Why the study?
Pediatric patients with complete congenital AV block typically face life-long dyssynchronous RV pacing, whereas His bundle pacing may better restore physiological ventricular activation and prevent pacing-induced cardiomyopathy.
Is permanent His bundle pacing guided by 3D electro-anatomical mapping feasible and safe in a young child with complete AV block?

Permanent His bundle pacing guided by 3D electro-anatomical mapping is feasible in young children with complete AV block, offering a potential alternative to dyssynchronous right ventricular pacing.
Pediatric patients with complete congenital atrio-ventricular (AV) block are generally exposed to life-long dyssynchronous right ventricular (RV) pacing. His bundle pacing (HBP) is an alternative method of pacing that better restores physiological ventricular activation which could prevent pacing-induced cardiomyopathy. We present a case of a 5-year-old child with complete AV block who underwent successful permanent HBP implantation. Three-dimensional electro-anatomical mapping system was used to facilitate the procedure and reduce the fluoroscopy time. There were no acute procedure-related complications, and electrical parameters were stable at short-term follow-up.
