Supravalvular aortic stenosis. Echocardiographic features.

Supravalvular aortic stenosis. Echocardiographic features.

The echocardiographic manifestations of segmental supravalvular aortic stenosis are described in 2 patients. The diagnosis was confirmed by cardiac catheterization in both and at operation in 1. A systematic echocardiographic approach to such patients is described. The characteristic finding in these patients was the narrowing of the diameter of the aortic lumen at the stenotic area just distal...

Echocardiographic features of supravalvular aortic stenosis.

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.

Echocardiographic detection of supravalvular aortic stenosis.

Supravalvular aortic stenosis.

The authors describe the case of an inborn supravalvular aortal stenosis in an adult patient who was successfully treated by a plastic operation of the stenotic portion of the ascendent aorta by means of a synthetic patch. At the same time also a plastic operation of an incompetent mitral valve was made.

Supravalvular Aortic Stenosis

In 3 patients obstruction to left ventricular outflow was shown to be due to a localized narrowing of the aortic root at the point of insertion of the aortic leaflets. The site of obstruction was localized by left heart catheterization and selective angiography. The pathologic findings in 2 patients are described and the problem of the surgical management of this unusual form of aortic stenosis...
