Unique transvenous approach achieves LBBP in a 14-year-old with AV block and corrected Ebstein anomaly.
Case Report (n=1)
Demonstrates the feasibility of a novel transvenous approach for left bundle branch pacing in a post-Glenn patient with a bioprosthetic tricuspid valve.
Suggests a viable alternative in post-Glenn patients with limited access; leaves open safety and reproducibility in larger cohorts.
We report a 14-year-old female with a history of surgically corrected Ebstein anomaly, including a bidirectional Glenn shunt and atrial septostomy. Following a bioprosthetic tricuspid valve replacement, the patient developed complete atrioventricular block and became pacemaker-dependent. A unique transvenous approach was utilized: the ventricular lead was advanced from the left axillary vein through the left subclavian vein, superior vena cava, right pulmonary artery, and main pulmonary artery into the right ventricle, resulting in successful left bundle branch pacing. This case illustrates an innovative strategy for permanent physiological pacing in post-Glenn patients.

Huang et al. (2026) conducted a case report in Complete atrioventricular block in post-Glenn Ebstein's anomaly (n=1). Left bundle branch pacing via a unique transvenous approach was evaluated on Successful left bundle branch pacing. A unique transvenous approach successfully achieved left bundle branch pacing in a 14-year-old female with complete AV block and a history of surgically corrected Ebstein anomaly.
