WebThe Hakki equation underestimated AVA by 8% and showed larger errors for low flows. The relationship of transaortic pressure gradient vs. CO was moderately affected by afterload (12%) and, to a lesser extent, by LV compliance (1%) and preload (2%). WebHakki equation. AVA = Cardiac Output in L/min / √Peak to peak gradient in mmHg; Determining aortic valve area. The aortic valve (one of the two semilunar valves of the heart) is situated between the left ventricle and the aorta. It is basically the last structure in the heart the blood goes through before entering the systemic circulation.
