Late left ventricular perforation by active fixation pacemaker lead implanted in the right ventricular septum.

We report a rare case of late left ventricular perforation caused by a migrated pacemaker lead, which had been implanted in the right ventricular septum three months prior. Preoperative computed tomography findings revealed that the tip of the migrated pacemaker lead had perforated the ventricular wall near the intraventricular groove into the anterior chest wall.
