Very long-term serial luminal changes after sirolimus-eluting stent implantation and progression process of very late stent failure

Progression of in-stent luminal narrowing did not attenuate beyond 5 years after SES implantation. In very late SES failure, stent-related ACS lesions showed gradual luminal narrowing and subsequent rapid progression beyond 5 years, whereas non-ACS lesions had progressive luminal narrowing within 5 years.
