- Abstract
<bold>Objectives: </bold>To evaluate the safety and effectiveness of the Kaname™ cobalt-chromium (Co-Cr), thin strut, bare metal stent (BMS) system for the treatment of coronary artery lesions.<bold>Background: </bold>Despite widespread use of drug-eluting stents, a certain percentage of patients with coronary artery disease are still treated with BMS. Therefore, it is essential to evaluate their clinical performance.<bold>Methods: </bold>Two hundred eighty-two patients were enrolled in this prospective, single-arm study including a predefined subset of 79 patients with small vessels. The primary end-point was freedom from target vessel failure (TVF) at 6 months. Key angiographic and intravascular ultrasound (IVUS) end-points were late loss, diameter stenosis, binary restenosis, and neointimal hyperplasia volume.<bold>Results: </bold>Freedom from TVF at 6 months was 93.3% and at 1 year 90.8% in total population, and 92.4% and 87.3% in small vessels, respectively. Clinically driven target lesion revascularization (TLR) rates at 6 and 12 months were 4.3% and 6.4% in total population, and 3.8% and 7.6% in small vessels, respectively. At 6 months in-stent late loss was 0.75 ± 0.43 mm and binary restenosis rate was 16.9% in total population, and 0.64 ± 0.40 mm and 26.1% in small vessels, while IVUS assessed neointimal hyperplasia volume at 6 months was 128.9 ± 42.6 mm(3) for total population. There were no definite and probable stent thromboses up to 12 months.<bold>Conclusions: </bold>Results indicate good safety and effectiveness of the Kaname™ stent with clinically equivalent results in small and larger vessels, as such providing useful treatment option for patients with ischemic heart disease considered for BMS implantation.
