Subcutaneous ICD implantation.

An 18-year-old patient, with hypertrophic cardiomyopathy and an implantable cardioverter defibrillator for 6 years, was admitted with inappropriate shocks as a consequence of a lead fracture (Sprint Quattro, Medtronic). The device was explanted and replaced with a new subcutaneous defibrillator (Cameron SQ-RX), without complications. This was the first time that a subcutaneous cardioverter defibrillator had been used in the Iberian Peninsula. The new implantable defibrillator, with subcutaneous lead and generator, can lower the risk of complications, including lead fracture or infection. Furthermore, this device has good rhythm diagnostic performance and therapeutic efficacy. Following the case report, we present a brief review of the new defibrillator with subcutaneous implantation.
