Quantitative colour doppler measurements correlate with clinical parameters in patients with mitral regurgitation. (A) Correlation matrix of important quantitative 2D and 3D colour doppler echocardiography estimators in patients with MR. Spearman´s ρ is coloured accordingly and significant (p < 0.05) coefficients are labelled (* p < 0.05, **p < 0.01, ***p < 0.001). Correlation analysis in patients with mitral regurgitation to evaluate (B) the association of 2D PISA and 3D VCA for estimation of effective regurgitation orifice area (EROA) (r = 0.332, p = 0.019). Correlation analysis of 3D VCA with (C) 3D regurgitant volume (RegVol) (r = 0.929, p < 0.0001) and (D) 2D RegVol (r = 0.281, p = 0.048), accordingly.
