Correlation analysis of quantitative 2D and 3D colour doppler measures and mitral regurgitation severity. Spearman correlation (r) of (A) effective regurgitation orifice area (EROA) assessed through 3D vena contracta area (VCA), (B) 2D EROA using the proximal isovelocity surface are (PISA) method, (C) 2D regurgitation volume (RegVol) and (D) 3D RegVol with MR severity as graded by the two-dimensional reference method. All quantitative parameters were significantly (p < 0.05) associated with MR severity and 3D EROA showed highest correlation coefficient among all estimators.
