Patent Ductus ArteriosusPatent ductus arteriosus (PDA) is a heart problem that occurs soon after birth in some babies. In PDA, abnormal blood flow occurs between two of the major arteries connected to the heart.
Before birth, the two major arteries-the aorta and the pulmonary (PULL-mun-ary) artery-are connected by a blood vessel called the ductus arteriosus. This vessel is an essential part of fetal blood circulation.
Within minutes or up to a few days after birth, the vessel is supposed to close as part of the normal changes occurring in the baby's circulation.
In some babies, however, the ductus arteriosus remains open (patent). This opening allows oxygen-rich blood from the aorta to mix with oxygen-poor blood from the pulmonary artery. This can put strain on the heart and increase blood pressure in the lung arteries.
Patent 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 conus arteriosus is a single, wide arterial vessel leaving the ventricle and passing ventrally over the right atrium.
Ductus arteriosus
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.
The function of the ductus arteriosus in unborn animals is to sent through the pulmonary artery to the aorta via the ductus arteriosus.

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.
The ductus arteriosus allows blood to pass around the lungs while the baby is in utero. After birth, it closes off so the lungs can oxygenate the blood.
