It was reported that the left ventricular (lv) lead exhibited a high pacing threshold and an extraction was planned.While using a laser to extract the lead, the physician had to pull hard in order for the lead to loosen and the lv lead became dislodged to be removed.It was noted when the physician was pulling, the lead pulled apart in such a way that the insulation came out of the lead itself and the distal portion containing the bipolar electrodes could not get out of the venous anatomy before the lead fractured.The two distal electrodes of the lead broke off from the remainder of the lead and still remain in the lateral vein of the patients heart, seeing as there was no means to retrieve it.At the time, it was difficult to tell if there was any conductor or insulation left connecting the two electrodes, as on fluoroscopy it looked like there was nothing between the electrodes and "they are just floating in place." the rest of the lv lead was removed and the lv lead was replaced.No patient complications have been reported as a result of this event.
