| Outline of Final Research Achievements |
Purpose of this research is to evaluate the leaflet and bulging sinus profile effect on valve opening-closing mechanism of ePTFE valve introduced by Prof. Yamagishi of Kyoto Prefectural Medical University. This valve has bulging sinus and good clinical record for Right Ventricular Out Flow Track Reconstruction. First year research was to evaluate bulging sinus size on valve opening area change using aorta as working model. Importance of vortex inside the bulging sinus and leaflet profile shape were observed and analyzed using Dynamic PIV flow field analysis. Second year research included more finely varied bulging sinus size aiming to broaden the scope of research. Final research was to execute experiment using live-sized ePTFE valve model and facility. Similar results were obtained using new model and facility. Results also clarified that movement of vortex inside the bulging sinus of new model behaved differently.
