Feasibility of Left Bundle Branch Area Pacing via a Persistent Left Superior Vena Cava in a Patient with Repaired Ventricular Septal Defect

TL;DR

This paper shows that it's possible to perform a specific heart pacing procedure in a patient with a rare vein anomaly and a repaired heart defect.

Contribution

Demonstrates the feasibility of left bundle branch area pacing in a patient with PLSVC and repaired ventricular septal defect.

Findings

Left bundle branch area pacing was successfully performed in a patient with PLSVC.

The procedure was feasible despite prior congenital heart surgery.

This case expands the understanding of CSP in complex anatomical scenarios.

Abstract

Persistent left superior vena cava (PLSVC) is the most common systemic venous anomaly and may complicate cardiac device implantation, particularly in patients with a history of congenital heart surgery. We report the case of a 16-year-old girl with a surgically repaired ventricular septal defect who developed complete heart block, necessitating conduction system pacing (CSP). This case highlights the feasibility of CSP in the presence of PLSVC and prior congenital heart surgery.
