ARVC (arrhythmogenic right ventricular cardiomyopathy)
Cardiomyopathy in which right ventricular myocardium is progressively replaced by fibrofatty tissue, predisposing to right ventricular arrhythmia and sudden death. Leading cause of SCD in young athletes in Italy (Corrado series). Easily missed at autopsy unless the right ventricle is specifically examined.
