AIM: The aim of this study was to evaluate the strut apposition and neointimal coverage of Supralimus-Core stent struts at 4 months after implantation using optical coherence tomography (OCT). METHODS: The Supralimus-Core OCT study is a retrospective, single-center study evaluating strut apposition and neointimal coverage with OCT at 4 months after stent implantation. A total of 12 patients, who had 15 stents implanted were included in the study. The OCT was obtained using a C7-XR FD-OCT (frequency-domain OCT) intravascular imaging system. Strut apposition, neointimal hyperplasia (NIH) thickness and stent coverage on each stent strut were evaluated. RESULTS: A total of 2870 struts and 1950 frames were analyzed from 15 stents. Average stent length was 29.3 mm. Average reference vessel diameter was 2.64 mm. Among 12 patients, 3 (25.0%) patients were with diabetes, 4 (26.7%) type B2 and 10 (66.7%) type C lesions. The apposed and covered struts were 2787 (97.11%), whereas malapposed and covered struts were 3 (0.10%), apposed and uncovered 49 (1.71%) and malapposed and uncovered 31 (1.08%). Mean NIH thickness was 155.1±55.2 µm. CONCLUSION: The present study suggests that Supralimus-Core stent has a favorable vascular healing pattern at 4 months after stent implantation in terms of stent-strut coverage and strut apposition. This information indicates that the Supralimus-Core stent is a promising solution for decreasing late stent restenosis and preventing stent thrombosis.
