As shown, the severity of aortic stenosis can result from three criteria â valve area (size), aortic velocity and aortic valve gradient. Specific to size, a normal aortic valve area is >2 centimeters squared (cm2). If the valve area is between 1.5 and 2.0 cm2, the stenosis is mild; if the valve area is between 1.0 and 1.5 cm2, the stenosis is moderate; if the valve area is between 0.6 and 1.0 cm2, the stenosis is moderate-severe; areas of less than 0.6 cm2 constitute severe aortic stenosis. If you are curious, here is a picture of a normal aortic valve:
Usage notes [edit]. con-is a prefix added to many words to give a sense of with or together. The o is long before s and f, whence cÅnspÄ«rÅ and cÅnferÅ. Before b, p, and m, the n assimilates to m (whence com-). Other forms are co- , col- (used before l), and cor- (used before r).
