title: Morphologic features of cardiac sarcoidosis in native hearts of patients having cardiac transplantation.
abstract: Described herein are 10 patients who underwent cardiac transplantation (CT) for severe chronic systolic heart failure resulting from cardiac sarcoidosis. None had the diagnosis of sarcoidosis established before CT except for the 3 patients who earlier had had a portion of left ventricular wall excised for insertion of a left ventricular assist device and non-caseating granulomas were present in the removed myocardium. Although none of the 10 patients had significant narrowing of any of the epicardial coronary arteries, all had focal scarring of the walls of the left and right ventricles and ventricular septum and all had dilated ventricular cavities. The patients with the most ventricular wall scarring tended to have the fewest sarcoid granulomas in the ventricular walls. Two patients had no sarcoid granulomas in the excised heart although one did have typical sarcoid granulomas in the portion of left ventricular wall excised to insert a left ventricular assist device. Patients with cardiac sarcoidosis severe enough to warrant CT had characteristic cardiac ventricular morphologic findings, and no dysfunction of other non-cardiac organs, making clinical diagnosis of cardiac sarcoidosis rather difficult.
