WebQ9: What mean gradient value is considered very severe aortic stenosis? #ABIM #USMLE #NBME. 09 Apr 2024 17:22:32 WebFeb 23, 2024 · Some patients who appear to have severe AS (eg, AVA ≤1.0 cm 2) have a low transvalvular gradient (mean gradient <40 mmHg) across the aortic valve; these patients may have low gradient true severe AS or pseudo-severe AS. Diagnosis and evaluation of low gradient severe AS is discussed separately. Discordant grading is defined based upon the observation that one parameter suggests a moderate AS while the other suggests a severe AS.
