According to Johns Hopkins, Aortic stenosis means that your baby has a heart valve that is too narrow or is blocked. The aortic valve is 1 of 4 heart valves that keep blood flowing through the heart. The valves make sure blood flows in only one direction. The aortic valve keeps blood flowing from the left ventricle to the aorta. Your child may be born with aortic stenosis (congenital). Or it may develop later (acquired). It occurs more often in boys than in girls.
A normal aortic valve has 3 flaps (leaflets) that act as a one-way door. In aortic stenosis, the valve doesn’t work as it should or has an abnormal number of leaflets that don’t work correctly. That makes it harder for the leaflets to open and let blood flow from the left ventricle to the aorta.
Aortic stenosis may be mild, moderate, or severe. It depends on how much of the blood is blocked. The condition may get worse over time. It may also occur with other heart problems or conditions.
