Antero-posterior diameter | Distance between the anterior and posterior point of mitral annulus. | cm |
Anterolateral-posteromedial diameter | Longest distance between two points on the annulus that are derived by intersecting the annulus and a line perpendicular to antero-posterior diameter. | cm |
Commissural diameter | Distance between two points on the annulus. Both points are derived by intersecting the annulus spline with a plane that goes through both end points of the coaptation and is perpendicular to the best fitting plane. | cm |
Annulus circumference (3D) | Real length of annulus spline | cm |
Annulus area (3D) | Size of core area | cm2 |
Annulus area (2D) | Size of area derived by projecting the annulus spline onto the Best Fitting Plane. | cm2 |
Non-planar Angle | Angle between the plane formed by anterior point of MA and commissural diameter and the plane formed by posterior point of MA and commissural diameter. | ° |
