Joint Committee on Aviation Pathology: XIII. Sarcoid and the heart--an aeromedical risk.

Sarcoid lesions of the heart are reported in 13% to 20% of sarcoidosis patients. Sudden death and ventricular arrhythmias occur in 40% to 50%. In view of this frequency and life-threatening significance, review of military aircrew with documented sarcoidosis for myocardial involvement was undertaken.
