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 ... gradient is used in the Gorlin equation to calculate the AVA, not the peak gradient. The cardiac output is calculated using either the Fick principle ...

The mean transaortic valve pressure gradient is used in the Gorlin equation to calculate the aortic valve area, not the peak gradient. It is important to note that the Gorlin equation was ...

In patients greater than age 65, more than 90% of aortic stenosis involves trileaflet valves which have developed heavy calcification. [5] In these instances the calcium deposits are thought to ...
