Hybrid Sirolimus-Eluting Stents with Biodegradable Polymer Did Not Improve Angiographic Outcomes Compared to Everolimus-Eluting Stents with Durable Polymer in Treatment of Chronic Total Occlusions
Cardiovascular Research Foundation (CRF)Results from a randomized, multicenter trial failed to show non-inferiority of hybrid, ultra-thin strut sirolimus-eluting stents (Osiro SES) with a biodegradable polymer compared to thin-strut everolimus-eluting stents (Xience EES) with a durable polymer in terms of in-segment late lumen loss in successfully treated chronic total occlusions. In addition, although the rate of binary restenosis was low overall in this complex lesion subset, it was higher with the Osirio SES compared with the Xience EES.
