The prenatal diagnosis of various forms of left ventricular outflow tract obstruction has been reported in detail. However, the appearance and the characteristics of fetal aortic insufficiency have been described only in association with complete absence of the value. We report here a case of aortic insufficiency associated with severe aortic stenosis. Features characteristic of insufficiency were severe cardiomegaly due to left ventricle dilatation and the hypocontractility of the myocardium. The aortic root was enormously dilated and the semilunar valve showed thick and dysplastic cusps. On color Doppler, the retrograde high-velocity regurgitant jet was clearly visible.
各种形式的左心室流出道梗阻的产前诊断已有详细报道。然而,胎儿主动脉瓣关闭不全的表现和特征仅在瓣膜完全缺如的情况下被描述过。我们在此报告一例与严重主动脉瓣狭窄相关的主动脉瓣关闭不全病例。关闭不全的特征性表现为因左心室扩张导致的严重心脏肥大以及心肌收缩力减弱。主动脉根部显著扩张,半月瓣显示增厚且发育不良的瓣叶。在彩色多普勒检查中,逆行的高速反流束清晰可见。
