Biventricular Arrhythmogenic Cardiomyopathy Mimicking Cardiac Sarcoidosis

Abstract

Noninvasive imaging is crucial for diagnosing and managing arrhythmogenic cardiomyopathy. Despite advanced multimodality imaging tools, challenges persist in differentiating it from other arrhythmogenic diseases (eg, cardiac sarcoidosis). We present a case of arrhythmogenic cardiomyopathy with an FLNC variant of uncertain significance exhibiting a phenocopy of cardiac sarcoidosis.
