    3. Error propagation in the characterization of atheromatic plaque types based on imaging

      Error propagation in the characterization of atheromatic plaque types based on imaging
      Imaging systems transmit and acquire signals and are subject to errors including: error sources, signal variations or possible calibration errors. These errors are included in all imaging systems for atherosclerosis and are propagated to methodologies implemented for the segmentation and characterization of atherosclerotic plaque. In this paper, we present a study for the propagation of imaging errors and image segmentation errors in plaque characterization methods applied to 2D vascular images ...

    4. Optical Coherence Tomography for the Assessment of Coronary Artery Disease

      Optical Coherence Tomography for the Assessment of Coronary Artery Disease
      Angiography remains the gold standard for assessment of atherosclerotic impairment of coronary arteries and for guidance of coronary intervention. Angiography, as a main limitation, only depicts the luminal narrowings caused by coronary plaques, without showing the structures located beneath, such as the atherosclerotic lesions or the vessel wall. Intravascular imaging modalities are currently adopted to circumvent angiographic limitations. Optical coherence tomography (OCT)) is a novel imaging technique that uses infrared ...

    5. Impact of drug-eluting balloon (pre- or post-) dilation on neointima formation in de novo lesions treated by bare-metal stent: the IN-PACT CORO trial

      Impact of drug-eluting balloon (pre- or post-) dilation on neointima formation in de novo lesions treated by bare-metal stent: the IN-PACT CORO trial
      The efficacy of DEB in modifying the high restenosis risk associated with BMS implantation is doubtful. Optical coherence tomography (OCT) may allow precise assessment of neointimal formation after stent implantation. We performed a single-center, prospective, 1:2 randomized trial comparing BMS implantation alone (BMS group) vs. additional DEB (DEB group). DEB patients were further randomized 1:1 to DEB before stenting (pre-DEB group), or after stenting (post-DEB group). Primary endpoint ...

    6. New techniques of intravessel imaging in coronary atherosclerosis

      New techniques of intravessel imaging in coronary atherosclerosis
      Intravascular imaging modalities are currently adopted to circumvent angiographic limitations. The present overview is aimed at describing the principal techniques used by an interventional cardiologist to assess both coronary atherosclerotic plaques and stent deployment results. Optical coherence tomography (OCT), intravascular ultrasound (IVUS), and near-infrared spectroscopy are currently available to address these issues. These techniques are characterized by specific advantages and limitations, making each of those applicable for specific purposes. Offline ...

    7. Optical coherence tomography features of angiographic complex and smooth lesions in acute coronary syndromes

      Optical coherence tomography features of angiographic complex and smooth lesions in acute coronary syndromes
      Plaque rupture (PR) and superimposed thrombosis have been shown as the most frequent underlying substrate in acute coronary syndromes (ACS). Coronary angiography is a luminogram not able to define in vivo features of the culprit plaques. The aim of the study was to use optical coherence tomography (OCT) to investigate the pathology underlying complex (CL) and non-complex angiographic lesions (NCL). We retrospectively enrolled 107 ACS patients admitted to our institution ...

    8. Plaque rupture and intact fibrous cap assessed by optical coherence tomography portend different outcomes in patients with acute coronary syndrome

      Plaque rupture and intact fibrous cap assessed by optical coherence tomography portend different outcomes in patients with acute coronary syndrome
      Aims Patients presenting with acute coronary syndrome (ACS) may have different plaque morphologies at the culprit lesion. In particular, plaque rupture (PR) has been shown as the more frequent culprit plaque morphology in ACS. However, its prognostic value is still unknown. In this study, we evaluated the prognostic value of PR, compared with intact fibrous cap (IFC), in patients with ACS. Methods and results We enrolled consecutive patients admitted to ...

    9. Comparison of Strut Coverage at Six Months by Optical Coherence Tomography with Everolimus Eluting Stent or Bare-Metal Stent Restenosis –vs- Stenosis of Non-Stented Atherosclerotic Narrowing (from the DESERT Study)

      Comparison of Strut Coverage at Six Months by Optical Coherence Tomography with Everolimus Eluting Stent or Bare-Metal Stent Restenosis –vs- Stenosis of Non-Stented Atherosclerotic Narrowing (from the DESERT Study)
      Incomplete struts coverage is a predictor of late stent thrombosis after drug eluting stent (DES) implantation in atherosclerotic lesions. The process of struts coverage in DES implanted for bare-metal stent (BMS) restenosis has never been described. Thirty-two patients with stable coronary artery disease were consecutively selected, 11 with BMS restenosis (group A) and 21 with de-novo atherosclerotic lesions (group B). All patients underwent everolimus eluting stent implantation; coronary angiography and ...

    10. Optical Coherence Tomography Assessment and Quantification of Intracoronary Thrombus: Status and Perspectives

      Optical Coherence Tomography Assessment and Quantification of Intracoronary Thrombus: Status and Perspectives
      Coronary angiography is the golden standard imaging technique in interventional cardiology and it is still widely used to guide interventions. A major drawback of this technique, however, is that it is inaccurate in the evaluation and quantification of intracoronary thrombus burden, a critical prognosticator and predictor of intraprocedural complications in acute coronary syndromes. The introduction of optical coherence tomography (OCT) holds the promise of overcoming this important limitation, as near-infrared ...

      Identification and quantification of macrophage presence in coronary atherosclerotic plaques by optical coherence tomography
      Aims Vulnerable plaques are characterized by a high macrophage content. We investigated the optical coherence tomography (OCT) capability of identifying coronary plaque macrophage presence using tissue property indexes. Methods and results Fifteen epicardial coronary arteries were imaged by OCT and subsequently analysed by histology. Correlating OCThistological sections were identified and regions of interest (ROIs) were selected on both atherosclerotic plaques and normal appearing vessel tracts. OCT-derived tissue property indexes named ...

      Dual role of circulating endothelial progenitor cells in stent struts endothelialisation and neointimal regrowth: a substudy of the IN-PACT Coro trial
      Background Endothelialisation is a crucial event after percutaneous coronary intervention (PCI). Endothelial progenitor cells (EPC) are bone marrow derived elements with reparative properties. We aimed to assess the relationship between circulating EPC levels and stent neointimal hyperplasia (NIH) using frequency domain optical coherence tomography (FD-OCT). Methods Patients undergoing elective PCI to native vessels and randomized to bare metal stent (BMS) alone versus BMS plus drug coated balloon (DCB) were included ...

      Quantification of manual thrombus removal in patients with acute coronary syndromes: a study exploiting serial frequency domain-optical coherence tomography
      Aims: Thrombus aspiration is useful in improving myocardial reperfusion in comparison to conventional percutaneous coronary intervention in patients with acute myocardial infarction. Nonetheless, assessment of thrombus aspiration efficacy is lacking. Aim of this study was to quantify by frequency domain optical coherence tomography (OCT) the amount of thrombus removal in patients with acute coronary syndromes undergoing manual thrombus aspiration, correlating it with the actual size of the retrieved material. Methods ...
