Left Bundle Branch Pacing: A Safe and Effective Alternative for Cardiac Resynchronization

Abstract

Background: Left bundle branch pacing (LBBP) is an emerging pacing strategy aimed at providing physiological cardiac resynchronization and maintaining ventricular function. This study evaluates the clinical efficacy, safety, and stability of LBBP in a cohort of patients over a 6-month follow-up. Methods: This prospective study included patients undergoing left bundle branch pacing (LBBP) over an 18-month period, commencing in June 2023. Patients undergoing LBBP were assessed for demographic characteristics, comorbidities, and clinical outcomes. Left ventricular ejection fraction (LVEF) and pacing capture thresholds were measured at baseline, 3 months, and 6 months. Complications, including lead displacement, capture threshold increases, and pocket infections, were recorded during follow-up.
