Arrhythmogenic right ventricular cardiomyopathy
ARVC is a genetic disorder. Diagnosis relies on consensus criteria: Key features include epsilon waves, T-wave inversion, right ventricular-origin ventricular tachycardia (VT), and imaging evidence of right ventricular aneurysms or fatty infiltration.Cardiovascular magnetic resonance (CMR) is the most valuable diagnostic tool: It detects right ventricular wall thinning, dyskinesia, fatty infiltration, and late gadolinium enhancement (indicating fibrosis) in both right and left ventricles. ARVC is frequently biventricular: Histopathologically, left ventricular involvement occurs in ~76% of cases
