Implantable cardioverter defibrillators (ICDs) provide a safe and effective treatment for life-threatening ventricular arrhythmias. Several investigators have demonstrated that ICD use in pediatric patients is feasible, effective, and associated with a low risk of sudden death in follow-up.1 However, ICD placement in young children can usually be accomplished only by a thoracotomy approach involving multiple incisions and placement of epicardial defibrillation electrodes. We describe a less invasive yet efficacious lead configuration likely to be associated with a lower complication rate.
Clinical summary
A 3.5-year-old, 17.5-kg, previously healthy boy came to the emergency department of a referring hospital in status epilepticus. He was found to be in ventricular fibrillation, which responded to external defibrillation. He was resuscitated and treated with a lidocaine infusion and phenytoin. He made a full neurologic recovery and was transferred to our institution for further management. There was no family history of cardiac disease. His physical examination, electrocardiography, echocardiography, and cardiac magnetic resonance imaging results were normal. A decision was made to implant an ICD for this episode of aborted sudden death. Because of his age, size, and probable lifelong need for defibrillation, the decision was made to place a single subcutaneous defibrillation lead and "active can" configuration.
In the operating room, with the patient under general anesthesia, the apex of the heart was exposed through a subxiphoid incision. A Medtronic 7841 epicardial
