Bland–Altman plot for evaluation of agreement between the findings of VCA direct planimetry (DP) and MPR-derived VCA in the diagnosis of MR severity. VCA: vena contracta area; MPR: multiplanar reconstruction; MR: mitral regurgitation. Mean difference: −0.3. Upper limit of agreement [−0.3 + (1.96 × 0.1667)]. Lower limit of agreement [−0.3-(1.96 × 0.1667)]
