A lead extraction procedure commenced to remove a right ventricular (rv) lead due to occlusion and non-function.A spectranetics lead locking device (lld) was inserted into the rv lead to provide traction.The physician began by using a spectranetics 14f glidelight laser sheath, encountering calcium in the device pocket and subclavian region.He then switched to a spectranetics 13f tightrail sub-c rotating dilator sheath, and was able to advance through the calcium at the clavicular ligament.He then switched back to the 14f glidelight device, but encountered stalled progression at the proximal end of the lead''s superior vena cava (svc) coil, so switched to a spectranetics 13f tightrail rotating dilator sheath.After approximately fifty clicks of the tightrail, the blades would no longer rotate.While the physician was providing traction with use of the lld, the tip of the rv lead dislodged and retracted back into the svc.A new tightrail was used, and the rv lead was pulled back, and was visible in the pocket.The physician cut away the calcium in the pocket, and was able to slide the tightrail distal of the occlusion.The rv lead was pulled through the tightrail and a 0.035 guide wire was placed through the tightrail to retain access for re-implantation.A new rv lead was placed and tested, and the numbers were good.They removed the original device and placed a new one.The patient became tachycardic and a large effusion was discovered.Rescue efforts began, including chest compressions and sternotomy.A hole the size of the tip of a pinky finger was discovered and repaired, and the patient survived the procedure.The surgeon believed the perforation could have been from the re-implantation, or could have been caused by traction forces provided by the lld when the rv lead was removed.This report captures the lld providing traction to the rv lead that could have caused or contributed to the rv perforation, requiring intervention.There was no alleged malfunction of the lld used in the procedure.
