Why the study?
What is the long-term neointimal stent coverage and rate of thrombus formation after sirolimus-eluting stent implantation?
What is the long-term neointimal stent coverage and rate of thrombus formation after sirolimus-eluting stent implantation?
Coronary angioscopy reveals that sirolimus-eluting stents can have incomplete neointimal coverage and subclinical thrombus formation up to 2 years post-implantation.
May warrant caution on early DAPT cessation after sirolimus-eluting stents; leaves open optimal surveillance and therapy duration in prospective studies.
Neointimal growth inside the SES progressed heterogeneously. Uncovered struts persisted in 20% of the patients for up to 2 years and subclinical thrombus formation was not a rare phenomenon.
