Subpectoral implantable cardioverter defibrillator implantation in a 20 kg-weighted child

An 11-year-old boy (weight 20 kg, height 124 cm), who was survived from ventricular fibrillation due to hypertrophic cardiomyopathy, admitted to our institution for implantable cardioveter defibrillator (ICD) implantation. We implanted a transvenous single coil lead and a device (Medtronic model 6943, GEM II VR 7229 Cx) in the subpectoral pocket. We selected this system because of less restriction on normal cardiac function, low operative morbidity, and expectation of long-term defibrillation threshold stability. Subpectoral implantation is cosmetically acceptable comparing with abdominal area. Lead insertion by cut-down technique is feasible and recommended to avoid lead-related complications. ICDs are infrequently used in pediatric patients and prospective study with long-term follow-up will be required to ascertain the prognosis for young survivors from sudden cardiac death.
