However, in recent years there is also not the same view proposed by some medical workers, which holds that children's language development retardation is related to the prenatal B-ultrasound diagnosis. For during the first trimester the fetus is more delicate and susceptible to the external physical and chemical factors, it is best not to perform much ultrasound examinations in the stage of early pregnancy. While during the late stage of pregnancy, it needs to use ultrasound examinations to ensure whether the fetus is normal, whether the amniotic fluid is too much, whether hydatidiform mole, whether fetal position is normal and so on. With the use of the ultrasound examination to pregnant women, the time tends to be quite short like only a few minutes, which normally has no impact on the fetus in the uterus in the late pregnancy stage.

While there is wide variety of fetal cardiovascular dysplasia with complex type, although as the the continuous progress of the ultrasound diagnostic instruments and the accumulated experience of personnel involved in this profession as well as the in-depth study, the fetal echocardiography rapidly develops, there are still many fetal heart abnormalities can not be pre – detection in the antenatal period, which is a fact. Maternal should obtain certain knowledge and understanding in this field. Thus the birth rate of children with congenital heart disease will be effectively controlled.
