Abstract [en]

Mitral valve leaflets have long been considered as passive flaps. The findings described in Chapter 29 suggest otherwise, but the possibility that the large stiffness of the anterior leaflet arises simply from leaflet residual strains that place passive leaflet elastic elements into the post-transitional nonlinear region of their stress-strain curves must be considered. In the nonlinear stress-strain curves obtained by May-Newman and Yin1 from excised mitral leaflets (Figure 29.1) this requires residual stretch of roughly 15% or more for the anterior leaflet.
