Cardiac sarcoidosis concealed by arrhythmogenic right ventricular dysplasia/cardiomyopathy

A definitive diagnosis of cardiac sarcoidosis relies on the results of endomyocardial biopsy. In this Case Study Greif et al. describe a patient whose biopsy was negative for sarcoidosis—leading to a diagnosis of arrhythmogenic right ventricular dysplasia/cardiomyopathy. Sarcoidosis was only revealed after the patient had progressed to end-stage heart failure and undergone cardiac transplantation several years later.
