NT testing is not unfamiliar to many mothers, but for many pregnant expectant mothers, testing for NT at the twelfth week of pregnancy can be confusing. So, can NT detect congenital heart disease in fetuses?
NT examination is an ultrasound examination that can screen for diseases in the fetus in the abdomen. Congenital heart disease, also known as congenital heart disease, has a very high incidence rate among newborns in China and is also the "number one killer" of infant and toddler deaths in China.
In fact, the vast majority of congenital heart disease can be detected through NT screening during fetal development. NT refers to the thickness of the transparent layer of the fetal neck during early pregnancy, and thickening of NT may be associated with abnormalities in fetal chromosomes, cardiovascular system, and other aspects.
Clinical medical experts have found that fetuses with normal chromosomes have a significantly higher probability of developing congenital heart disease if their NT thickness increases. From this, it can be seen that NT thickening is a high-risk factor for congenital heart disease.
Moreover, when fetal cardiac abnormalities are detected through ultrasound, further detailed examination should be conducted. Of course, the above methods cannot be the ultimate basis for determining fetal congenital heart disease. If the fetal chromosomes are normal, further monitoring and examination of the fetal heart are needed. During the 11-13 weeks of pregnancy, fetal congenital heart disease can be detected through NT, which is beneficial for the diagnosis and treatment of congenital heart disease in children.
