Current implantable cardioverter-defibrillator (ICD) guidelines do not impose age limitations for ICD implantation (IMPL) and generator exchange (GE); however, patients (pts) should be expected to survive 1 year. With higher age, comorbidity mortality due non-sudden cardiac death increase. Thus, the benefit of therapy in elderly pts remains unclear. Mortality after IMPL or GE ≥ 75 years was assessed.
