Finding out that your baby has a heart condition during pregnancy requires a case-by-case decision about whether to keep the fetus. There are many types of fetal congenital heart disease, some of which are treatable. If a fetus is found to have heart disease such as atrial septal defect, ventricular septal defect, or arterial ductus arteriosus during pregnancy, most babies can lead a normal life and learn through surgery and other treatments as early as possible after the birth of the fetus. These types of fetuses are recommended to be retained during pregnancy. Fetuses found to have severe heart disease during pregnancy, such as tetralogy of Fallot, fetal single ventricle, or a combination of multiple heart malformations. At this time, some of the fetuses may have intrauterine fetal death, some of the fetuses may cause severe asphyxia or even death after birth, or the effect of surgical treatment after birth is poor, at this time, the fetus may not be retained, and the pregnancy should be terminated promptly during pregnancy. If you find your baby has heart disease during pregnancy, you should consult a regular hospital in time and make a decision on whether to keep the fetus under the guidance of a professional doctor, and should not give up the fetus blindly.
