    3. Role of optical coherence tomography in identifying sub-optimal stent positioning and predicting major adverse cardiac events in a comparative study with angiography: a CLIO-OPCI II sub-study

      Role of optical coherence tomography in identifying sub-optimal stent positioning and predicting major adverse cardiac events in a comparative study with angiography: a CLIO-OPCI II sub-study
      Background Quantitative coronary angiography (QCA) is the gold standard for evaluating correct stenting, despite its limitation in recognizing features indicative of suboptimal deployment. This subanalysis of the CLI-OPCI II registry addressed the role of optical coherence tomography (OCT) to verify whether suboptimal OCT deployment occurs in the presence of an optimal angiographic result. Patients and methods We retrospectively analyzed 125 lesions in the 105 patients with major adverse cardiac events ...

      Long-tem 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 lInfarto-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 ...

    5. Clinical Outcomes Following Intravascular Imaging-Guided Versus Coronary Angiography–Guided Percutaneous Coronary Intervention With Stent Implantation

      Clinical Outcomes Following Intravascular Imaging-Guided Versus Coronary Angiography–Guided Percutaneous Coronary Intervention With Stent Implantation
      Objectives The authors sought to explore the comparative clinical efficacy of different imaging modalities for guiding percutaneous coronary interventions (PCI). Background Coronary angiography (CA) is the standard imaging modality for intraprocedural guidance of PCI. Intracoronary imaging techniques, including intravascular ultrasound (IVUS) and optical coherence tomography (OCT), can overcome some limitations of CA. Methods Comprehensive hierarchical Bayesian network meta-analysis of randomized clinical trials and adjusted observational studies comparing clinical outcomes of ...

    6. Vascular response and healing profile of everolimus-eluting bioresorbable vascular scaffolds for percutaneous treatment of chronic total coronary occlusions: A one-year optical coherence tomography analysis from the GHOST-CTO registry

      Vascular response and healing profile of everolimus-eluting bioresorbable vascular scaffolds for percutaneous treatment of chronic total coronary occlusions: A one-year optical coherence tomography analysis from the GHOST-CTO registry
      Background Bioresorbable vascular scaffolds (BVS) have been heralded with potential benefits that are especially desired in long lesions, including chronic total occlusions (CTOs). Procedural feasibility and mid-term outcomes of BVS in CTOs have been reported. However, there is still a paucity of data regarding the vascular and healing response to BVS in CTOs evaluated by optical coherence tomography (OCT). Methods This study included prospectively 21 patients who had a CTO ...

    7. Culprit plaque characteristics in younger versus older patients with acute coronary syndromes: An optical coherence tomography study from the FORMIDABLE registry

      Culprit plaque characteristics in younger versus older patients with acute coronary syndromes: An optical coherence tomography study from the FORMIDABLE registry
      Objectives Culprit plaque characteristics in young patients who experience an Acute Coronary Syndrome (ACS) evaluated by OCT (Optical Coherence Tomography) have to be defined. The OCT-FORMIDABLE is a multicentre retrospective registry enrolling consecutive patients with ACS who performed OCT in 9 European centres. Methods Patients were divided in two groups according to age at presentation: juvenile-ACS (age50 years) and not juvenile-ACS (age50 years). Primary end-point was the prevalence of plaque ...

    8. Intracoronary Imaging

      Intracoronary Imaging
      Two intracoronary imaging techniques are routinely available to complement angiography in the management of coronary artery disease, namely intravascular ultrasound (IVUS) and optical coherence tomography (OCT). The former has been in clinical use for 25 years and has directly informed the fundamentals of atherosclerotic plaque composition and arterial remodelling, as well as contemporary optimal stent implantation technique. 1 , 2 The latter, introduced 10 years ago, has only been more widely ...

    9. Impact of Culprit Plaque and Atherothrombotic Components on Incomplete Stent Apposition in Patients With ST-Elevation Myocardial Infarction Treated With Everolimus-Eluting Stents – An OCTAVIA Substudy –

      Impact of Culprit Plaque and Atherothrombotic Components on Incomplete Stent Apposition in Patients With ST-Elevation Myocardial Infarction Treated With Everolimus-Eluting Stents – An OCTAVIA Substudy –
      Background: The role of culprit plaque and related atherothrombotic components on incomplete stent apposition (ISA) occurrence after primary percutaneous coronary intervention (p-PCI) is unknown. Methods and Results: ST-segment elevation myocardial infarction (STEMI) patients undergoing p-PCI with an everolimus-eluting stent were prospectively investigated with optical coherence tomography (OCT) of the infarct-related artery before, after stenting and at 9 months. OCT data, aspirated thrombus and serum inflammatory biomarkers were analyzed. 114 patients ...

    10. Embolization of Fractured Bioresorbable Scaffold Struts Insights From 2- and 3-Dimensional Optical Coherence Tomography

      Embolization of Fractured Bioresorbable Scaffold Struts Insights From 2- and 3-Dimensional Optical Coherence Tomography
      A 58-year-old diabetic man underwent implantation of 3 overlapping Absorb bioresorbable vascular scaffolds (BVS) (2.5/28, 2.5/28, and 3.0/28 mm) (Abbott Vascular, Santa Clara, California) in a heavily calcified left anterior descending artery stenosis. Optical coherence tomography (OCT) revealed multiple fractures of the 3.0/28 BVS, leading to in-scaffold implantation of a zotarolimus-eluting stent (ZES) ( Figures 1A and 1B ). The 4-month angiography showed a ...

    11. Clinical Impact of OCT Findings During PCI: The CLI-OPCI II Study

      Clinical Impact of OCT Findings During PCI: The CLI-OPCI II Study
      Objectives The goal of this study was to assess the clinical impact of optical coherence tomography (OCT) findings during percutaneous coronary intervention (PCI). Background OCT provides unprecedented high-definition visualization of plaque/stent structures during PCI; however, the impact of OCT findings on outcome remains undefined. Methods In the context of the multicenter CLI-OPCI (Centro per la Lotta contro lInfartoOptimisation of Percutaneous Coronary Intervention) registry, we retrospectively analyzed patients undergoing end-procedural ...

      Cyphering the Mechanism of Late Failure of Bioresorbable Vascular Scaffolds in Percutaneous Coronary Intervention of the Left Main Coronary Artery
      A 48-year-old woman with history of multiple percutaneous coronary interventions and bypass grafting on the left anterior descending coronary artery presented with unstable angina. Coronary angiography showed a patent left internal mammary artery and de novo critical stenoses of the mid-shaft left main and the unprotected left circumflex coronary artery (LCX). Both lesions were treated with 2 nonoverlapping bioresorbable vascular scaffolds (BVS) (Absorb, Abbott Vascular, Santa Clara, California) 3.5 ...
