Summary : Hypertrophic cardiomyopathy is one of the most common cardiac genetic disorders. Cardiac magnetic resonance (CMR) has the advantage over echocardiography in that it shows lateral and apical regions of the myocardium and this is the major strength of the technique. Using CMR, hypertrophic cardiomyopathy is diagnosed using the same parameters as echocardiography namely: heterogeneous myocardial hypertrophy over 13 mm in male (excluding highly trained athlete) and 12 mm in female measured in end diastole. CMR after contrast injection may also show fibrosis as a hyper enhanced area within the LV myocardium.
