The Ultimaster Coronary Stent System: 5-year Worldwide Experience

Newer generation drug-eluting stents have significantly improved outcomes in patients undergoing percutaneous coronary intervention by reducing the risk of restenosis and stent thrombosis. In comparison with first-generation ones, contemporary drug-eluting stents have thinner struts and more biocompatible polymers, which reduce inflammation, promote endothelialization and decrease neointimal proliferation. The Ultimaster™/Ultimaster™ Tansei™ coronary stent system is a cobalt-chromium, biodegradable polymer, sirolimus-eluting stent (Terumo, Tokyo, Japan) that received the Conformitè Européenne mark approval for clinical use in 2014/2018. This device has been the object of intense clinical evaluation in controlled randomized studies and observational registries. In this article, we analytically reviewed the available clinical data with a focus on the latest real-world evidence that demonstrates excellent performance in all of the clinical subsets.
