S-FLEX Netherlands Registry: Prospective Evaluation of the Supraflex Family Sirolimus-eluting Coronary Stent System

To overcome the potential drawback of the durable polymer a new generation of drug-eluting stent (DES) with a biodegradable polymer has been designed. The first-generation sirolimus-eluting or paclitaxel-eluting stents have a polymer release of antiproliferative drugs from a stainless steel stent platform. More recently, second generation DES have been developed not only to improve long-term DES safety but also to facilitate the procedure by using a cobalt-chromium (Co-Cr) stent platform. Co-Cr is stronger and more radiopaque than stainless steel, and thus allows strut thickness and total stent volume to be reduced while maintaining radial strength leading to a more flexible and deliverable stent platform. The Sahajanand Medical Technologies Pvt. Ltd. (SMT) has developed sirolimus-eluting stent that contain a biodegradable polymer coating and a Co-Cr stent platform. The purpose of this registry is to evaluate the Supraflex Family sirolimus-eluting stent in a 'real-world' patient population, in order to determine the safety and efficacy of the stent in wider usage.
