Successful implantation of a novel polymer-free everolimus-eluting stent using nitrogen-doped titanium dioxide film with good patency on follow-up angiography: A case report.

ABSTRACT:

Rationale

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-TiO2 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
