Narrowing of the Aorta
The aorta is the large artery that exits the left side of the heart to take red oxygenated blood to the rest of the body. As it ascends from the heart it arches over the airway to travel down in the back of the left chest to the lower parts of the body. As the aorta arches it may become narrowed, an abnormality called aortic coarctation.
Patent Ductus Arteriosus
The ductus arteriosus is a large artery connecting the lung artery with the aorta. It is required during development of the heart and lungs to allow blood to bypass the lungs during foetal life when they are collapsed and do not contain air. The ductus arteriosus has a muscular type of wall that causes it normally to close in the first few days of life.
