3-D marker coordinates of mitral annular saddlehorn (#17) and mid-lateral markers (#19), as well as anterior and posterior mitral leaflet markers plotted onto the xy-plane at mid-systole (left column) and at maximum opening (right column) with the saddlehorn marker as the origin of a right-handed cartesian coordinate system (see methods for details). Data are mean values from all animals (A: COS (n=12), B: RSAR (n=12), C: PHYSIO (n=12), D: ETL (n=10), E: GEO (n=12)).
