WebFeb 6, 2024 · Severe AS is associated with V max ≥4.0 m/s, mean gradient ≥40 mm Hg, EOA ≤1.0 cm 2, EOA index ≤0.6 cm 2 /m 2, and Doppler index <0.25). However, up to 40% of patients with AS on echocardiography have discordant measures of AS severity, most commonly with small EOA but low V max and low Doppler-derived gradients. WebApr 10, 2024 · Transcatheter aortic valve implantation (TAVI) via femoral arterial access has become the treatment of choice for elderly patients with severe calcific aortic stenosis (AS) who are at intermediate or high risk for surgical aortic valve replacement (SAVR). 1,2 More recently, randomised trials have led to the approval of TAVI for patients at lower … WebSept. 24, 2024 The diagnosis of severe aortic stenosis is straightforward in the context of high transvalvular gradients associated with a severely reduced valve area (high-gradient aortic stenosis, or HGAS). The presence of discordant measurements with severely reduced valve area but low gradients, however, makes diagnosis much more challenging. crep light
