      Reproducibility of serial optical coherence tomography measurements for lumen area and plaque components in humans (The CLI-VAR [Centro per la Lotta Contro l’Infarto-variability] II study)
      Frequency-domain optical coherence tomography (FD-OCT) is a promising intracoronary imaging technique to study atherosclerosis. Indeed, its unprecedented spatial resolution allows the assessment of fibrous cap thickness, lipid pool and features of plaque vulnerability. Aim of this study was to determine the reproducibility of the in vivo FD-OCT measurements of lumen area and plaque components in serial studies. Twenty-six patients undergoing FD-OCT assessment of intermediate lesion during coronary angiography were included ...

      Comparative analysis method of permanent metallic stents (XIENCE) and bioresorbable poly-L-lactic (PLLA) scaffolds (Absorb) on optical coherence tomography at baseline and follow-up
      Aims: Fully bioresorbable Absorb poly-L-lactic-acid (PLLA) scaffolds (Abbott Vascular, Santa Clara, CA, USA) are a novel approach for the treatment of coronary narrowing. Due to the translucency of the material (PLLA), the optical coherence tomography (OCT) measurement methods used in the ABSORB trials were unique but not applicable for permanent metallic stents. When the Absorb scaffold and metallic stents are compared in the context of randomised trials, it is challenging ...

      Optical Coherence Tomography for Characterization of Cardiac Allograft Vasculopathy in Late Survivors of Pediatric Heart Transplantation
      Background Optical coherence tomography (OCT) has been shown to reliably detect cardiac allograft vasculopathy (CAV). In recent studies performed in adult heart transplant (HTx) recipients, OCT revealed the presence of vulnerable plaques and complicated coronary artery lesions, thus challenging the current concept that CAV disease is a diffuse concentric and fibrosing vasculopathy. The aim of our study was to characterize CAV by OCT in a young population of HTx recipients ...

      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 ...

      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 ...

      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 ...

      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 ...

      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 ...

      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 ...

      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 ...
