The anatomy of the fetal heart can be well seen by real-time cross sectional ultrasonography between 16 weeks' gestation and term. Many major structural abnormalities can be excluded in early pregnancy even if only one section of the fetal heart is studied. We have accurately predicted structural cardiac malformation in nine cases in the mid-trimester of pregnancy. Five pregnancies were interrupted for extracardiac abnormalities. In two cases of severe cardiac abnormality termination of pregnancy was chosen by the parents. In the remaining pregnancies where an abnormality was predicted delivery took place in a centre equipped for immediate care of an affected infant. This gave the infant the optimum chance of survival.
在妊娠16周与足月之间，通过实时横断面超声检查能够清晰地观察到胎儿心脏的解剖结构。即便仅研究胎儿心脏的一个切面，在孕早期也可排除许多主要的结构异常。我们已准确预测出妊娠中期9例胎儿心脏结构畸形。5例因心外异常而终止妊娠。在2例严重心脏异常的病例中，父母选择了终止妊娠。在其余预测有异常的妊娠中，分娩在配备有救治患病婴儿的即时护理设施的中心进行。这为婴儿提供了最佳的生存机会。
