Do sirolimus-eluting stents maintain in-stent lumen dimensions at 4 years?
Sirolimus-eluting stents demonstrate sustained efficacy with unchanged in-stent lumen dimensions at 4 years post-implantation.
This study confirms the longevity of the optimal outcomes observed in patients treated with sirolimus-eluting Bx Velocity stents 4 years after implantation. In-stent lumen dimensions remained essentially unchanged at 4-year follow-up, particularly in the population treated with the currently available SES (SR formulation).
Sousa et al. (Tue,) studied this question.
