Patent Ductus Arteriosus
It is important to recognise that PDA in the preterm infant and PDA in term babies and older children are two very distinct conditions with different implications and management - Dr Colin Tidy

Patent Ductus Arteriosus
Treatment is generally not considered, as the PDA usually closes on its own in the case of a premature baby.
Close monitoring is considered for full term babies, children and adults with small PDA and with no other health complications. During follow-up, if the baby does not have any other complications, it is considered to be closed. On the other hand, if the baby has certain heart problems or defects, the ductus arteriosus might be lifesaving.
In a premature baby, it may take one to two years. But in full term babies, PDA that remains open after several weeks rarely closes on its own. Medicines such as indomethacin or ibuprofen may be considered...

Closing a Patent Ductus Arteriosus: Sometimes Tincture of Time May Be the Best Approach
There have been many studies in our journal and others over the years regarding best ways to close a patent ductus arteriosus (PDA). But what if we just left the PDA alone to close by itself spontaneously?
Management of Patent Ductus Arteriosus in Premature Infants in 2020
The patent ductus arteriosus (PDA) is the most common cardiac condition affecting neonates (1). While there has been several studies and thousands of publications on the topic, the decision to treat the PDA is still strongly debated among cardiologists, surgeons, and neonatologists.
Management of the patent ductus arteriosus in preterm infants
Management of the patent ductus arteriosus (PDA) in preterm infants is one of the most contentious topics in neonatal intensive care. PDAs have been associated without proof of causation with numerous adverse outcomes,

Persistent Ductus Arteriosus in Critically Ill Preterm Infants
Persistent ductus arteriosus (PDA) is found with increased incidence in preterm infants, significantly affecting neonatal morbidity and mortality rates.
Patent Ductus Arteriosus
The ductus arteriosus is a small connection in the fetal heart helps oxygen rich blood to by-pass the immature baby’s lungs and flow into the body. This connection naturally closes shortly after birth. The connections that fail to close, are called patent ductus arteriosus, where the oxygen-rich and oxygen-poor combines together resulting in an increase in the workload of heart and various other complications.

In the fetus, the ductus arteriosus links the pulmonary artery with the aorta. At this time, the pressure in the pulmonary circulation is greater than in the systemic circulation to that blood flows from right to left i.e. from the pulmonary artery into the aorta.

StatPearls
The ductus arteriosus is a fetal vessel that allows the oxygenated blood from the placenta to bypass the fetal lungs in utero. At birth, a newborn inhales for the first time and the lungs fill with air, causing pulmonary vascular resistance to drop and blood to flow from the right ventricle to the lungs where it can undergo oxygenation. The increased arterial oxygen tension and decrease in blood flow through the ductus arteriosus causes the ductus to constrict and functionally close by 12 to 24 hours of age in healthy, full-term newborns, with permanent (anatomic) closure occurring within 2 to 3 weeks.
UK Healthcare
Patent ductus arteriosus (PDA) is a congenital heart defect that occurs when an artery called the ductus arteriosus stays open after birth instead of closing. In the womb, this artery routes blood away from the lungs. But when a baby starts breathing air after birth, the artery is no longer needed and typically closes within days. A PDA can cause the lung arteries to receive too much blood, which can tax the heart and lungs.
