Correlation of the Echocardiographic Parameters and the MR Classification
Spearman’s correlation test indicated that MVVTI/LVOTVTI, MVAVTI-i, MVAVTI/LVOTDVTI, and E velocity-LA area-i were highly and significantly correlated with MR severity classification with correlation coefficients of 0.776, 0.672, 0.822, and 0.698, respectively (all p-values <0.001) (Table 2).
