In these situations, the child will have a bluish color, or cyanosis, of the skin or lips. At other times, blood can go to the lungs that should go to the body. This puts a strain on the heart and lungs. If a part of the heart does not develop completely, the heart may not function well when the child is born. These situations are very serious and may require several surgical procedures.
Most defects cause a whispering sound, or murmur, as blood moves through the heart.
To make an accurate diagnosis of a congenital defect, a doctor may want to order tests such as an ultrasound or cardiac catheterization. Many persons with congenital heart defects can live normal lives. Some may need to limit their activities and take medicines. Almost all persons with congenital defects will need to take antibiotics before dental procedures or certain surgeries. This is to prevent bacteria from infecting their heart.
