effective regurgitant orifice area(English)

• determined with the PISA method by lowering the Nyquist aliasing velocity to identify the hemispheric shell, measuring the radius from orifice to first aliasing, and applying the standard formula on the basis of the ratio between flow rate (aliasing velocity x radius) and peak orifice velocity (regurgitant jet velocity by continuous-wave Doppler)
