PDA: The PDA is an artery that connects the pulmonary artery to the aorta. It is present in everyone and is necessary for survival during fetal life. It allows blood to bypass the fluid filled lungs of the fetus and flow into the aorta and through the umbilical arteries back to the placenta. It normally closes within the first 72-96 hours of life. Occasionally it fails to close, requiring intervention.

When do you worry about a patent ductus arteriosus?

Seldom: In a child whose ductus has not closed, the decision to try to induce closure with medication, or to ligate, is made by the physicians. An older child's patent ductus missed in infancy may be picked up as a murmur; it is not subtle, and usually needs treatment to prevent damage to the lungs and to enable junior to keep up in sports.

To clarify -- there's almost never a need to "worry" this will be a long-term threat to health. There's much that can't be put into 400 words, and I agree with my colleague's suggestion that this be fixed by school age at the latest

Causes the PDA: The PDA is a critical vessel that allows the blood to bypass the lungs and get to the placenta while babys are still inside, in mom's uterus. The lungs are full of amniotic fluid and don't do any gas exchange (o2 delivery and co2 release)
eveyone is born with a pda, it persists... Open (patent) most commonly in premature babies.
There is no absolute answer as to why it stays open in some people.

What are the symptoms of patent ductus arteriosus?
1 doctor answer • 7 doctors weighed in
Dr. Marco Paliottaanswered

Several symptoms. : A (p)persistent (d)ductus (a) allows blood to be shunted from the aorta to the pulmonary artery therefore causing more blood to go to the lungs. If the PDA is large, the increased blood flow to the lungs will determine a faster rate and work of breathing, the heart will enlarge and failure to thrive (grow appropriately). A PDA can and should be closed by a cardiologist or surgeon.

Should be closed depending on the size of the ductus.

Ductus Arteriosus: A ductus arteriosus is a vessel that allows babies to survive while in utero... It allows blood to bypass the lungs which are full of amniotic fluid and get to the placenta where gas exchange occurs.
A patent ductus arteriosus is simply a vessel that has not closed (patent) once born the lungs relax and the pressures fall. As such, extra blood goes to the lungs, inefficient work for the heart.
