A review of 18 cases with discrete subaortic stenosis (DSS) revealed that involvement of the aortic valve cusps in the basic process was present in 16. In these 16 cases, extensions of fibroelastic tissue from the site of the DSS toward the base or superior to the base of one or more cusps were seen. In seven of the involved cases, deformity of a cusp was associated with these extensions. Valvular aortic insufficiency in cases with DSS might be caused by extensions of the fibroelastic tissue to the aortic cusps.
对18例离散性主动脉瓣下狭窄（DSS）病例的回顾显示，16例基本病变累及主动脉瓣叶。在这16例病例中，可见纤维弹性组织从DSS部位向一个或多个瓣叶基部或基部上方延伸。在7例受累病例中，瓣叶畸形与这些延伸有关。DSS病例中的主动脉瓣关闭不全可能是由于纤维弹性组织向主动脉瓣叶延伸所致。
