Left Bundle Branch Pacing in a Pediatric Patient With Tricuspid Valve Replacement for a Complex Ebstein Anomaly.

This paper presents a unique case of successful implementation of left bundle branch pacing (LBBP) in a pediatric patient with third-degree atrioventricular block following tricuspid valve replacement for a complex Ebstein anomaly. The procedure was performed under real-time recording technique, and resulted in the resolution of the patient's symptoms. This case underscores the feasibility and potential benefits of LBBP in pediatric patients, particularly in those with complex congenital heart conditions and following valve replacement surgery. The successful implementation of LBBP in this case provides valuable insights and a reference for similar cases in the future.
