Abstract:
Despite technological advances in interventional cardiology during the last decades, many concerns remain regarding the narrowing and occlusion of the in-stent area. Particularly, polymer materials pose several problems, including chronic arterial inflammation, impaired arterial healing, and stent thrombosis. To avoid these complications, we invented the TIGEREVOLUTION stent with a cobalt–chromium alloy-based stent platform deposited with N-TiO 2 film, which has demonstrated good biocompatibility. As this stent is not coated with polymer, it is expected to have decreased risk of stent thrombosis. Patient concerns: A 62-year-old Korean man visited our department because of angina. We commenced coronary angiography (CAG). Diagnosis: CAG revealed critical stenosis in the mid-portion of the right coronary artery, with a minimum lumen area of 1.08mm 2 on optical coherence tomography (OCT). Intervention: Percutaneous coronary intervention was performed with implantation of a novel 3.5 × 26-mm polymer-free everolimus-eluting stent using nitrogen-doped titanium dioxide film (TIGEREVOLUTION ® stent). Post-percutaneous coronary intervention OCT showed good stent expansion and apposition, and the patient was discharged successfully and uneventfully. Outcomes: Eight months later, follow-up coronary angiography demonstrated good stent patency with no definitive evidence of in-stent restenosis, with thin stent strut coverage demonstrated on OCT. Lessons: We report the first case of TIGEREVOLUTION stent implantation with follow-up OCT at 8 months.
