Pacemaker lead perforation causing hemopericardium eight years after implantation.

The number of patients with intracardiac devices, including permanent pacemakers and implantable cardioverter-defibrillators is increasing. Lead perforation is a recognized complication which most often occurs during or shortly following pacemaker implantation. Late lead perforation occurring over 30 days after device insertion is a rare, potentially life-threatening complication. We present a case of late lead perforation unmasked greater than eight years after pacemaker implantation by initiation of anticoagulation.
