Insulation failure and externalized conductor of a single-coil Kentrox lead: an ongoing story?

Conductor externalization is a frequent complication with the St. Jude Medical Riata lead. Single case reports also reported externalization of conductors for dual-coil Biotronik leads. Up to now, conductor externalization has not yet been reported for any single coil leads. We report for the first time an externalization of conductors in a Biotronik Kentrox single-coil implantable cardioverter defibrillator (ICD) lead.
