How long does a person with congenital heart disease survive?
It depends on the severity of the congenital heart defect. Mild forms like a small ventricular septal defect has a near normal life span while a severe one like hypoplastic left heart syndrome has very limited life span without surgical treatment. But most severe defects are now treatable with either surgical or device therapy so that long term outlook is much better than what it was a few decades ago. Atrial septal defect, ventricular septal defect and patent ductus arteriosus can be closed using devices without opening the chest. Narrowing of valves like pulmonary stenosis or aortic stenosis can be treated by balloon dilatation.
