Congenital Heart Defects (CHD) are problems with heart structures present at birth that affect the flow of blood through the heart. CHDs are the most common type of birth defect, affecting eight of every 1,000 newborns. There are approximately 35 different types of congenital heart defect. While many cases resolve themselves without medical intervention, most people with complex cases continue to need specialized heart treatment throughout their lives. Treatment for CHDs usually involves surgery, medicine and devices such as artificial valves and pacemakers. Organizations exist to provide information, support and resources to people facing Congenital Heart Defects in their lives.
