A lead extraction procedure commenced to remove a right atrial (ra) and a right ventricular (rv) lead due to cied system/pocket infection, with plans to implant an abbott vascular aveir leadless pacemaker system.The implantation was completed and tested successfully.Due to the patient''s age and fragile state, it was decided to not insert a transesophageal echocardiography (tee) probe for the lead extraction portion of the procedure.Spectranetics lead locking devices (llds) were inserted into each lead to provide traction.Using a spectranetics 14f glidelight laser sheath on the rv lead, advancement was made into the right atrium when the rv lead came free.As the rv lead was being removed through the glidelight, it became entangled with the ra lead, causing the ra lead tip to dislodge from the right atrial appendage.Once the rv lead was completely removed, efforts focused on full removal of the ra lead.Using the 14f glidelight, smooth advancement was made to the superior vena cava (svc) region, and then, using traction, the physician began to pull the lead from the heart.The lead became stuck in the subclavian region, but with additional lasing, the ra lead came free.The leadless pacemaker was again tested successfully, and the pocket was closed.As the patient was just outside the or, being transferred into recovery, her blood pressure dropped dramatically.She was transferred back to the or, a tee probe was placed, and a pericardial effusion was detected in the right atrium (suspected ra perforation).A pericardiocentesis was successfully performed with no additional intervention required.The patient was stabilized and survived the procedure.This report captures the lld providing traction to the ra lead when the suspected perforation occurred, requiring intervention.There was no alleged malfunction of any spectranetics devices in use during the procedure.
