TLDR
This comprehensive overview is aimed to summarize different applicable definitions used by different research groups in plaque and stent analysis using OCT and presents readers with a panoramic view to select the best definition of OCT measurement for one's own study purpose.Abstract:
Optical coherence tomography (OCT) is the current state-of-the-art intracoronary imaging modality that allows visualization of detailed morphological characteristics of both atherosclerotic plaque and stent. So far, three expert review documents have been released for standardization of OCT image anread more

Journal ArticleDOI
A new optical coherence tomography-based calcium scoring system to predict stent underexpansion.
Akiko Fujino,Gary S. Mintz,Mitsuaki Matsumura,Tetsumin Lee,Song-Yi Kim,Masahiro Hoshino,Eisuke Usui,Taishi Yonetsu,Elizabeth Haag,Richard Shlofmitz,Tsunekazu Kakuta,Akiko Maehara +11 more
TL;DR: An OCT-based calcium scoring system can help to identify lesions that would benefit from plaque modification prior to stent implantation and was an independent predictor of stent underexpansion.

TL;DR: PE was the underlying mechanism in one-fourth of STEMI and was associated with less microvascular damage after PCI, while CN was characterized by superficial large calcium and negative remodeling.

Optical coherence tomography imaging during percutaneous coronary intervention impacts physician decision-making: ILUMIEN I study.
William Wijns,Junya Shite,Michael R. Jones,Stephen W.L. Lee,Matthew J. Price,Franco Fabbiocchi,Emanuele Barbato,Takashi Akasaka,Hiram G. Bezerra,David R. Holmes +9 more
TL;DR: Physician decision-making was affected by OCT imaging prior to PCI in 57% and post-PCI in 27% of all cases and the association with post- PCI FFR values and early clinical events is reported.

TL;DR: Irregular protrusion and small minimal stent area were independent predictors of 1-year device-oriented clinical end points, which were primarily driven by target lesion revascularization.

TL;DR: Although a higher prevalence of post-PCI stent malapposition, tissue protrusion, and edge dissections was detected by OCT, the rates of major malappposition, tissue prolapse, and dissections were similar after OCT- and IVUS-guided stenting.

TL;DR: Objective OCT criteria are highly sensitive and specific for characterizing different types of atherosclerotic plaques in vitro and will provide a basis for the interpretation of intracoronary OCT images obtained from patients.

Macrophage infiltration in acute coronary syndromes. Implications for plaque rupture.
TL;DR: Macrophage-rich areas are more frequently found in patients with unstable angina and non-Q-wave myocardial infarction, which suggests that macrophages are a marker of unstable atherosclerotic plaques and may play a significant role in the pathophysiology of acute coronary syndromes.
