Abstract [en]

In this chapter (and the next) we analyze papillary mechanics for the F-series of experiments (See Appendix F), where papillary tip and base markers were placed inside the ventricle under direct visualization during cardiopulmonary bypass, allowing better measurement of papillary muscle lengths. In these hearts (F1-F11) the anterior papillary tip was assigned Marker #31, its base #32; the posterior papillary tip #33, its base #34. Muscle fibers are aligned along the long axes of papillary muscles, thus papillary muscle contractile force is exerted primarily along these axes. In this chapter, because the papillary muscle tips are connected via hinge chordae to the mitral annulus, we explore the orientation of these axes with respect to sites around the mitral annulus.
