Abstract
A case of muscular subaortic stenosis has been reported. This case was first considered to be a ventricular septal defect because of the history and a hursh systolic murmur heard over the entire precordium with cardiac enlargement. However, the routine angiocardiogram and brachial pressure curve demonstrated a characteristic pattern of muscular subaortic stenosis. As to the frequent appearance of ECG with short P-R interval, we have suggested that anomalous conduction which may be caused by complicated rheumatic lesion rather than hypertrophied septal muscle.
