    1. Clinical outcomes of calcified nodules detected by optical coherence tomography

      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 fibrous layer, with possible overlying local thrombus. In total, 222 CNs were found in the 1,776 non-culprit LAD plaques. CND had larger maximum calcific arc and smaller lumen area ...

    2. Prevalence and quantitative assessment of macrophages in coronary plaques

      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 patients out of 1003 undergoing OCT showed macrophage accumulation. Three groups were identified; group 1 (426 patients) without macrophages, group 2 (296) patients with low macrophage content (less than median ...

    3. Progressive growth of coronary aneurysms after bioresorbable vascular scaffold implantation: Successful treatment with OCT‐guided exclusion using covered stents

      Progressive growth of coronary aneurysms after bioresorbable vascular scaffold implantation: Successful treatment with OCT‐guided exclusion using covered stents

      The development and progressive enlargement over time of multiple saccular coronary artery aneurysms (CAA) after implantation of everolimus‐eluting stent and bioresorbable vascular scaffolds (BVS) have been reported. CAA was successfully excluded by two overlapped covered stents expanded inside a long metallic drug‐eluting stent to avoid dislodgment at the overlap point. Optical coherence tomography (OCT) was repeatedly performed to monitor CAA expansion and to guide treatment through precise measurement of aneurysm length and vessel size at the landing zone. At 10‐month follow‐up, coronary computed tomography angiography showed persistent CAA exclusion. To the best of our knowledge, this ...

    4. Comparison between different approaches to evaluate fibrous cap thickness in sequential OCT studies

      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 FCt measurement we compared four different approaches based on continuous (longitudinal) or segmental (spot) individuation of smaller thickness: 1) comparison of single minimal FCt individuated alongside all plaque extension in ...

    5. Outcomes of Optical Coherence Tomography Compared With Intravascular Ultrasound and With Angiography to Guide Coronary Stent Implantation: One-Year Results from the ILUMIEN III: OPTIMIZE PCI trial

      Outcomes of Optical Coherence Tomography Compared With Intravascular Ultrasound and With Angiography to Guide Coronary Stent Implantation: One-Year Results from the ILUMIEN III: OPTIMIZE PCI trial

      Aims: In the ILUMIEN III trial, among 450 randomised patients with non-complex lesions undergoing percutaneous coronary intervention (PCI), optical coherence tomography (OCT) guidance led to greater stent expansion than angiography guidance, similar minimal stent area compared to both intravascular ultrasound (IVUS) guidance and angiography guidance, and lower rates of uncorrected dissection and malapposition than both IVUS guidance and angiography guidance. Whether these differences impact clinical outcomes is unknown. Methods and results : OCT-guided PCI, using an external elastic lamina-based protocol, was compared to operator-directed IVUS-guided or angiography-guided PCI. Target lesion failure (TLF) and major adverse cardiovascular events (MACE) at 12 months ...

      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 by OCT. Composite of cardiac death and target segment myocardial infarction was the primary clinical endpoint. Methods and results From January 2013 to December 2016, 1003 patients undergoing OCT evaluation ...

    7. Activation of Nrf2/HO-1 Pathway and Human Atherosclerotic Plaque Vulnerability:an In Vitro and In Vivo Study

      Activation of Nrf2/HO-1 Pathway and Human Atherosclerotic Plaque Vulnerability:an In Vitro and In Vivo Study

      Reactive oxygen species (ROS) induce nuclear factor erythroid 2–related factor 2 (Nrf2) activation as an adaptive defense mechanism, determining the synthesis of antioxidant molecules, including heme-oxygenase-1 (HO-1). HO-1 protects cells against oxidative injury, degrading free heme and inhibiting ROS production. HO-1 is highly expressed in macrophages during plaque growth. Macrophages are morpho-functionally heterogeneous, and the prevalence of a specific phenotype may influence the plaque fate. This heterogeneity has also been observed in monocyte-derived macrophages (MDMs), a model of macrophages infiltrating tissue. The study aims to assess oxidative stress status and Nrf2/HO-1 axis in MDM morphotypes obtained from healthy ...

      Long-term consequences of optical coherence tomography findings during percutaneous coronary intervention: the centro per la lotta contro l\'infarto - optimization of percutaneous coronary intervention (cli-opci) late study

      Aims: The role of intra-procedural Optical Coherence Tomography (OCT) on long-term clinical outcome of percutaneous coronary interventions (PCI) remains undefined. Methods and results: In the context of the multicenter Centro per la Lotta contro l’Infarto-Optimisation of Percutaneous Coronary Intervention (CLI-OPCI) registry, we compared long-term PCI outcome of 1211 patients from 13 independent OCT-experienced centers according to end-procedural OCT findings. OCT assessment revealed suboptimal stent implantation in 30.9% of lesions, with increased prevalence in patients experiencing device-oriented cardiovascular events (DoCE) (52.8% vs. 28.0%, p<0.001). At median follow-up of 833 (quartiles 415-1447) days, in-stent minimum lumen ...

    10. Optical coherence tomography compared with intravascular ultrasound and with angiography to guide coronary stent implantation (ILUMIEN III: OPTIMIZE PCI): a randomised controlled trial

      Optical coherence tomography compared with intravascular ultrasound and with angiography to guide coronary stent implantation (ILUMIEN III: OPTIMIZE PCI): a randomised controlled trial

      Background Percutaneous coronary intervention (PCI) is most commonly guided by angiography alone. Intravascular ultrasound (IVUS) guidance has been shown to reduce major adverse cardiovascular events (MACE) after PCI, principally by resulting in a larger postprocedure lumen than with angiographic guidance. Optical coherence tomography (OCT) provides higher resolution imaging than does IVUS, although findings from some studies suggest that it might lead to smaller luminal diameters after stent implantation. We sought to establish whether or not a novel OCT-based stent sizing strategy would result in a minimum stent area similar to or better than that achieved with IVUS guidance and better ...

    11. Optical coherence tomography imaging during percutaneous coronary intervention impacts physician decision-making: ILUMIEN I Study

      Optical coherence tomography imaging during percutaneous coronary intervention impacts physician decision-making: ILUMIEN I Study

      Aims ILUMIEN I is the largest prospective, non-randomized, observational study of percutaneous coronary intervention (PCI) procedural practice in patients undergoing intra-procedural pre- and post-PCI fractional flow reserve (FFR) and optical coherence tomography (OCT). We report on the impact of OCT on physician decision-making and the association with post-PCI FFR values and early clinical events. Methods and results Optical coherence tomography and documentary FFR were performed pre- and post-PCI in 418 patients (with 467 stenoses) with stable or unstable angina or NSTEMI. Based on pre-PCI OCT, the procedure was altered in 55% of patients (57% of all stenoses) by selecting different ...
