Aortic stenosis is a narrowing of the aortic valve or a narrowing of the aorta directly above (supravalvar) or below (subaortic) the aortic valve. Normally, oxygen-rich blood is pumped from the left ventricle, through the aortic valve, into the aorta and then out to the body. With aortic stenosis, it makes it very hard for the heart to pump blood to the body. Depending on the severity of the stenosis, open heart surgery may be needed to correct the defect. Another option may be a balloon valvuloplasty.
Subaortic stenosis refers to a narrowing of the left ventricle just below the aortic valve, which blood passes through to go into the aorta. This stenosis limits the flow of blood out of the left ventricle. This condition may be congenital or may be due to a particular form of cardiomyopathy known as "idiopathic hypertrophic subaortic stenosis" (IHSS).
Supravalvular aortic stenosis (SVAS) is a congenital narrowing of the ascending aorta which can occur as a congenital defect itself or as one component of Williams syndrome.
Congenital aortic stenosis occurs in 3 to 6 percent of all children with congenital heart defects. Relatively few children are symptomatic in infancy, but the incidence of problems increases sharply in adulthood. Congenital aortic stenosis occurs four times more often in boys than in girls.
