48 cases with subvalvular aortic stenosis, in which there were 46 cases with other congenital cardiac malformations. 主动脉瓣下狭窄(SAS)48例,46例合并其他先天性心脏病,仅2例为单纯主动脉瓣下狭窄(SAS)。

It is concluded that it is still valuable to diagnose supravalvular and valvular aortic stenosis by angiocardiography and cardiac catheterization that will be not required only for the diagnosis of simple subvalvular aortic stenosis. 说明先天性主动脉瓣上及瓣膜狭窄时心导管及心血管造影仍很有必要,单纯主动脉瓣下狭窄(SAS),可不必作心导管和心血管造影。
