If a fetus with congenital heart disease is detected in the 6th month of pregnancy, first of all, do not panic, but check the type and severity of congenital heart disease according to the cardiac ultrasound. If the congenital heart disease is simple, such as atrial defect, ventricular septal defect, or patent ductus arteriosus, it is perfectly possible to treat the child after birth, and some children can heal naturally without any surgical treatment. In the case of complex congenital heart disease, such as complete transposition of the great arteries, tetralogy of Fallot, and single ventricle, which are more complex heart diseases, the child will undergo several surgical procedures if born, and they may not be successful. Therefore, with complex congenital heart disease, you can discuss with your family to consider whether you need this child.
