OPtical Coherence Tomography Guided Coronary Stent IMplantation Compared to Angiography: A Multicenter Randomized TriaL in PCI
AIMS: Randomized trials have demonstrated improvement in clinical outcomes with intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) compared with angiography-guided PCI. The ILUMIEN III trial demonstrated non-inferiority of an optical coherence tomography (OCT)- versus IVUS-guided PCI strategy in achieving similar post-PCI lumen dimensions. ILUMIEN IV is a large-scale, multicenter, randomized trial designed to demonstrate the superiority of OCT- versus angiography-guided stent implantation in patients with high-risk clinical characteristics (diabetes ...Read Full Article -
Clinical outcomes of calcified nodules detected by optical coherence tomography
Aims: The goal of the present post hoc analysis of the CLIMA registry was to establish the relationship between calcified nodules (CNs) with (CND) or without (CNWD) disruption of the superficial intimal fibrous layer and one-year occurrence of target lesion myocardial infarction (MI) and/or cardiac death. Methods and results: CND and CNWD were identified based on the presence or absence of superficial irregularities indicative of disruption of the intimal ...Read Full Article -
Prevalence and quantitative assessment of macrophages in coronary plaques
Although optical coherence tomography (OCT) proved to be able to identify macrophage clusters, there are no available data on the possibility to obtain reproducible measurements of their circumferential extension and location. The purpose of the present post-hoc analysis of the CLIMA study was to revise the clinical and demographic variables of patients having coronary plaques with macrophages and to investigate the reproducibility of their quantitative assessment. A total of 577 ...Read Full Article -
Comparison between different approaches to evaluate fibrous cap thickness in sequential OCT studies
BACKGROUND: In this in vivo human study we tested the reproducibility for optical coherence tomography (OCT) assessment of lumen area (LA) and plaque components measurements, such as lipid arc extension and fibrous cap thickness (FCt). METHODS: We tested the variability of LA, lipid arc and FCt assessments in two repeated OCT pullbacks from the same diseased coronary segment matched using fiduciary anatomical landmarks. In particular, for the reliability of minimal ...Read Full ArticleMentions: Francesco Prati -
Optical coherence tomography assessment of macrophages accumulation in non-ST-segment elevation acute coronary syndromes
Aims To investigate in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) the prevalence and the features of optical coherence tomography (OCT)-detected macrophages accumulation in culprit plaques as compared with nonculprit plaques (NCP). Methods The study is a post-hoc analysis of a prospective study aimed at evaluating the relationship between aortic inflammation as assessed by 18 F-fluorodeoxyglucose-PET and features of coronary plaque vulnerability as assessed by OCT. We enrolled ...Read Full Article -
Effects of stent postdilatation during primary PCI for STEMI: Insights from coronary physiology and optical coherence tomography
Objectives This study aimed to assess the impact of stent optimization by NC‐balloon postdilatation (PD) during primary‐PCI for STEMI with the use of coronary physiology and intracoronary imaging. Methods This was a prospective observational study ( ClinicalTrials.gov :NCT02788396). Optical coherence tomography (OCT) and physiological measurements were performed immediately before and after PD with the operators blinded to all measurements. The index of microcirculatory resistance (IMR), coronary flow reserve ...Read Full ArticleMentions: Francesco Prati -
A broken promise: 4-year optical coherence tomography follow-up of a bioresorbable vascular scaffold
Recently, concerns about the safety and efficacy of the Absorb BVS were derived form several studies and technical limitations have emerged by clinical practics, such asRead Full Article -

The lesson of ‘the butler didn’t do it!’. Role of optical coherence tomography for going beyond appearance
Since 1893 with Sir Arthur Conan Doyle's "The Adventure of Musgrave Ritual", the butler has become an example of feloniously coming out as a primary villain of every mystery story...Read Full ArticleMentions: Francesco Prati -
Role of optical coherence tomography for distal left main stem angioplasty
Objective The objective is to analyze the acute and midterm angiographic outcome of percutaneous treatment of left main coronary stem (LM‐PCI) guided by optical coherence tomography (OCT). Background LM‐PCI is a complex procedure, and several anatomical factors may impair its outcome. Intravascular imaging is emerging as a useful tool to guide the procedure. Methods We conducted a retrospective analysis of patients undergoing LM‐PCI at three European centers ...Read Full Article -
Clinical use of intracoronary imaging. Part 2: acute coronary syndromes, ambiguous coronary angiography findings, and guiding interventional decision-making: an expert consensus document of the European Association of Percutaneous Cardiovascular Intervent
This consensus document is the second of two reports summarizing the views of an expert panel organized by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) on the clinical use of intracoronary imaging including intravascular ultrasound (IVUS), optical coherence tomography (OCT), and near infrared spectroscopy (NIRS)-IVUS. Beyond guidance of stent selection and optimization of deployment, invasive imaging facilitates angiographic interpretation and may guide treatment in acute coronary syndrome. Intravascular ...Read Full Article -
Relationship between coronary plaque morphology of the left anterior descending artery and 12 months clinical outcome: the CLIMA study
Aims The CLIMA study, on the relationship between c oronary p l aque morphology of the left anter i or descending artery and twelve m onths clinic a l outcome, was designed to explore the predictive value of multiple high-risk plaque features in the same coronary lesion [minimum lumen area (MLA), fibrous cap thickness (FCT), lipid arc circumferential extension, and presence of optical coherence tomography (OCT)-defined macrophages] as detected ...Read Full Article -

Flying through the coronary easily
Optical coherence tomography (OCT) has been waived as a breakthrough in coronary imaging. With its superb resolution in the range of 1020 m, OCT has proven to be a valuable technique in guiding coronary interventions [13]. Apart from this, among other intracoronary technical solutions, OCT certainly has the greatest potential in studying atherosclerosis in vivo, and identifying subjects with vulnerable lesions which leave patients prone to developing hard coronary events ...Read Full ArticleMentions: Francesco Prati
