When the left side of the heart in an infant (hypo plastic left heart) not developed, what is the valve or tube called and located that is supposed to close when the infant is born?
From the American Heart Association: In hypoplastic left heart syndrome, the left side of the heart — including the aorta, aortic valve, left ventricle and mitral valve — is underdeveloped. Blood returning from the lungs must flow through an opening in the wall between the atria (atrial septal defect). The right ventricle pumps the blood into the pulmonary artery and blood reaches the aorta through a patent ductus arteriosus. (The ductus arteriosus short-circuits blood from right to left in a fetus, where there is no point in pushing the blood through the lungs.
