First clinical experience with Stenty’s Xposition shows 100% implantation success

104

The findings of the first Xposition (Stentys) clinical experience, as part of the SETUP trial, have been presented at the EuroPCR 2015 conference (19–22 May, Paris, France). The results of this study were also published in the online edition of EuroIntervention.

Xposition S is a sirolimus-eluting self-apposing stent. It is delivered by a unique stent delivery system that closely replicates conventional stent implantation techniques: a small balloon peels the sheath containing the stent to release it precisely at the intended location.

The SETUP study was a prospective, single-arm first-in-man study performed in two Dutch centres (Academic Medical Centre, Amsterdam, and Albert Schweitzer Hospital, Dordrecht) to evaluate the feasibility of the use of the novel Xposition S in de novo coronary lesions. The study enrolled 25 patients and demonstrated 100% technical and angiographic success rates without longitudinal geographical miss on quantitative coronary angiography (QCA). Stent strut malapposition as assessed by optical coherence tomography (OCT) was very low (0.6%) at the end of the procedure.

Principal investigator Karel Koch, from AMC hospital, stated, “Stentys’ novel balloon delivery system allowed for easy and accurate deployment of all stents at the target lesions, which of note, were performed with real-world lesion complexities, including ostial lesions, highly calcified lesions and lesions with high thrombus burden. We noticed significant improvement over the previous system and see how Xposition S could advance the quality of treatment for heart attack patients or patients with variable artery anatomy.”
