title: [Clinico-roentgenological diagnosis of aortic subvalvular stenosis].
abstract: On the basis of analysis of data on 36 patients with idiopathic hypertrophic subaortic stenosis, 2 groups of patients were distinguished. In patients of group 1 the outlines of the cardiac shadow resembled those of the aortic type, but there was a bulging in the cranial part of the left ventricle due to its hypertrophy, particularly manifest in the prestenotic part of its outflow tract. In patients of group 2 the shape of the cardiac shadow was characterized by the straightening out of the left outline, i.e. by the absence of signs caused by a sharp hypertrophy of the left ventricular myocardium.
