Patent Ductus Arteriosus

• Ductus Arteriosus is a fetal vessel that allows the oxygenated blood from the placenta to bypass the lungs in utero
• Ductus arteriosus is a blood vessel that connects the pulmonary artery and the aorta during fetal development.
• After birth, the lungs expand with air, leading to increased oxygen levels in the blood. This change, along with increased systemic vascular resistance, usually causes the ductus arteriosus to constrict and eventually close within the first few days of life.
• Patent Ductus Arteriosus is a congenital heart disease involving the point of intersection of pulmonary artery and aorta
