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.
