Notably, the boundary between inflammatory and genetic cardiomyopathy is blurred, as they can coexist: An early pathological series of arrhythmogenic right ventricular cardiomyopathy (ARVC) showed lymphocytic myocarditis in almost 2/3 of hearts,48 and a case series documented patients with acute chest pain, troponin elevations, and imaging typical of myocarditis who were found to have desmoplakin (DSP) cardiomyopathy. Here, DSP is linked to Arrhythmogenic right ventricular dysplasia.
