After several children with precordial disease in a row, the operation went very well. But the mood was not happy. Because the mothers of these patients are all over 35 years old, and one of the children is congenitally stupid. With the liberalization of the second child, the number of elderly mothers will surely increase gradually. To avoid the birth of children with complicated precocious heart disease, mothers-to-be should always come to a major hospital for a 4D ultrasound examination at around 25 weeks of pregnancy to understand the development of the fetus’ heart and consider inducing labor if it is a child with complicated precocious heart disease. Children with precocious heart disease are often combined with other malformations, and amniotic fluid screening may be considered to confirm chromosomal disorders.
