Insulation Damage in a Shock Wire: An Unexpected Fluoroscopic Image

We report on a patient with a single‐chamber implantable cardioverter defibrillator admitted with an increase in high‐voltage lead impedance, detected with home‐monitoring, and inappropriate shocks due to noise on the electrogram. Chest x‐ray revealed no abnormalities. Fluoroscopy before the revision procedure showed insulation failure with migration of the shock wire in the heart. The lead was removed and replaced with a new shock lead. This is, as far as we know, the first report on such a particular insulation failure, detected with home‐monitoring and inappropriate shocks.
