title: [Diagnosis and therapy of arrhythmogenic right ventricular cardiomyopathy].
abstract: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart muscle disease that predisposes to the occurrence of ventricular arrhythmias and sudden death, particularly in the young and athlete. The classic variant of the disease predominantly affects the right ventricle, but phenotypic variants with early and prevalent left ventricular involvement ("left-dominant" ARVC) have also been described, supporting the concept that arrhythmogenic cardiomyopathy is a disease of both ventricles. The diagnosis is multiparametric and is based on a series of criteria, including ECG abnormalities, arrhythmic manifestations, morpho-functional abnormalities and genetic defects. The main goal of therapy is sudden death prevention. Implant of a cardioverter-defibrillator is the most effective strategy for prevention of sudden death, but it should be reserved to selected patients after accurate risk stratification, in view of the high complication rate over a long-term follow-up, the costs and the significant psychological impact of such therapy, especially in the young individual. The other therapies (either pharmacological or not) are palliative and aimed at relieving symptoms and preventing disease progression. The definitive cure of ARVC will be based on the discovery of the molecular mechanisms that are involved in the etiology and pathogenesis of the disease.
