Patent Ductus Arteriosus Specialist in Wichita, KS

Patent Ductus Arteriosus (PDA) is an opening between the aortic and pulmonary arteries. The pulmonary artery goes from the heart to the lungs and the aortic artery goes from the heart to the smaller arteries throughout the body. A PDA is often noted in the first few weeks or months after birth. A PDA is a normal part of blood circulation while baby is developing in the uterus. It is used to allow oxygen-rich blood to bypass the lungs. However, if it remains open after birth, it allows oxygen-rich blood from the aorta to mix with oxygen-poor blood from the pulmonary artery.
