Letter to the Editor: Contemporary Screening and Treatment of Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy (HCM) is an autosomal dominant genetic heart disorder.1 HCM is characterized by left ventricular (LV) hypertrophy (LVH) without LV dilatation, particularly of the interventricular septum, in the absence of other predisposing conditions such as hypertension or valvular disease. Most affected individuals remain unidentified and asymptomatic.2 HCM is a relatively common genetic disease, with a 1 in 500 prevalence by echocardiogram in the general population.
