(A to D) Areas of mature (i.e., older) scarring in left ventricular subendocardial areas. (E to G) Accumulation of mature adipocytes and fibrosis in the right ventricle. (H to J) Subepicardial and midmyocardial bands of fibrosis and adipose tissue in the lateral and posterolateral free walls of the left ventricle, a feature characteristic of disease in patients with desmosomal protein desmoplakin variants. (K, L) Recent (and ongoing) myocardial injury in the left ventricle.
