Cardiac sarcoidosis Benedict T Costello,1,2 James Nadel,3 Andrew J Taylor,1,2 1Department of Cardiovascular Medicine, The Alfred Hospital, 2Baker IDI Heart and Diabetes Research Institute, Melbourne, VIC, 3School of Medicine, University of Notre Dame, Sydney, NSW, Australia Abstract: Cardiac sarcoidosis is a rare but life-threatening condition, requiring a high degree of clinical suspicion and low threshold for investigation to make the diagnosis. The cardiac manifestations include heart failure, conducting system disease, and arrhythmias predisposing to sudden cardiac death. A number of investigations are available to assist in making the diagnosis. The diagnosis may be made from the clinical history and evidence of inflammation on imaging modalities in the active phase and evidence of myocardial scarring in the chronic phase.
