A case of asymmetric hypertrophic cardiomyopathy with mild subaortic stenosis and partial systolic anterior motion of the mitral valve. Since the pressure gradient obtained by phase contrast imaging was rather low, echocardiographic reevaluation and/or follow-up was recommended. The case also demonstrates a typical pattern of myocardial fibrosis in the basal and midventricular septal segments at the anterior and posterior right ventricular insertion points.
