Can we correct dyssynchrony by pacing the right side? The case for right ventricular–synchronized cardiac resynchronization therapy
Year: 2023
Type: article
Abstract: In heart failure with reduced ejection fraction (HFrEF) associated with left bundle branch block (LBBB) the benefits of cardiac resynchronization therapy (CRT) with coronary sinus lead and optimized device settings are universally recognized 1. His bundle pacing (HBP) and left bundle branch (LBBAP) pacing are emerging alternatives when LV placement in a coronary vein fails2,3. While there is some evidence showing electromechanical delays reduction by CRT in patients with RBBB associated with incomplete left fascicular delays [left anterior Hemiblock (LAH) or left posterior hemiblock (LPH)] and QRS > 150 ms, the efficacy of CRT in patients with right bundle branch block alone (RBBB) needs to be further elucidated, especially in the setting of conduction system pacing 4.
