Predictive factors of re-restenosis after repeated sirolimus-eluting stent implantation for SES restenosis and clinical outcomes after percutaneous coronary intervention for SES restenosis.

Sirolimus-eluting stent (SES) is established to be effective in reducing restenosis. Repeat revascularization, however, is still required in up to 5-8% of patients. In this study, we analyzed clinical and angiographic variables that might be related with SES re-restenosis and variables related with re-restenosis after repeat SES implantation for SES restenosis.
