The present study aimed to evaluate the clinical performance, in the daily practice of a busy catheterization laboratory, of a novel drug-eluting stent (DES) built with an ultra-thin-strut metallic platform, eluting sirolimus at low doses, abluminal coated with biodegradable polymers, and mounted in a low-compliant delivery system.


Prospective, single-arm study, comprising all consecutive patients undergoing percutaneous coronary intervention (PCI) with the Inspiron™ sirolimus-eluting stent (SES) (Scitech, Aparecida de Goiania, Brazil). The primary endpoint was the occurrence of major adverse cardiac events (MACE) [cardiac death, non-PCI related myocardial infarction (MI), or target vessel revascularization (TVR)].


A total of 470 patients were included, from which 51.3% were diabetics, 33.8% had triple-vessel disease, 15.3% had heart failure, 38.9% had at least one bifurcation treated, 19.8% were treated for a bare metal stent restenosis, and 61.9% had at least one type C lesion; one or more of these features were found in 96.0%. At 300 days, the rate target lesion revascularization was 5.4% and the rate of MACE was 8.1%. The incidence of definite or probable stent thrombosis was 0.4%, with no cases between 30 and 300 days.


The novel stent is associated with excellent short and mid-term clinical outcomes in patients treated with PCI in the daily practice.
