Performance of phase contrast angiography in quantifying valvular regurgitation: an in-vitro model

, 1995
The proximal flowfield is the most promising region of interest in quantifying valvular regurgitation. The proximal isovelocity surface area (PISA) method has become the standard in attempting to quantify valvular regurgitation within this region ...

Diagnostic Value of Vena Contracta Area in the Quantification of Mitral Regurgitation Severity by Color Doppler 3D Echocardiography

, 2011
Background— Accurate quantification of mitral regurgitation (MR) is important for patient treatment and prognosis. Three-dimensional echocardiography allows for the direct measure of the regurgitant orifice area (ROA) by 3D ...

Assessment of tricuspid regurgitation secondary to mitral stenosis by proximal isovelocity surface area method

, 1998
We investigated the relationship between tricuspid planimetered regurgitant jet area obtained by transthoracic color flow mapping and the parameters derived using proximal isovelocity surface area (PISA) method (tricuspid regurgitant orifice area-RA ...
