Imaging Methods in the Diagnosis of Hypertrophic Cardiomyopathy

The review concerns to the methods of cardiac imaging in the diagnosis, treatment and risk stratification of sudden cardiac death in patients with hypertrophic cardiomyopathy (HCMP). Keyword searches in e-Library, PubMed, Scopus, and Web of Science databases for the period from 2014 to 2023 were used for the period from 2014 to 2023 for sources in Russian and English. The review presents the possibilities of echocardiographic examination in assessing the presence, distribution and severity of myocardial hypertrophy, the condition of the mitral valve and subvalvular structures, obstruction of the left ventricular outflow tract, systolic and diastolic functions. The role of computed tomography, which has the capabilities for more accurate assessment of myocardial thickness, coronary artery anatomy with identification of the "myocardial bridging" is discussed. Magnetic resonance imaging (MRI) in the diagnosis and management of patients with HCMP is presented in detail. Using MRI, it is possible to identify various pathologic phenotypes by obtaining high-quality images with a sharp contrast between the myocardium and the blood pool. Among the advantages of the MRI, it should point the obtaining of detailed tissue characteristics of the myocardium which makes it possible to visualize area of fibrosis. The significance of other imaging methods, in particular single-photon emission tomography, myocardial scintigraphy and coronary angiography, in the management of patients with HCMP is noted.
