Triangle of dysplasia in ARVD

Triangle of dysplasia in arrhythmogenic right ventricular dysplasia (ARVD)

Pathological features of arrhythmogenic right ventricular dysplasia (ARVD – also known as arrhythmogenic right ventricular cardiomyopathy – ARVC), namely the replacement of right ventricular wall myocardium by fat and fibrous tissue and aneurysms are seen at right ventricular apex, posterior free wall and outflow tract. These regions together constitute the triangle of dysplasia.
