Bottom Line: Chest radiography revealed a significant split in the insulation of the lead allowing the inner wire to protrude.We considered the removal of the failed lead, but the removal of ICD lead is potentially a high risk procedure, so we cut and capped a proximal part of the failed lead and inserted a new lead.This is the first report of a St. Jude Riata® dual coil defibrillator lead failure with clinical and radiologic evidence of a defect in lead insulation in Korea.

ABSTRACT
A 50-year-old man, who underwent a procedure for an implantable cardioverter defibrillator (ICD), visited the outpatient department of our clinic after suffering multiple ICD shocks. The ICD interrogation revealed recurrent shock due to a high frequency of noise that is sensed by the device as ventricular fibrillation. Chest radiography revealed a significant split in the insulation of the lead allowing the inner wire to protrude. We considered the removal of the failed lead, but the removal of ICD lead is potentially a high risk procedure, so we cut and capped a proximal part of the failed lead and inserted a new lead. This is the first report of a St. Jude Riata® dual coil defibrillator lead failure with clinical and radiologic evidence of a defect in lead insulation in Korea.

Mentions: He was referred to our institute for catheter ablation of WPW syndrome. Contrary to expectations, ventricular fibrillation was reproducibly induced with programmed ventricular stimulation during an electrophysiologic study. Considering his episode of unexplained syncope, he underwent ICD implantation.3) A single dual coil ICD lead (St. Jude Medical, Inc., RIATA® 1570) was percutaneously introduced via the right subclavian vein because the left subclavian vein was not visible, then advanced and placed in RV apex. Intraoperative lead parameters including sensing amplitude, threshold, and lead impedance were all within appropriate limits. The ICD lead was connected to the ICD device (Atlas™+VR®, St. Jude Medical, Inc., St. Paul, MN, USA). They were placed in the right infraclavicular subcutaneous site. He had chest radiography after ICD implantation (Fig. 1).
