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).
The Spanish word con, pronounced much like the English word cone, not like con, is one of the most commonly used prepositions. In most uses, it is the equivalent of the English word with.. The word con is somewhat more versatile than the English with, and it may be used in places where with might not be used in English.
