Delayed cardiac perforation by one small body diameter defibrillator lead

We report a 37-year-old man who presented with continuous chest pain 6 weeks after implantable cardioverter-defibrillator implantation. Implantable cardioverter-defibrillator interrogation indicated complete loss of capture even with maximum output. Chest radiography and echocardiography confirmed extracardiac location of lead tip. After lead repositioning in electrophysiology laboratory, acceptable pacing threshold was obtained with no complication. This report demonstrates a case of delayed cardiac perforation after implantation of the St Jude Medical Durata implantable cardioverter-defibrillator lead.     

Cardiac perforation due to a fracture of a recalled Accufix bipolar active fixation pacing lead 29 years after implantation: A case report

The Accufix bipolar active fixation atrial pacing lead (Model 330-801; Telectronics) can have mechanical complications due to a fracture of its J retention wire. An 80-year-old man had the Accufix atrial pacing lead implanted 29 years prior, and surgical removal was required because a part of the lead was perforating the apex of the right ventricle. Regular follow-up examinations are recommended to eliminate the possibility of protrusion and detachment of the J retention wire, even if the clinical course after implantation is stable for a prolonged period.
