Abstract:Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a primary myocardial disorder that is characterized by localized or diffuse atrophy of predominantly right ventricular myocardium with subsequent replacement by fatty and fibrous tissue. Arrhythmias of right ventricular origin are the main clinical manifestation. Affected patients present with ventricular premature beats and nonsustained or sustained ventricular tachycardia demonstrating a left bundle branch block pattern. However, since ventricular tachycardia may also degenerate into ventricular fibrillation, sudden death may be the first manifestation of ARVC. In recent years, ARVC has been more and more recognized as an important and frequent cause of ventricular tachyarrhythmias and sudden cardiac death, particularly in young patients and athletes, with apparently normal hearts. Evidence of the disease is found in 30–50% of family members. ARVC is a genetically heterogeneous disease. The diagnosis is based on electrocardiographic abnormalities and the identification of regional or global right ventricular dysfunction and fibrolipomatosis. Although several potentially causative genes have been identified, currently, genetic testing is not part of the routine diagnostic work-up. An implantable cardioverter-defibrillator is indicated in selected high-risk patients with ARVC (i. e., patients with life-threatening ventricular tachycardia or survivors of sudden cardiac death). The clinical course of the disease is often characterized by progression. In individual patients heart transplantation may become necessary.
