Abstract
An analysis is given of the clinical features of 27 instances of pure aortic stenosis occurring in subjects under the age of 50. Of these 27 cases, 26 did not give a history of rheumatic fever; 20 were male. Only 8 gave symptoms of cardiac disease. The blood pressure was normal in all. 12 had normal ecgs. 3 showed left ventricular preponderance. X-ray showed moderate cardiac enlargement in 2, slight enlargement in 12 and no enlargement in 1. The ascending aorta was prominent in 14 of 15 cases that had roentgenograms, and calcification of the aortic valve was seen in 8 of these 15 patients. On the basis of these findings, it is stated that this lesion cannot be differentiated from subaortic stenosis except possibly by angiocardiography. It is doubtful that the lesion is of rheumatic origin.
