Among patients with a wide QRS, cardiac resynchronization therapy (CRT) seems to help patients with an intraventricular conduction delay (IVCD) as much as it does those with left bundle branch block ...

Conduction System Pacing Falls Short of Biventricular Pacing in HFrEF With LBBB

A 173-patient randomized trial in HFrEF (LVEF ≤35%) with LBBB (QRS ≥130 ms) showed CSP was inferior to BiVP for a hierarchical 12‑month composite endpoint. Worse outcomes with CSP were reflected by an ...

Left Bundle-Branch Pacing Reduces Heart Failure Hospitalization vs Biventricular Pacing

Multicenter randomized trial (n=200) assigned LBBP versus BiVP for CRT in LBBB with LVEF ≤35%, using time to death or HF hospitalization as primary endpoint. Event rates favored LBBP, reducing death ...
