3D EROA improves diagnostic value in patient with severe mitral regurgitation (MR). Receiver operating characteristic (ROC) analysis displaying sensitivity and false positives (1-specificity) to discriminate patients with moderate or severe MR according to the reference method. AUC indicates area under the curve. (A) ROC curve shows that 3D effective regurgitation orifice area (EROA) is the most accurate parameter for the detection of severe MR. Further, AUC of (B) 2D EROA, (C) 3D regurgitation volume (RegVol) and (D) 2D RegVol was slightly lower.
