Background Outcomes after sirolimus-eluting stent (SES:Cypher^[○!R]) implantation remained to be elucidated in Japan. Methods and Results Among 1,070 consecutive angiographic follow-up lesions, 99 lesions underwent target lesion revascularization (TLR) with in-stent restenosis (ISR). Retrospective estimation by multivariate analysis including 50 variables showed that the ostiums of right coronary and left circumflex arteries, hemodialysis, calcification, non-direct stenting, ISR of SES, and non-eccentric lesion were the predictors of TLR. There was no documented late stent thrombosis (LST) among 2,166 lesions and very LST (VLST) among 1,423 lesions. Conclusion Further revises are needed to implant SES to these predictive lesions. LST and VLST were very rare.
