title: [Athlete's heart and hypertrophic cardiomyopathy: contribution on clinical and morphologic differentiation].
abstract: Hypertrophic cardiomyopathy (HCM) is a complex genetic disorder usually diagnosed in a young adult population. The diagnosis is based on echocardiographic identification of left ventricular hypertrophy, associated with a non-dilated hyperdynamic chamber in the absence of another cardiac or systemic disorder. The differentiation between HCM and physiological left ventricular hypertrophy (athlete`s heart) is essential: HCM is the main cause of exercise-induced sudden cardiac death in the young and especially in young athletes with overlapping features in Athlete's Heart or HCM. Differentiation between physiological left ventricular hypertrophy and HCM is challenging. Echocardiography allows detailed assessment of left ventricular structure and function which is fundamental. Additional genetic studies for identification of the broad HCM phenotype can be necessary to differentiate between Athlete's Heart and HCM.
