Abstract:
0.05). The mechanical strength of dacron and thread were not significantly changed. Rb/Rc was approximately 1.2, H/Rc was approximately 1.4 and ?was approximately 10. These parameters accord with standard of prosthetic valve design. Conclusion The stented homograft valve can be cyropreserved by liquid nitrogen and accord with standard of prosthetic valve design.
