Ultra-thin strut cobalt chromium bare metal stent usage in a complex real-world setting. (SOLSTICE Registry)

Abstract

Aim To report clinical follow-up at 6 months after implantation of the ultra-thin strut cobalt chromiumSolarFlex stent in a real-world setting. Methods and results Patients (n=240) with single or multiple vessel coronary artery disease undergoing percutaneous coronary intervention (PCI) at four sites in Europe were enrolled in the SOLSTICE (SolarFlex Stent in Routine Clinical Practice) registry. Follow-up at 6 months was 100%. Diabetes was present in 29% of the patients, 30% presented with acute myocardial infarction and 17% had unstable angina. Of the patients, 27% had previously undergone PCI or coronary artery bypass surgery. Lesion complexity was high (50% B2+C type lesions). Device success was achieved in 99.7% of cases and themajor adverse cardiac event (MACE) ratewas 5.8% at 6 months of follow-up. Target lesion revascularisation (TLR) was 5.0% at 6 months. Conclusions The SOLSTICE registry showed that in a complex real-world setting the SolarFlex bare metal stent, with ultra-thin struts and customised scaffolding, provided low clinical MACE and TLR rates. These results provide support for the use of the latest generation bare metal stent in contemporary European practice.
