Sarcoidosis of the Heart

Myocardial involvement in sarcoidosis occurs in about 27% of patients. Clinical manifestations include ventricular arrhythmias, conduction abnormalities, and sudden death. Diagnosis requires clinical suspicion and may be supported by electrocardiography, echocardiography, thallium imaging, gallium‐67 scanning, and myocardial biopsy. Steroids seem to be beneficial in the treatment of myocardial sarcoidosis. Those who do not respond to medical treatment may benefit from cardiac transplantation.
