Is epicardial dual-chamber physiological pacing feasible in a 2-year-old child with postoperative third-degree AVB?
This case demonstrates the feasibility of epicardial dual-chamber physiological pacing using an active-fixation electrode in a young child with postoperative AV block.
We report a 2-year-old small child with third-degree atrioventricular block (AVB) after ventricular septal defect (VSD) repair. Dual-chamber physiological pacing was successfully achieved via an epicardial approach using a Medtronic SelectSecure 3830 active-fixation electrode, targeting the left bundle branch area and high interatrial septum near the Bachmann bundle. The patient recovered uneventfully with stable pacing parameters. This is the first pediatric case of epicardial dual-chamber physiological pacing with this electrode, offering a feasible treatment for young children with postoperative third-degree AVB.

Tang et al. (2026) conducted a case report in Postoperative third-degree atrioventricular block after ventricular septal defect repair (n=1). Epicardial dual-chamber physiological pacing using Medtronic SelectSecure 3830 active-fixation electrode was evaluated on Recovery and pacing parameters. Epicardial dual-chamber physiological pacing using a Medtronic SelectSecure 3830 electrode was successfully achieved in a 2-year-old with postoperative third-degree AVB, with uneventful recovery.
