Key result
Left bundle branch area pacing was feasible and safe in pediatric patients, with no reported procedure-related complications and stable pacing parameters during follow-up up to 2 years.
Why the study?
The feasibility and safety of left bundle branch area pacing in pediatric patients with atrioventricular block have not been well demonstrated, with published reports limited to 3 months to 1 year follow-up.
Does left bundle branch area pacing (LBBAP) provide safe and stable physiological pacing in pediatric patients with high-degree atrioventricular block?

LBBAP appears to be a feasible and safe alternative physiological pacing modality for pediatric patients with AVB, demonstrating stable electrical parameters and preserved ventricular function over a 2-year follow-up.
The feasibility and safety of left bundle branch area pacing (LBBAP) used in pediatric patients with atrioventricular block (AVB) have not been well demonstrated. Currently, only several case reports for pediatric patients have been published since the advent of LBBAP, with 3 months to 1 year follow-up. Here, we present a case of LBBAP in a 6-year-old child with a high-degree AVB secondary to the transcatheter device closure of congenital ventricular septal defect. No procedure-related complications were observed, and the electrical parameters were stable at 2-year follow-up. Additionally, we performed a systematic literature review on pediatric patients with LBBAP. Fifteen cases were retrieved after systematically searching PubMed and Embase databases. No complications have been reported among these published cases. In conclusion, consistent with previous cases, our case with 2-year follow-up has demonstrated that LBBAP may be an alternative pacing modality from a very early age. However, given the limited evidence, the long-term outcomes of LBBAP in pediatric patients should be further investigated.

Hua et al. (2022) conducted a case report in High-degree atrioventricular block (n=16). Left bundle branch area pacing (LBBAP) was evaluated on Procedure-related complications and pacing parameter stability. Left bundle branch area pacing was feasible and safe in pediatric patients, with no reported procedure-related complications and stable pacing parameters during follow-up up to 2 years.
