Aveir retrievable, 38-mm length, leadless pacemaker implantation in a 23-kg pediatric patient with congenital heart disease.

Abstract

Complications are more prevalent in pediatric patients receiving pacemaker implants. We performed a retrospective review of a retrievable, 38 mm leadless pacemaker implantation in a 23-kg pediatric patient. An active 9-year-old, 23 kg male patient with tetralogy of Fallot with intermittent pacing need presented with a fractured lead and pacing need. He underwent implant of a retrievable leadless pacemaker (Abbott Aveir) via internal jugular vein access, without complication, and with echocardiographic guidance. His threshold was stable at 1.25 V @0.4 ms, with stable impedance and sensing at 5-month follow-up. Aveir retrievable leadless pacemakers can be implanted safely in a child with tetralogy of Fallot, as small as 23 kilograms.
