Aortic hypoplasia

Decreased growth of the aorta, the blood vessel that delivers oxygen-rich blood from the left ventricle to the body.  It can involve congenital (or birth defect) coarctation (i.e., a discrete narrowing or constriction the distal segment of the aorta).  Found in individuals with Williams syndrome, it is a consequence of supravalvular aortic stenosis, which involves the elastin gene.
