fanveu Background the twodimensional proximal isovelocity surface area 2d pisa method in the quantification of an effective regurgitation orifice area eroa has limitations in functional mitral valve regurgitation fmr, particularly in noncircular coaptation defects. Pisa proximal isovelocity surface area is a phenomenon that occurs when liquid flows through a circular orifice. A consistent significant underestimation of eroa and regurgitant volume using 2d pisa was observed. The pisa method for quantification of mitral regurgitation. A an example of the shape of the doppler pisa shell which does not resemble a true hemispheric pisa but is ‘urchinoid’ in shape due to the direction of flow black arrows, b. farr and beyond support services
