Angioscopic findings of delayed healing at sites of sirolimus-eluting stent overlap after 21-month implantation

Treatment of de novo coronary stenosis with sirolimus-eluting stents is associated with very low rates of target lesion revascularization and other major adverse cardiac events in the short-term after implantation, but a definite frequency of late-stent thrombosis (LST) over a long-term follow-up has become evident. One of the predictors of LST is stent overlap. We reported the angioscopic findings of very delayed healing at sites of sirolimus-eluting stent overlap 21 months post-implantation.
