ABSTRACT

An 18-years-old adolescent with asymmetric mid-ventricular hypertrophic cardiomyopathy, undiagnosed because he did not present symptoms. The electrocardiogram indicated an increase in the QT interval, without arrhythmias; the transthoracic echocardiogram revealed asymmetric mid-ventricular hypertrophy, with mild obstruction of the left ventricular outflow tract; the mitral valve was thickened and calcified. Symptoms were not found because the outflow tract obstruction was not noticeable; as hypertrophy increased, the symptoms appeared. The thickening and calcification of the mitral valve, uncommon for the patient's age, could cause mitral regurgitation or heart failure.
