Results of human left atrial cast volume measurements by 3DE and 2DE. a) 3DE and 2DE volumes in comparison to true volumes of casts. b-d) Bland-Altman paired difference plots of volumetric measurements in comparison to true volumes. Black lines represent limits of agreement (mean ± 1.96 SD) and blue lines bias. 2DE volume – volume calculated by 2D echocardiographic biplane area-length method, 3DE GE and 3DE TomTec – 3D echocardiographic volume measured by GE 4D LVQ and TomTec 4D LV-Function softwares, respectively, r – Pearson correlation coefficient.
