Ductus arteriosus: A short vessel through which blood headed from the heart via the pulmonary artery to the lungs is shunted before birth. This blood is shunted away from the lungs and returned to the aorta. When the shunt is open, it is said to be patent.
Patent ductus arteriosus (PDA) may also exist with other cardiac anomalies, which must be considered at the time of diagnosis. In many cases, the diagnosis and treatment of a patent ductus arteriosus (PDA) is critical for survival in neonates with severe obstructive lesions to either the right or left side of the heart.
