Whether it is possible to have a child with congenital heart disease is mainly determined by the severity of the disease. If the condition is mild, pregnancy can be normal; if the condition is severe, pregnancy is not recommended in most cases. 1. Mild conditions: For example, mild atrial septal defects and arterial ductus arteriosus do not cause obvious blood circulation abnormalities, so pregnancy can be normal if all the physical indicators are in good condition. 2. More serious conditions: more serious ventricular septal defects, tetralogy of Fallot and transposition of the great arteries and other diseases, will seriously affect the blood circulation, some people will cause hypoxia and cyanosis, the corresponding patients are not recommended for pregnancy. The discovery of congenital heart disease should be timely medical care, observation to confirm the diagnosis of specific conditions, and standardized treatment under the guidance of clinicians to avoid delays in the condition.
