Clinically it is measured using the proximal isovelocity surface area pisa method, by pisa, the eroa in this patient was calculated at 0. Such patients usually have severe mr substantiated by other echocardiographic findings and clinical decision making is straightforward. Obtain a cfd of the mr jet with a good pisa formation under zoomed view, The eroa may be underestimated when there is multiple secondary regurgitant jets or overestimated when there is a late systolic primary jet of mr. Additionally, an anglecorrected pisa method was proposed as the standard approach seem to underestimate especially ventricular tr. Org › article › myapproachtopisamy approach to pisa eroa in mitral regurgitation a critical, The pisa method estimates mitral regurgitation severity by assuming hemispheric flow convergence proximal to the regurgitant orifice. Regurgitant flow rate is derived from aliasing velocity, and dividing by peak mr velocity yields the effective regurgitant orifice area eroa.
