What does PDA mean in pregnancy?
Patent ductus arteriosus (PDA) is a persistent opening between the two major blood vessels leading from the heart. The opening (ductus arteriosus) is a normal part of a baby’s circulatory system in the womb that usually closes shortly after birth. If it remains open, it’s called a patent ductus arteriosus.
What does PDA mean in surgery?
Patent ductus arteriosus (PDA) surgery is done to close a blood vessel called the ductus arteriosus. Normally, this blood vessel closes after birth. But in PDA, it stays open. This causes some of the blood that should go from the heart to the body to go to the lungs instead.
Where is PDA located?
The patent ductus arteriosus (PDA) is a vascular structure that connects the proximal descending aorta to the roof of the main pulmonary artery near the origin of the left branch pulmonary artery. This essential fetal structure normally closes spontaneously after birth.

When is PDA diagnosed?
The murmur, along with symptoms of heart failure in a premature infant, most often lead to the diagnosis of patent ductus arteriosus. A chest X-ray will show an enlarged heart and evidence of a large amount of blood flow to the lungs. An echocardiogram is done to confirm the diagnosis.
How is PDA treated in newborns?
In a premature baby, nonsteroidal anti-inflammatory drugs (NSAIDs) — such as ibuprofen (Infants’ Advil, Infants’ Motrin, others), available over the counter, or indomethacin (Indocin), available by prescription — might be used to help close a PDA .
