Usefulness of Delayed Enhancement Magnetic Resonance Imaging to Differentiate Dilated Phase of Hypertrophic Cardiomyopathy and Dilated Cardiomyopathy

The HCM patients had more DE than the DCM patients, and DE volume correlated to lower global and local LV function. DE-MRI may be useful to evaluate myocardial damage in HCM patients, and to differentiate the dilated phase of HCM from DCM.
