Parameters of the mitral valve analysis. Anterior view of the mitral valve in mid-systole (3D TEE, surface rendering images). The semi-automated analysis of the mitral valve gives the following results: Panel a: scheme of the mitral valve including the mid-anterior point (blue dot), the mid-posterior point (red dot), the anterior-posterior diameter as distance between mid-anterior and mid-posterior point (purple line), and the circumference framing the annulus area (yellow circle line). Panel b: the anterolateral-posteromedial diameter gives the maximal distance in the horizontal plane (red line), and the intercommissural diameter gives the horizontal diameter at the commissures’ insertion (blue line). Panel c: the anterior (blue) and posterior (green) leaflet area is defined as the area between the annulus and the coaptation line (red line) not including the part of the leaflets that form the coaptation zone
