Conversion from cardiac resynchronization therapy to left bundle branch area pacing in a child with congenital heart disease and pacing-induced cardiomyopathy: A case report

Year: 2026

Type: article

Abstract: Conduction system pacing (CSP), including left bundle branch area pacing (LBBAP), is recognized as an alternative to conventional right ventricular pacing, aiming to mitigate pacing-induced cardiomyopathy (PICM) by minimizing ventricular dyssynchrony.[1] We present a pediatric case of congenital heart disease (CHD) with PICM, previously managed with cardiac resynchronization therapy (CRT), who was successfully converted to LBBAP. After the procedure, the patient demonstrated significant improvement in electrocardiographic and echocardiographic indices of ventricular function.
