Conference paper


Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a myocardial disease in which the myocardium of the right ventricular free wall is partially or almost entirely replaced by fatty or fibrofatty tissue [1–3]. The process begins at the epicardium and gradually extends through the myocardium towards the subendocardium. The anterior right ventricular outflow tract, ]the apex, and the inferoposterior wall are the most frequently affected sites, constituting the so-called “triangle of dysplasia” [4]. Histological examination of affected myocardial tissue demonstrates residual myocytes interspersed among adipocytes and fibrous tissue, providing a substrate for ventricular arrhythmias that may range from asymptomatic premature ventricular beats to ventricular tachycardia, which is typically of left bundle branch block morphology, merging into ventricular fibrillation. Sudden cardiac death may be the first manifestation of the disease, particularly during effort [2]. The left ventricle may be involved with disease progression accounting for heart failure [3–5].
