Aortic stenosis (AS) is defined as severe in the presence of: mean gradient ≥40 mmHg, peak aortic velocity ≥4 m/s, and aortic valve area (AVA) ≤1 cm 2 (or an indexed AVA ≤0.6 cm 2 /m 2).However, up to 40% of patients have a discrepancy between gradient and AVA, i.e. AVA ≤1 cm 2 (indicating severe AS) and a moderate … WebWhat is a normal Lvot? measurement of LVOT diameter. normal range is between 1.6 and 2.4 cm. What is considered a significant Lvoto? A gradient greater than or equal to 50 mm Hg is generally recognized as the threshold at which LVOT obstruction becomes hemodynamically significant.
