Chapter 24 Posterior Leaflet Open

• We begin by examining the maximum extent of posterior leaflet opening relative to the mitral annulus. To view this, in each sample frame we performed a translation to place Marker #22 at the origin, perform 2 rotations to place Marker #18 on the x-axis, then performed a final rotation to place anterior commissure Marker #16 into the x-y plane. This placed the mitral annulus into the x-y plane (to very close approximation) at each sample time. We then view the resulting mitral valve geometry along the z-axis, looking from the left atrium toward the left ventricle. Appendix E provides frame-by-frame animations showing the geometry of the mitral valve as described by three-dimensional cubic splines passing through connected marker locations during a representative beat (from maximum LVP in one beat to maximum LVP in the following beat) for the hearts studied in this fashion.
