Prognosis
The outcome varies for every child. If the condition is left uncorrected it may be fatal, but the prognosis has greatly improved over the years for babies with pulmonary atresia. Some factors that affect how well the child does include how well the heart is beating, the condition of the blood vessels that supply the heart, and how leaky the other heart valves are. Most cases of pulmonary atresia can be helped with surgery. If the patient's right ventricle is exceptionally small, many surgeries will be needed in order to help stimulate normal circulation of blood to the heart.
If uncorrected, babies with this type of congenital heart disease may only survive for the first few days of life while the fetal shunts between left and right circulations remain patent. However, there are cases of uncorrected Pulmonary Atresia in which the baby has survived.
Many children with pulmonary atresia will go on to lead 'normal' lives. Patients are usually seen regularly throughout their lifetime by a cardiologist to be sure that their heart is functioning properly. They have an increased risk of endocarditis.
