Figure 1: Mitral Annular Parameters.

Figure 1:

The mitral valve annulus (non-planar larger ring) and aortic valve annulus (smaller planar ring) are shown. Blue and red spheres indicate anterior and posterior points on the mitral annulus, respectively. The red curve conveys the coaptation line of the anterior and posterior leaflets. key measured variables are indicated in yellow.

A. Annular Circumference; B. Anterior-Posterior Diameter; C. Anterolateral-Posteromedial Diameter; D. Commissural Diameter; E. Annular Height; F. Annulus Non-planar angle.
