Hypertrophic cardiomyopathy(HCM)is the most common inherited heart disease and is associated with adverse cardiovascular events including sudden cardiac death and heart failure.Therefore,accurate diagnosis and risk stratification are of great importance in the clinical management of HCM.Cardiac magnetic resonance imaging can assess the cardiac structure,function and tissue characteristics,playing a crucial role in differential diagnosis and prognosis evaluation in HCM.New magnetic resonance imaging techniques,including feature tracking,diffusion tensor imaging and 4D flow,hold great promise in the investigation of the development mechanisms and early diagnosis of HCM.
