Angiographic and clinical results of the STENTYS Xposition S self-apposing stent. A single-center experience

Abstract

ABSTRACT Introduction and objectives: The STENTYS Xposition S stent (STENTYS S.A, Paris, France) is the only self-apposing sirolimus- eluting stent available in the market. The stent features make it useful to treat challenging lesions with proximal-distal different vessel diameter, ectasia, high thrombus burden, bifurcation lesions including the left main coronary artery or vein grafts. We describe our own experience with the use of this stent and evaluate its efficacy and safety profile. Methods: We included all consecutive patients treated with the STENTYS Xposition S from January 2018 to October 2019. All coronary lesions were quantified using QCA (quantitative coronary angiography). Results: A total of 62 lesions in 50 patients were treated with the STENTYS Xposition S. The median age of the patients was 66 years (49-92). The most common clinical presentation was ST-segment elevation acute coronary syndrome in 23 patients (46%). Ectasia and significant vessel diameter variance were the most common scenario in 72.6% of cases and bifurcation in the remaining 27.4% (2 of them in the left main coronary artery). Pre-dilatation was performed in 32 lesions (51.6%) and post-dilatation in 37 (59.7%). Angiographic success was achieved in all patients except for 1. At the median 373-day follow-up (256-439), 1 patient had an acute myocardial infarction 3 months after the percutaneous intervention and 1 patient died due to cardiac failure during admission. There were no cases of definitive stent thrombosis or target lesion revascularization. Conclusions: The STENTYS Xposition S self-apposing stent showed good angiographic and clinical outcomes in our real-world experience.
