The Doppler recordings provide an accurate assessment of peak and mean gradients. The aortic valve area can be calculated and measured by planimetry. Detection of sclerodegenerative changes of the ...

Aortic stenosis is described as mild ... The difference between these two pressures is the pressure gradient. The mean transaortic valve pressure gradient is used in the Gorlin equation to ...

The most important hemodynamic parameters for staging are the maximum transaortic velocity (V max), the mean pressure gradient (ΔP) across the aortic valve, and the aortic valve area (AVA).

Navitor Vision enhances visibility and precision in TAVI procedures, offering a less invasive alternative to surgical aortic ...

It is recommended that patients with mild aortic stenosis (i.e., AVA ≥1.5 cm 2; mean gradient ≤25 mm Hg with normal flow) may undergo repeat echocardiography after 9-12 months, while moderate ...
