Aortic valve stenosis is usually defined by restricted systolic opening of the valve leaflets, with a mean transvalvular pressure gradient of at least 10 mm Hg. The cause of the stenosis can be further defined based on the anatomy and disease process affecting the valve.
The complete Gorlin formula for aortic stenosis is: Valve area (cm2) = Cardiac Output (ml/min) Heart Rate (beats/min) * Systolic Ejection Period (s) * 44.3 * square root(mean gradient) However, the Hakki modification of the Gorlin formula allows for a rough and ready assessment of aortic valve area during a procedure. It is based on the observation that at most heart rates the product of HR x SEP x 44.3 is close to 1000.
