    3. Relation of Microchannel Structure Identified by Optical Coherence Tomography to Plaque Vulnerability in Patients With Coronary Artery Disease

      Relation of Microchannel Structure Identified by Optical Coherence Tomography to Plaque Vulnerability in Patients With Coronary Artery Disease
      Increased neovascularization in atherosclerotic plaques is associated with plaque vulnerability. The high resolution of optical coherence tomography (OCT) might provide a chance to directly visualize plaque neovascularization in vivo. The aim of the present study was to investigate the relation between microchannels in culprit plaques identified by OCT and plaque vulnerability in patients with coronary artery disease. A total of 63 consecutive patients with coronary artery disease who had undergone ...

    4. Multiple Coronary Lesion Instability in Patients With Acute Myocardial Infarction as Determined by Optical Coherence Tomography

      Autopsy studies have suggested that acute myocardial infarction (AMI) represents a pan-coronary process of vulnerable plaque development. We performed multifocal optical coherence tomographic (OCT) examination to compare coronary lesion instability between AMI and stable angina pectoris (SAP). A total of 42 patients with AMI (n = 26) or SAP (n = 16) who had multivessel disease and underwent multivessel coronary intervention were enrolled in the present study. The OCT examination was performed ...

    6. Advantage of next-generation frequency-domain optical coherence tomography compared with conventional time-domain system in the assessment of coronary lesion

      Background: Intracoronary optical coherence tomography (OCT) is a high-resolution imaging modality used for evaluation of coronary lesion morphology. However, current time-domain OCT (TD-OCT) have a number of limitations with regard to both procedural usage and safety in the clinical setting. The next-generation frequency-domain OCT (FD-OCT), which has a much faster frame rate and pullback speed than TD-OCT, is expected to overcome these limitations. The aim of this study was to ...

    7. Head to head comparison between the conventional balloon occlusion method and the non-occlusion method for optical coherence tomography

      Abstract: Background: Optical coherence tomography (OCT) has been introduced as a high-resolution imaging modality for the coronary arteries. The current OCT system, however, has a serious limitation in that the image acquisition method requires a soft balloon occlusion to avoid signal scattering from red blood cells.Purpose: The purpose of this study was to compare OCT images from the conventional balloon occlusion method and a non-occlusion image acquisition method, the ...

    8. Relationship Between Coronary Arterial Remodeling, Fibrous Cap Thickness and High-Sensitivity C-Reactive Protein Levels in Patients With Acute Coronary Syndrome

      Thin-capped fibroatheroma (TCFA) is a recognized precursor lesion for acute coronary syndrome (ACS). Positive remodeling (PR) is the predominant pattern of arterial remodeling in patients with ACS. The aim of this study was to evaluate the relationship between coronary arterial remodeling, fibrous cap thickness and high-sensitivity C-reactive protein (hs-CRP) concentration in patients with ACS. Methods and Results: The 47 consecutive ACS patients were enrolled in this study. Arterial remodeling of ...

    9. Intracoronary optical coherence tomography assessment of spontaneous coronary artery dissection

      Optical coherence tomography (OCT; ImageWire, LightLab Imaging, Westford, Massachusetts, USA) is an imaging modality with a high resolution of about 10–20 µm, and can visualise the intima, media and adventitia as well as the histological examination. A 40-year-old woman was admitted with sudden-onset chest pain at rest. She had no collagen tissue disease, no trauma, no Marfan’s syndrome and Ehlers–Danlos syndrome on physical examination and no risk ...

    11. Various Types of Plaque Disruption in Culprit Coronary Artery Visualized by Optical Coherence Tomography in a Patient With Unstable Angina

      A 58-year-old man underwent cardiac catheterization for unstable angina. The coronary angiogram revealed severe stenosis of the right coronary artery. Although 20-MHz, phased-array intravascular ultrasound (IVUS) only visualized eccentric, low echoic plaque at the culprit site, optical coherence tomography (OCT) clearly revealed ruptured plaque and an intraluminal thrombus. OCT also revealed a small ruptured plaque and an eroded plaque with intraluminal thrombi in a distal site remote from the culprit ...
