Pulmonary atresia
Alternative Names
Atresia - pulmonary; PA/IVS
Treatment
A medicine called prostaglandin E1 is usually used to help the blood move (circulate) into the lungs.
Other treatments include:
- Interventional heart catheterization to repair the problem.
- Open heart surgery to repair or replace the valve. This surgery can also be used to place a tube between the right ventricle and the pulmonary (lung) arteries.
- For some patients, the surgeon may reconstruct the heart as a single ventricle.
- Heart transplant
Outlook (Prognosis)
Most cases can be helped with surgery. However, how well a baby does depends on the quality of the blood vessels supplying the heart, how well the heart is beating, and the amount of leakiness of the other heart valves.
Some patients who have PA/IVS where the right ventricle is extremely small usually have several surgeris to help simulate normal circulation, but the surgeries do not exactly re-create normal circulation. A subgroup of these patients also have abnormal blood supply to the heart.
Possible Complications
- Delayed growth and development
- Seizures
- Heart attack
- Stroke
- Infectious endocarditis
- Heart failure
- Death
