    1. EuroIntervention Automated characterisation of lipid core plaques in vivo by quantitative optical coherence tomography tissue type imaging

      EuroIntervention Automated characterisation of lipid core plaques in vivo by quantitative optical coherence tomography tissue type imaging
      Aims: Qualitative criteria for plaque tissue characterisation by OCT are well established, but quantitative methods lack systematic validation in vivo . High optical attenuation coefficient t has been associated with unstable plaque features, such as lipid core. The purpose of this study was to validate optical coherence tomography (OCT) attenuation imaging for tissue characterisation in vivo , specifically to detect lipid core in coronary atherosclerotic plaques, and to evaluate quantitatively the ability ...

    2. Safety of optical coherence tomography in daily practice: a comparison with intravascular ultrasound

      Safety of optical coherence tomography in daily practice: a comparison with intravascular ultrasound
      Aims Previous studies have reported the safety and feasibility of both time-domain optical coherence tomography (TD-OCT) and Fourier-domain OCT (FD-OCT) in highly selected patients and clinical settings. However, the generalizability of these data is limited, and data in unselected patient populations reflecting a routine cathlab practice are lacking. We compared safety of intracoronary FD-OCT imaging to intravascular ultrasound (IVUS) imaging in a large real-world series of consecutive patients who underwent ...

    3. An Unusual Complication After Bioresorbable Scaffold Implantation Visualization of Intramural Hematoma by Optical Coherence Tomography

      An Unusual Complication After Bioresorbable Scaffold Implantation Visualization of Intramural Hematoma by Optical Coherence Tomography
      A 68-year-old man was treated in our catheterization laboratory for ST-segment elevation myocardial infarction. He had undergone 3.5 18-mm bioresorbable vascular scaffold (BVS) implantation in the proximal left anterior descending coronary artery for stable angina in another institution 2 days before. At presentation, angiography showed a filling defect located 5 mm distally to the scaffolded segment ( Figure 1A ). An attempt at thrombus aspiration was performed, without retrieving any aspiration ...

    4. Utility of Optical Coherence Tomography Imaging with Angiographic Co-registration for the Guidance of Percutaneous Coronary Intervention

      Utility of Optical Coherence Tomography Imaging with Angiographic Co-registration for the Guidance of Percutaneous Coronary Intervention
      Intracoronary optical coherence tomography (OCT) is a light-based imaging modality able to visualise with high resolution (~10 m) the vascular morphology and the acute and chronic effects of intervention with intracoronary devices. 1,2 OCT could therefore find application in the guidance of percutaneous coronary intervention (PCI), allowing a thorough preprocedural lesion assessment, which enables accurate device sizing, selection of the vessel segment requiring treatment, and, thus, efficient planning of ...

    5. Multimodality Intra-Arterial Imaging Assessment of the Vascular Trauma Induced by Balloon-Based and Nonballoon-Based Renal Denervation Systems

      Multimodality Intra-Arterial Imaging Assessment of the Vascular Trauma Induced by Balloon-Based and Nonballoon-Based Renal Denervation Systems
      Background Renal denervation is a new treatment considered for several possible indications. As new systems are introduced, the incidence of acute renal artery wall injury with relation to the denervation method is unknown. We investigated the acute repercussion of renal denervation on the renal arteries of patients treated with balloon-based and nonballoon-based denervation systems by quantitative angiography, intravascular ultrasound, and optical coherence tomography (OCT). Methods and Results Twenty-five patients (50 ...

    6. A novel method to assess coronary artery bifurcations by OCT: cut-plane analysis for side-branch ostial assessment from a main-vessel pullback

      A novel method to assess coronary artery bifurcations by OCT: cut-plane analysis for side-branch ostial assessment from a main-vessel pullback
      Aims In coronary bifurcations assessment, evaluation of side-branch (SB) ostia by an optical coherence tomography (OCT) pullback performed in the main branch (MB) could speed up lesion evaluation and minimize contrast volume. Dedicated software that reconstructs the cross-sections perpendicular to the SB centreline could improve this assessment. We aimed to validate a new method for assessing the SB ostium from an OCT pullback performed in the MB. Methods and results ...

    7. The impact of Fourier-Domain optical coherence tomography catheter induced motion artefacts on quantitative measurements of a PLLA-based bioresorbable scaffold

      The impact of Fourier-Domain optical coherence tomography catheter induced motion artefacts on quantitative measurements of a PLLA-based bioresorbable scaffold
      Intracoronary Fourier-Domain optical coherence tomography (FD-OCT) enables imaging of the coronary artery within 2-4 seconds, a so far unparalleled speed. Despite such fast data acquisition, cardiac and respiratory motion can cause artefacts due to longitudinal displacement of the catheter within the artery. We studied the influence of longitudinal FD-OCT catheter displacement on serial global lumen and scaffold area measurements in coronary arteries of swine that received PLLA-based bioresorbable scaffolds. In ...

    8. Optical coherence tomography for evaluation of coronary stents in vivo

      Optical coherence tomography for evaluation of coronary stents in vivo
      Coronary optical coherence tomography (OCT) is a light-based imaging modality that emits light in the near-infrared range. Compared with intravascular ultrasound, OCT has an extraordinarily high resolution (nearly tenfold higher), with an axial resolution in the range of 1215 m and a lateral resolution of 2040 m. The main drawback of OCT is its relatively low penetration power, especially into lipid-rich atherosclerotic tissue. Second-generation OCT systems, known as frequency domain ...
