The Subcutaneous Implantable Cardioverter-Defibrillator as Part of Dual Device Therapy in Complex Congenital Heart Disease

Abstract

We report the case of a 44-year-old with unrepaired complex congenital heart disease (CHD), a pre-existing permanent pacemaker, and a subcutaneous implantable cardioverter-defibrillator (SICD) implanted for secondary prevention. Right parasternal electrode positioning and step-down defibrillation testing were integrated. Application of the SICD for device therapy in CHD patients remains quite limited but can have an expanding role in this population.
