45 patients with supravalvular aortic stenosis (SVAS) were investigated by cross-sectional echocardiography from a total number of 164 patients observed in Göttingen. In 44 cases the diagnosis of SVAS could be confirmed by this noninvasive method. There was a good correlation between the ratio of the echo-circular surface (aortic anulus and the point of maximal obstruction) and the ratio of the angio-circular surface, as well as the ratio of the echo-circular surface and the measured pressure gradient. Cross-sectional echocardiography is therefore a valuable noninvasive method for evaluating SVAS and for estimating the severity of obstruction.
