Overview
A normal aortic valve has three leafs (it is a tricuspid valve), but some valves have 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.
