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. Discordant grading is defined either by an AVA <1 cm² while MPG is ≥40 mmHg/PVel <4 m/sec, or by an AVA ≥1 cm² and an MPG ≥40 mmHg/PVel ≥4 m/sec, the first … See more A precise evaluation of the severity of aortic valve stenosis (AS) is crucial for patient management and risk stratification, and to allocate symptoms legitimately to the valvular disease. … See more Fulfilling the precise and rigorous methodology presented above, the rate of patients with discordant grading is still between 20% and 30%, thus representing a common clinical … See more The important points discussed in the present paper can be summarised as follows: Discordant grading is common in clinical practice. The … See more The fact that discordant grading is common and that low flow is rare but impacts on prognosis is of no help in assessing whether these patients truly presented severe … See more dr audra horomanski
