Calculation of eroa by pisa method.

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.
