title: Role of new sirolimus self-apposing stent in coronary interventions.
abstract: Device technology in interventional cardiology is continuously evolving. Self-expandable (SE) coronary artery stents were the first device to be implanted within a human coronary artery. However, because of their initial limitations, balloon-expandable (BE) stents were predominantly developed and used in the last 30 years. Unfortunately, in challenging anatomical settings such as bifurcation lesions, large, ectatic or aneurysmal vessels, tapered vessels or vasoconstricted arteries, outcomes with BE stents are not always optimal. The Stentys (Stentys SA, Paris, France) SE nitinol stents were initially developed for the treatment of coronary bifurcation lesions. The understanding of the underlying mechanism involved in incomplete stent apposition and subsequent stent thrombosis led to the introduction of self-apposing stents in the treatment of acute coronary syndrome in order to overcome the limitations of drug-eluting stents in presence of high thrombus burden. In this regard, Stentys allows a progressive stent expansion which could reduce the rates of incomplete stent apposition by conforming to vascular remodeling. Enhancing the advantages of this technology by adding the release of an antiproliferative drug to prevent restenosis is even more attractive and potentially effective. Recently, the results of the new Stentys sirolimus-eluting stent have been reported. This article provides an overview of the pathobiological rational, device characteristics and results of the new Stentys self-expandable sirolimus-eluting stent.
