(rollover to compare with supravalvular)
||What Are Its Effects?
The left ventricle, the main pumping chamber of the heart, pumps oxygen-rich blood through the aortic valve into the aorta, which carries it to the body tissues. If the opening to the aorta is obstructed, as in Aortic Stenosis, the left ventricle must work harder to move blood in this way.
In severe cases, this may cause the left ventricle to increase in size (hypertrophy), which may lead to irregular heartbeat (arrhythmia) and sudden death.
In Subvalvular Aortic Stenosis, insufficiency (leaking) of the aortic valve may occur.
