What is the cause of congenital heart disease?

First, there is a family history of congenital heart disease. It is not uncommon that siblings suffer from CHD at the same time, and parents and children suffer from CHD at the same time, and the nature of the disease is very similar. If the mother's first child has congenital heart disease, the risk of the second child is about 2%.

Secondly, let's talk about the causes of virus infection. In the first three months of pregnancy, especially in the third to eighth weeks of pregnancy, if a woman is infected by the virus, then the fetus is prone to cardiovascular malformations. Rubella virus is the main cause of fetal congenital heart disease.

Finally, bad habits are also important reasons. Smoking by husband and passive smoking by wife can cause congenital heart disease in children. Incidence rate of congenital heart disease in infants is two times higher than that of non smoking mothers. If a husband and wife get pregnant in the same room after drinking, the fetal chromosome will be abnormal. Most of the babies with alcoholism are accompanied by cardiovascular abnormalities.
