Abstract

Cardiomyopathies represent a well-known cause of heart failure and sudden death. Although cardiomyopathies are generally categorized in distinct nosographic entities, characterized by single gene-to-disease causal relationships, recently, oligogenic mutations have also been associated to relevant cardiac clinical features. We report the case of a master athlete carrying trigenic mutations in desmoglein-2 (DSG2), desmocollin-2 (DSC2) and heavy chain myosin 6 (MYH6), which determine a mild hypertrophic phenotype associated both to ventricular tachyarrhythmias and atrio-ventricular block. We discuss the differential diagnosis and prognostic approach in patient affected by complex cardiomyopathy phenotype, along with the importance of sport restriction and sudden death prevention.
