Abstract
Background: Left bundle branch area pacing (LBBAP) offers
physiological pacing with potential advantages over right ventricular
(RV) pacing, particularly in children. However, data on LBBAP in
pediatric populations are scarce. Objective: This study aimed
to assess the feasibility and safety of LBBAP in children by reporting 6
cases done successfully. Methods: Six children (four males, two
females), aged 2 to 16 years, underwent LBBAP between December 2022 and
January 2024 at the American Univeristy of Beirut Medical Center
(AUBMC). The implantation procedure followed established techniques.
Baseline characteristics, echocardiographic measurements, and pacing
parameters were recorded. Results: All six cases fulfilled the
criteria for LBBAP. Successful LBBAP was achieved in all cases. Median
weight is 20.5 kg, with three patients under 5 years old. Baseline left
ventricular ejection fraction (LVEF) was normal in 4 cases, with two
exhibiting 52%. The interventricular septal thickness averaged 4.5 mm.
No major complications were encountered during follow-up.
Conclusion: Left bundle branch area pacing might be a promising
alternative to conventional RV pacing, offering potential advantages
over traditional pacing methods. Further research is needed to fully
elucidate its efficacy and long-term benefits in pediatric populations.
