Sarcoidosis with cardiac involvement

Patients with significant cardiac sarcoidosis are at increased risk of sudden death from ventricular dysrhythmias or conduction disturbances. We report a patient in whom there was radiographic and histologic evidence of systemic sarcoidosis; though histologic confirmation of involvement of heart by sarcoidosis is lacking, the clinical manifestations, radionuclide image findings, rhythm disturbances, and the response to steroid therapy are strong evidence in favor of myocardial involvement by the granulomatous process.
