title: Update on the use and outcomes of implantable cardioverter defibrillators in pediatric patients.
abstract: The vast majority of implantable cardioverter defibrillators (ICDs) continue to be implanted in the adult population. Accordingly, manufacturers develop devices and leads primarily for the adult population. Whilst the number of ICDs implanted in children is small in comparison, the potential benefits are large to this group. It is a common frustration among pediatric cardiologists whom implant devices that impressive technological developments continue to be developed for the adult population; as the population of children with ICDs is small, robust clinical studies often lag behind. By necessity, pediatric cardiologists and cardiothoracic surgeons have developed innovative techniques utilizing adult components in unusual configurations for children with complex congenital heart disease. As in the adult population, inappropriate shocks are one of the most limiting and concerning complications in the use of ICDs. Unfortunately, as will be discussed below, children are at increased risk of inappropriate shocks when compared with adults. The true impact of inappropriate shocks is increasingly being realized, and much of the focus in management of children with ICDs surrounds the prevention of inappropriate shocks.
