Assessment of Heterogeneity of Strut-Level Neointima Hyperplasia After Stent Implantation by Optical Coherence Tomography
Background: Optical coherence tomography (OCT) permits a highly accurate NIH assessment at each strut level within a cross-section. The aim of this study is to evaluate heterogeneity of NIH among different stents.
Methods: Patients enrolled in ODESSA were assessed. ODESSA was a prospective randomized trial designed to evaluate strut coverage of overlapped (OLP) vs. non-OLP stent segments for the treatment of de-novo, native coronary artery stenosis with four different stent types: Sirolimus-eluting stent (SES); Paclitaxel-eluting stent (PES); Zotarolimus-eluting stent (ZES); and Liberte BMS (BMS). Distance between strut and lumen was measured in every 5 frames (0.3mm) along the stented ...
