Overview
A normal aortic valve has three leafs (it is a tricuspid valve), but some patients are born with a congenital abnormality in which the aortic valve has two leaflets (a bicuspid aortic valve)[1].
Natural History
Typically, aortic stenosis due to calcification of a bicuspid valve appears earlier, at 40 to 50 years of age, whereas that due to calcification and degeneration of a tricuspid aortic valve appears later, at 70 to 80 years of age.
