How long you can live with congenital heart disease depends mainly on the type, severity and treatment of congenital heart disease. There are many types of congenital heart disease, which can be divided into simple congenital heart disease and complex congenital heart disease. Simple congenital heart disease, such as a simple atrial septal defect or patent ductus arteriosus, has the potential to heal spontaneously after birth. Even if it does not heal spontaneously, there are many treatment options, such as interventional blocking or open-heart surgery. After successful surgery, the patient’s anatomical abnormalities are improved and life expectancy is not affected. However, in the case of complex congenital heart disease, such as cyanotic congenital heart disease like Tetralogy of Fallot, the condition of the child is more severe and the prognosis is worse. In severe cases, the fetus may die from the disease while still in the mother’s body. If the child is not given active treatment after birth, the child will become more and more severe until death. Of course, there are also relatively simple and complex congenital heart diseases, which may be able to live into adulthood, but in general the life expectancy is shorter than normal. Therefore, the question of how long congenital heart disease can live cannot be generalized, but depends on the severity of the disease and treatment, some cases will not affect the life expectancy, and some will seriously affect it.
