Introduction : Cardiac sarcoidosis (CS) is a granulomatous disorder affecting multiple organ systems including lungs, lymph nodes, a liver, skin, eyes, and gastrointestinal tract. The leading causes of death in patients with CS are cardiac arrhythmias, progressive heart failure, and progressive respiratory failure. Patients with CS are at high risk of sudden cardiac death from ventricular arrhythmias. Implantable cardioverter defibrillators (ICDs) have been used for primary and secondary prevention of sudden death in patients with CS. However, there are few reports about the clinical prognosis in CS patients with ICD. The purpose of this study was to identify the difference between prognosis of Japanese CS patients who received an ICD with and without other organ involvement.
