The authors present 3 patients with asymmetric hypertrophic cardiomyopathy, which was diagnosed by echocardiography. Magnetic resonance imaging, however, proved superior in visualizing the cardiac anatomy of the left ventricle and enabled myocardial evaluation with determination of the location, severity, and extent of the abnormality. Magnetic resonance imaging can also differentiate unusual asymmetric hypertrophy from other pathologic states.
