In the womb, a baby's oxygen comes from the mother. Since there is no need for blood to pass through the lungs of the fetus, the blood is diverted away from the lungs, to the rest of the body, by an artery called the ductus arteriosus.
Once a baby is born and takes their first breath, the ductus arteriosus is no longer needed and begins to close. Under normal circumstances, the ductus arteriosus is completely closed in a few weeks.
With some babies, this process of closure either does not happen at all or does not happen completely, leaving a small opening. As a result, normal blood flow is affected. This condition is called patent ductus arteriosus (PDA)
Patent ductus arteriosus (PDA) is a persistent opening between the two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby's circulatory system before birth that usually closes shortly after birth. If it remains open, however, it's called a patent ductus arteriosus.
A small patent ductus arteriosus often doesn't cause problems and might never need treatment. However, a large patent ductus arteriosus left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure and other complications.
Treatment options for a patent ductus arteriosus include
