Cardiac implantable electronic devices in pediatric and congenital populations.

Pediatric patients and children and adults with congenital heart disease often will require implantation of cardiac implantable electronic devices (CIEDs) for management of a variety of cardiac rhythm pathologies. The safe and effective use of CIEDs in these patients requires an awareness of important differences between this special population and the adult populations for whom these devices were primarily developed and in whom they have been most thoroughly studied. These include issues of body size and growth, anticipated lifespan, anatomical issues related to implantation and the epidemiology of underlying rhythm issues. In this paper, we discuss these issues in the context of the current state of the art in pediatric and congenital heart disease patients with respect to implant and lead extraction strategies, physiological cardiac pacing and resynchronization, ICD indications and use of transvenous and subcutaneous devices, and the use of implantable monitoring devices.
