Key result
Echocardiography effectively detects supravalvular aortic stenosis noninvasively, but tends to underestimate the severity of the obstruction when compared to angiography.
Why the study?
Does echocardiography accurately detect and estimate the severity of supravalvular aortic stenosis compared to angiography?
Does echocardiography accurately detect and estimate the severity of supravalvular aortic stenosis compared to angiography?
Echocardiography is a valuable noninvasive tool for detecting supravalvular aortic stenosis, though it may underestimate obstruction severity compared to angiography.

Echocardiography may detect supravalvular aortic stenosis noninvasively yet underestimate severity; leaves open validation beyond single case reports.
A method for the echocardiographic detection of supravalvular aortic stenosis (SVAS) is described and the findings in a series of patients are presented. When compared to angiography, the echo tended to underestimate the severity of the supravalvular aortic obstruction. However, echocardiography appears to be a valuable, noninvasive method for detecting SVAS.
