Shock-induced right ventricular pacing failure caused by a short circuit: Uncommon but life-threatening complication of the Riata lead
نویسندگان
چکیده
Introduction The Riata and Riata ST implantable cardioverter-defibrillator (ICD) leads, a narrow caliber silicone lead without an outer jacket, have been shown to be prone to structural and electrical failure. While much interest has been shown in potentially lethal high-voltage (HV) failures caused by electrical short circuits due to a breach in the ethylene tetrafluoroethylene (ETFE) insulation of the defibrillation cables, the clinical manifestation of Riata/ST lead failures has not been fully elucidated. In this report, we present a case of shock-induced Riata lead pacing failure and discuss clinical approach to the management of Riata/ST leads.

QuickSite (St Jude Medical, Sylmar, CA, USA) is a silicone and polyurethane-insulated coronary sinus pacing lead. Riata lead (St Jude Medical, Sylmar, CA, USA) is a silicone insulated right ventricular shock lead. Recently, insulation breach of silicone based leads raised a huge concern. Fluoroscopic examination of these two leads in the same patient revealed externalization of these two leads....

A 76-year-old man presented after a series of six shocks in quick succession from his implanted biventricular defibrillator, without relief of palpitations and pre-syncope. Initial 12-lead electrocardiogram revealed ventricular tachycardia at 180 b.p.m. One 200 J external shock was delivered with successful return to sinus rhythm. Interrogation of the device revealed that the device had been re...

We describe the case of a patient who presented with multiple implantable cardioverter-defibrillator (ICD) shock discharges 12 months after device implantation. Upon device interrogation, intermittent oversensing of electrical noise and potential ICD lead failure were suggested by a significant increase in the sensing integrity counter (SIC), a cumulative count of very short ventricular sensed ...
