WebOct 20, 2024 · The indexed AVA, used as an inclusion criterion, has some limitations, especially in patients with a high body mass index, which may lead to an overestimation of AS severity. Conclusions This study based on a registry of patients with LG SAS and preserved LV ejection fraction managed in routine practice shows that DI is a reliable … 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 … 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 problem.
