How do you calculate the aortic regurgitant volume?

Aortic regurgitant volume and %RF were calculated using the following equations: aortic regurgitant volume = [aortic outflow volume] − [mitral inflow volume]; %RF = [aortic regurgitant volume]/[aortic outflow volume] × 100.

What is aortic valve area index?

Background: To account for differences in body size in patients with aortic stenosis, aortic valve area (AVA) is divided by body surface area (BSA) to calculate indexed AVA (AVAindex). Cut-off values for severe stenosis are <1.0 cm2 for AVA and <0.6 cm2/m2 for AVAindex.
