WebDec 29, 2013 · For the calculation of the aortic valve surface, the continuity equation can be applied. Continuity equation: A1.v1 = A2.v2. Where: A=area (∏r 2) cm 2. v=velocity, cm/s (can be used as maximum speed or TVI) so: Aortic valve area (AVA)= ( D LVOT/2 ) 2 x 3:14 x Vmax LVOT/Vmax peak in AoS jet. Where: D LVOT=diameter LVOT in cm. WebHowever, as we see in Figure 2.34, these two conditions by themselves do not guarantee continuity at a point. The function in this figure satisfies both of our first two conditions, but is still not continuous at a. We must add a third condition to our list: iii. lim x → a f ( x) = f ( a).
