Outline of Final Research Achievements |
We evaluated a vamotion in new generation drug-eluting stent (DES) implantation, everolimus-eluting stent (EES) and biolimus-eluting stent. The BES could improve an abnormal vasomotion compared with first generation DES and EES. In immunohistological analysis, enhanced inflammatory response and adventitial Vasa Vasorum (VV) formation, which were observed in first generation DES, was significantly inhibited in BES site. Furthermore, we succeeded VV imaging in vivo by optical frequency domain imaging in pigs and even in humans.
