With this condition, there is no opening, or a very small opening, from the left ventricle into the aorta. “Atresia” refers to a missing heart structure.
The valve cannot open properly, which means the blood can’t move from the left ventricle to the body. The only source of blood flow to the body will be through the ductus ateriosus.
Aortic atresia usually occurs in combination with other heart defects, typically hypoplastic left heart syndrome.
