Abstract

Hypertrophic cardiomyopathy (HCM) is known for its heterogeneity, be it the inheritance pattern, morphological features, hemodynamics or the clinical presentation. Echocardiography plays a vital role in diagnosis and management of HCM. It may not be an exaggeration to state that echo has not only helped clinicians to precisely diagnose this condition but has actually made them to understand and evolve the etiopathogenesis, inheritance patterns, epidemiology, clinical presentation, hemodynamics and prognosis of the patients with this disease. This chapter covers the hypertrophy in HCM and abnormal coronary flow reserve predicts risk. The essential echo feature of HCM is hypertrophy of one or more segments of LV, measuring more than or equal to 15 mm at end diastole. Typically, the hypertrophy in HCM is asymmetric with frequent involvement of interventricular septum and anterior wall.
