Background and Objectives : It has been reported that strut thickness is associated with the occurrence of in-stent restenosis. This prospective, multicenter, single-arm study was designed to evaluate the safety and efficacy of the ArthosPico stent manufactured with thin-strut cobalt-chromium alloy steel for simple de novo coronary lesions. Subjects and Methods : A total of 150 coronary lesions that were ≥3.0 mm in diameter and ≤20 mm in length, which could be covered by a single stent, were enrolled. Clopidogrel was used for 1 month. Results : Acute coronary syndrome was involved in 60.7% of patients. The right coronary artery (50.0%) was the most common target vessel. All stents were successfully deployed at the target lesions. Reference vessel diameter was 3.1±0.5 mm and lesion length was 13.6±4.6 mm. Minimal lumen diameter was increased from 1.03±0.48 to 3.04±0.49 mm after the procedure. Follow-up angiography was obtained in 117 lesions (78%). Binary restenosis was documented in 12.0% of stented segments and in 13.7% of analytic segments. Late luminal loss was found to be 0.78±0.75 mm in stented segments and 0.59±0.74 mm in analytic segments. During 7.0±2.8 months follow-up, cardiac death or non-fatal myocardial infarction occurred in 2 (1.3%) and 2 (1.3%) patients, respectively. Target lesion revascularization was performed in 11 (7.3%) patients. Conclusion : The cobalt-chromium alloy ArthosPico stent for relatively simple coronary lesions showed favorable acute and long-term outcomes in terms of very low incidence of death or myocardial infarction and a single digit rate of target lesion revascularization.
