Fig. 3

3D plots comparing the impact of increasing AoR on LAV calculated using LAD P-A or LAD. A The 3D graph shows that LAD P-A is diminished when AoR diameter increases. B The 3D graph shows that the wide range of AoR has no influence on the linear correlation between LAV and LAD. The color code is linked to the “severity” of the atrial enlargement, then red indicates those cases that are “at risk”. In graph A, there are less “severe” cases, but this is obviously an artifact, or in other words a technical error
