Subvalvular membranous aortic stenosis is usually accompanied by mild aortic insufficiency. This insufficiency is probably caused not by the valves but by the membrane. Resection of the membrane generally produces satisfactory results so far as the stenosis is concerned, and causes no significant aggravation of the insufficiency.
瓣下膜性主动脉狭窄通常伴有轻度主动脉瓣关闭不全。这种关闭不全可能不是由瓣膜引起的,而是由膜引起的。就狭窄而言,切除膜通常会产生令人满意的效果,并且不会导致关闭不全明显加重。
