The ESSEX (European Scimed Stent Experience) study.

The aim of the study was to assess the safety and feasibility of implantation of the Scimed Radius stent. Secondary objectives were to assess the result of stent placement by quantitative coronary angiography (QCA) and intravascular ultrasound (IVUS). The ESSEX study was a prospective, multicenter, observational study in which candidates for a single elective stent implantation, in a de novo or restenotic lesion, reference diameter 2.75–4.00 mm and target lesion 12 atm) as a determinant of clinical, QCA, and IVUS outcomes suggested no benefit or detrimental effect from optimization with high-pressure balloon inflation. Implantation of the self-expanding Radius stent is safe and efficacious. Based on registry data, clinical, angiographic, and IVUS, data comparable with modern balloon-expandable stents were obtained.
