Hypertrophic cardiomyopathy (HCM) is a genetic cardiac disease. Its early detection is important because it is the most common cause of sudden cardiac death among young people. However, HCM is often a dilemma for clinicians because it manifests with diverse phenotypic expressions and clinical courses. With the advances in imaging tech¬nology, magnetic resonance (MR) imaging and multidetector com¬puted tomography (CT) serve as suitable modalities for detecting and characterizing HCM and obtaining information for appropriate man¬agement of cases of HCM, although echocardiography is currently the most widely used modality. This article is an overview of the definition of HCM, its various phenotypes, risk stratification of HCM, and the potential application of cardiac MR imaging and multidetector CT for the assessment of HCM.
