Abstract：
Parachute mitral valve (PMV) is a common form of congenital mitral stenosis and is difficult to diagnose prenatally. This report describes a fetal case of PMV with coarctation of the aorta that was diagnosed at 25 weeks\' gestation by echocardiography and confirmed at autopsy. We describe the ultrasonographic features in this case and present a useful sign for making a prenatal diagnosis of PMV.
摘要：
降落伞二尖瓣（PMV）是先天性二尖瓣狭窄的常见形式，难以在产前诊断。本报告描述了一例胎儿PMV伴主动脉缩窄的病例，该病例在妊娠25周时通过超声心动图诊断并在尸检中得到证实。我们描述了这种情况下的超声特征，并为PMV的产前诊断提供了有用的标志。
