Abstract:

Objective To explore the safety and feasibility of implanting leadless pacemakers via the internal jugular vein in children with congenital heart disease (CHD) of small age and low weight who have developed third-degree atrioventricular block (AVB) after surgery. Methods A retrospective analysis was conducted on the clinical data of a child with grade three AVB after congenital heart disease surgery, as well as the implantation of leadless pacemaker through the internal jugular vein. Results A 6.5-year-old girl (weighing 15 kg) with syncope secondary to third-degree AVB following congenital heart defect repair underwent successful implantation of an AVEIR leadless cardiac pacemaker via the internal jugular vein after comprehensive evaluation of vascular diameter and cardiac dimensions. Postoperative pacing parameters were good, clinical symptoms were eliminated, and no pacemaker-related complications occurred. Conclusions In low-weight young children, after thorough preoperative vascular and cardiac function evaluations, the intracervical vein approach for leadless cardiac pacemaker implantation proves a safe and feasible choice.
