Permanent Left Bundle Branch Area Pacing for High-Degree Atrioventricular Block in a 6-Year-Old Child with 2-Year...

Area of Science:

• Cardiology
• Pediatric Electrophysiology
• Medical Devices

Background:

• Limited data exists on the safety and feasibility of left bundle branch area pacing (LBBAP) in pediatric patients with atrioventricular block (AVB).
• Existing literature primarily consists of case reports with short-term follow-up periods (3 months to 1 year).

Observation:

• A 6-year-old child with high-degree AVB, secondary to transcatheter device closure of a congenital ventricular septal defect, underwent successful LBBAP.
• The patient experienced no procedure-related complications, and pacing parameters remained stable throughout the 2-year follow-up period.
• A systematic literature review identified 15 pediatric cases of LBBAP, with no reported complications.

Findings:

• Left bundle branch area pacing (LBBAP) demonstrated feasibility and safety in a pediatric case with a 2-year follow-up.
• The systematic review of 15 pediatric cases revealed no reported complications associated with LBBAP.
• Electrical parameters remained stable, indicating the long-term efficacy of LBBAP in this pediatric population.

Implications:

• Left bundle branch area pacing (LBBAP) may serve as a viable alternative pacing strategy for pediatric patients, even from a very young age.
• Further research is warranted to investigate the long-term outcomes and establish LBBAP as a standard pacing modality in children.
• The findings support the consideration of LBBAP in pediatric cases of atrioventricular block, pending more extensive long-term data.
