Cardiac sarcoidosis as initial presentation of multisystemic sarcoidosis

Abstract

Sarcoidosis is a multisystemic inflammatory disorder whose clinical presentation varies from asymptomatic disease to organ failure and death. Isolated cardiac sarcoidosis (CS) often escapes detection in absence of clinically apparent disease in other organs. Our case illustrates the evaluation of a young female presenting with syncopal attack with complete heart block which was later diagnosed being due to sarcoidosis. This is a rare case of sarcoidosis presenting with cardiac symptoms as its initial presentation. Our study emphasizes that the differential diagnosis of sarcoidosis should be kept in an advanced atrioventricular block especially in a young patient with no predisposing factors. Establishing the diagnosis of CS enables benefit from immunosuppressant therapy and prevents morbidity as well as mortality.
