Here is an example calculation to assess the severity of mitral regurgitation using the proximal isovelocity surface area pisa method. By the continuity equation, eroa is calculated as flow divided by peak velocity at the exact time when radius was measured, or qv max severe tr ≥ 0. The pisa method estimates mitral regurgitation severity by assuming hemispheric flow convergence proximal to the regurgitant orifice. Previous correction formulae were more empirically based by example on hemielliptic 9 or hemiellipsoidal 10 geometric models. The me 3cv, me 4cv, me 2cv, or me avlax are good views.

Pisa equation for evaluation of mr severity eroa 2πr². Regurgitant flow rate is derived from aliasing velocity, and dividing by peak mr velocity yields the effective regurgitant orifice area eroa, 57 cm 2, consistent with severe mr, Background effective regurgitant orifice area eroa in mitral regurgitation mr is difficult to quantify, 65, and other independent predictors of severe mr grade by cardiac mri in their data set included left ventricular enddiastolic volume and the presence of a flail leaflet.

Mr grading is done primarily by using three color doppler methods distal jet area, vena contracta, and the use of the proximal isovelocity surface area pisa or flow convergence method to calculate effective regurgitant orifice area eroa and regurgitant mr volume.

Current recommendations favour the use of quantitative parameters for the assessment of mitral regurgitation mr severity and the effective regurgitant orifice area eroa derived from the proximal isovelocity surface area pisa method has been demonstrated as a predictor of outcome. The geometric assumptions behind the calculation of tricuspid effective regurgitant orifice area eroa by pisa, namely a hemispheric flow convergence proximal to a circular orifice subtended by a flat surface, are not met in patients with vstr, and thus pisa may result in systematic underestimation of tr severity.
