Supravalvular stenotic mitral ring. A new case with surgical correction

In this report, we present a case of supravalvular stenotic mitral ring in
a child. The lesion created a picture of severe mitral stenosis and was
successfully managed by resection of the ring. No other malformations of
the mitral apparatus or left ventricular outlfow tract were found. On
analyzing the diagnostic criteria, we concluded that there appears to be
only one useful criterion--the angiographic morphology. However, when ther-
is an associated ventricular septal defect or findings of Shone's complex,
we should suspect supravalvular ring rather than any other form of mitral
stenosis.
