Fig. 9. Individual fiber and fiber bundle diameter quantification for porcine heart valves.

Fig. 9

While individual collagen fiber diameter for the four valve types showed comparable values (40–50 nm), the MT and TV (atrioventricular valves) had larger fiber bundle diameters than the AV and PV (outflow track valves). This result was also in agreement with the valve biaxial response and bending rigidity presented in Figs. 4–7, respectively.
