Aims: The aim of this randomised study is to evaluate the efficacy and safety of a new bare metal stents (BMS) with thin struts and a novel passive coating as compared to current standard BMS. Methods and results: We designed an international, multicentre, randomised trial planned to include 160 patients assigned to receive either the titanium-nitride coated MAR-tyn stent (International Biomedical Systems, Trieste, Italy) or the Vision stent (Abbott Vascular, Abbott Laboratories, Abbott Park, IL, USA). Patients with left main or bypass graft disease, complex coronary lesions, needing treatment of multiple lesions, with recent myocardial infarction, prior BMS in or within 5 mm of the target lesion, left ventricular ejection fraction ≤25% and at increased bleeding risk are excluded. All patients are treated with dual antiplatelet therapy for two months. The primary endpoint is in-stent late luminal loss (LL) at 6-month follow-up angiography. Secondary endpoints are the incidence of major adverse cardiovascular events (MACE) and stent thrombosis over 12 months after randomisation. Patients' enrolment is open in all centres. Conclusions: This study will address the important question of safety and efficacy of a novel, inert and highly compatible passive coating on a thin-strut BMS with a great potential to be superior to a non-coated widely used BMS.
