It was reported that there was a cardiac perforation by the left ventricular (lv) lead which resulted in an increased capture threshold, a loss of capture, and an increased pacing lead impedance (pli).The patient¿s hemodynamic state deteriorated due to the perforation.The lead was explanted to resolve the event and the patient was stable following the procedure.

Additional information: as received, a complaint lead was returned in one piece.Visual examination found the four filers of the inner coil were fractured which is consistent with suture tie down forces, and there were no other anomalies noted.X-ray analysis was performed, which did not find any other anomalies.The reported events of increased capture threshold, a loss of capture, and increased impedance were confirmed and isolated the damage from suture tie down forces.
