Patent ductus arteriosus is treated by administering a drug, indomethacin, to close the duct. Surgery may be required if the duct does not close on its own as the baby develops.
The foramen ovale closes, becoming part of the interatrial septum. The Ductus arteriosus becomes the ligamentum arteriosum and the ductus venosus becomes the ligamentum venosum.

The main reason a doctor would want to keep the ductus arteriosus patent would be if the baby had some type of heart defect. An example of this would be transposition of the great vessels.
That is a very good question! In case of the fetus, the blood flow through the lungs is closed. So most of the blood passes through the foramen ovale to left atrium. Some blood goes to right ventricle. it is pumped by the right ventricle into pulmonary aorta. This blood passes to systemic aorta via ductus arteriosus. Both the blood flows stops after the birth of the baby. Baby takes a first breath. Blood starts to flow through the lungs. Due to pressure changes the foramen ovale get closed. By the same reason the ductus arteriosus get closed, as the circular muscles of the artery can contract.
The ductus arteriosus is a blood vessel connecting the pulmonary artery to the proximal descending aorta. Its function is to allow the blood from the right ventricle to bypass the fluid-filled non-functioning lungs of the developing fetus.
Patent ductus arteriosus is a condition in which the duct that channels blood between two main arteries does not close after the baby is born.
Also known as PDA. A condition in premature infants which causes abnormal fetal circulation
The medical conditions that may occur are respiratory distress syndrome, necrotizing enerocolitis, intraventricular hemorrhage, apnea of prematurity, patent ductus arteriosus, retinopathy of prematurity.

Ductus arteriosus
The function of the ductus arteriosus in unborn animals is to sent through the pulmonary artery to the aorta via the ductus arteriosus.
In fetal circulation, the ductus arteriosus is a connective vessel between the pulmonary artery and aorta. It works as to bypass the lungs, which are collapsed in the womb. After birth, the ductus arteriosus normally closes.
The foramen ovale closes, becoming part of the interatrial septum. The Ductus arteriosus becomes the ligamentum arteriosum and the ductus venosus becomes the ligamentum venosum.
Patent ductus arteriosus, or PDA, is a type of heart murmur that radiates to the back. It occurs when an infant's ductus arteriosus does not close after birth.
