Asymptomatic anterior perforation of an ICD lead into subcutaneous tissues.

A 71-year-old woman underwent routine impantable cardioverter defibrillator implantation. On a predischarge check the next day, electrical signals and thresholds were excellent and similar to those at implant. The chest X-ray was unremarkable and showed good lead position at the right ventricular apex (RVA). At a routine one-month postimplant visit, electrograms were found to be miniscule, and pacing could not be achieved. Chest X-ray and fluoroscopy suggested perforation, then this was confirmed by computed tomography scan. The tip of the lead was estimated to be within 7 mm of the surface of the skin. The system was removed surgically, and the patient continued to do well.
