Complications

Without treatment, pulmonary atresia is nearly always fatal. Even after surgical repairs, you'll need to carefully monitor your child's health for any changes that could signal a problem.

People with structural heart problems, such as pulmonary atresia, are at a higher risk of infectious endocarditis than the general population. Infectious endocarditis is an inflammation of the valves and inner lining of the heart caused by a bacterial infection.

Even after treatment, people born with pulmonary atresia appear to face a higher risk of certain heart problems, such as abnormal heart rhythms (arrhythmias) and heart failure as adults.
