regurgitant fraction

Regurgitant fraction is the percentage of blood that regurgitates back through the aortic valve to the left ventricle due to aortic insufficiency, or through the mitral valve to the atrium due to mitral insufficiency. It is measured as the amount of blood regurgitated into a cardiac chamber divided by the stroke volume.
