    2. Impact of Eicosapentaenoic Acid Treatment on the Fibrous Cap Thickness in Patients with Coronary Atherosclerotic Plaque: An Optical Coherence Tomography Study

      Impact of Eicosapentaenoic Acid Treatment on the Fibrous Cap Thickness in Patients with Coronary Atherosclerotic Plaque: An Optical Coherence Tomography Study

      Aim : Previous clinical trials have demonstrated the effectiveness of eicosapentaenoic acid (EPA) in preventing cardiovascular events. The aim of the present study was to investigate the effects of EPA treatment on the accumulation of coronary atherosclerotic plaque using optical coherence tomography (OCT). Methods : A total of 46 acute coronary syndrome (ACS) patients without dyslipidemia were divided into two groups: those who received 1,800 mg/day of EPA ( n =15) or the control group ( n =31). Serial OCT examinations were performed at baseline and after eight months of follow-up. The target for the OCT analysis was non-culprit plaque with a ...

    4. Evaluation of coronary arterial lesions due to Kawasaki disease using optical coherence tomography

      Evaluation of coronary arterial lesions due to Kawasaki disease using optical coherence tomography

      Optical coherence tomography (OCT) is a high-resolution intracoronary arterial imaging modality. We describe two patients who were admitted to undergo coronary angiography (CAG) and OCT for follow-up of Kawasaki disease (KD) with coronary artery aneurysms. OCT clearly demonstrated thrombus, stenosis, fibrotic intimal thickening with lamellar calcification and partial disappearance of the tunica media at the aneurysm site. In addition, focal calcification, intimal thickening and medial irregularity were observed even in regions of coronary arterial walls that appeared to be normal by CAG. OCT is useful for evaluating coronary arterial sequelae of KD.

    5. Association between P-selectin Glycoprotein Ligand-1 and Pathogenesis in Acute Coronary Syndrome Assessed by Optical Coherence Tomography

      Association between P-selectin Glycoprotein Ligand-1 and Pathogenesis in Acute Coronary Syndrome Assessed by Optical Coherence Tomography

      Objective Although monocytes appear to be actively involved in the onset of acute coronary syndrome (ACS), they are heterogenous in human peripheral blood. How up-regulation of monocyte subsets leads to coronary plaque rupture followed by thrombus formation remains unclear. Recent studies have shown that P-selectin glycoprotein ligand-1 (PSGL-1) is involved in monocyte activation in patients with thrombus formation. We therefore investigated the relationship between the expression of PSGL-1 on monocyte subsets and thrombus formation using frequency-domain optical coherence tomography (FD-OCT) in patients with ACS. Methods We enrolled a total of 100 individuals in this study: patients with acute myocardial infarction ...

    9. Monolithically grown multi-color InAs quantum dots as a spectral-shape-controllable near-infrared broadband light source

      Monolithically grown multi-color InAs quantum dots as a spectral-shape-controllable near-infrared broadband light source

      We have grown monolithic multi-color InAs quantum dots (QDs) for use as a near-infrared (NIR) broadband light source. Our previously developed rotational metal mask enables selective-area growth of QD ensembles with emission peak wavelengths controlled by strain-reducing layers thicknesses, varying the emission approximately 1.2–1.3  μ m. The peak shift value was up to 120 nm, and a combined 160-nm-bandwidth emission spectrum was achieved. Further, the emission spectra shapes were controlled using specific optical excitation powers for each QD ensemble. These results demonstrate the effectiveness of multi-color QDs as a spectrum-shape-controllable NIR broadband light source, particularly suited for optical ...

    10. Inter-Scan Reproducibility of Geometric Coronary Artery Measurements Using Frequency-Domain Optical Coherence Tomography

      Inter-Scan Reproducibility of Geometric Coronary Artery Measurements Using Frequency-Domain Optical Coherence Tomography

      Frequency-domain optical coherence tomography (FD-OCT) is a novel technology which provides high-resolution cross-sectional images of coronary arteries. The aim of this study was to evaluate the inter-scan reproducibility of geometric FD-OCT measurements in the clinical setting. We examined 20 coronary lesions using FD-OCT. Following the FD-OCT image acquisition (1 st pullback), and after the disengagement and re-engagement of the guiding catheter, an additional acquisition (2 nd pullback) was performed using a new FD-OCT catheter. There was excellent correlation for minimum lumen area ( r = 0.99, P < 0.001), lesion length ( r = 0.99, P < 0.001) and lumen volume ( r ...
