In recent years, cardiogenetics is emerging as a major discipline for the study of many pathologies, with immediate clinical effects for patients who were previously managed by the cardiologist alone. Recent acquisitions have allowed significant improvements in terms of diagnostic characterization, prognostic stratification and guidance for treatment for both patients with genetic disease and their family members. At present, cardiogenetics has an important role for the clinical management of patients with cardiomyopathies and channelopathies. We present an updated review of the literature and a proposal of organizational model.
