RF = RVol / total stroke volume through the regurgitant valve × 100; the method (and therefore the denominator) must be chosen.

Method (defines the denominator)Concomitant lesion

Regurgitant volume (RVol)

Denominator: total SV through the regurgitant valve (SV)

AR RVol (MR volumetric RF with coexisting AR) (RVol)

Enter method to calculate.

Choose the method: the regurgitant fraction is undefined until its denominator is stated.
