    2. Impact on Optical Coherence Tomographic Coronary Findings of Fluvastatin Alone versus Fluvastatin+ Ezetimibe

      Impact on Optical Coherence Tomographic Coronary Findings of Fluvastatin Alone versus Fluvastatin+ Ezetimibe
      Although lipid lowering therapy by statin and ezetimibe has been reported to provide greater reduction in low-density lipoprotein cholesterol (LDL-C) levels than statin monotherapy, the effect of supplemental therapy on plaque stabilization is yet to be fully elucidated. Cap thickness of fibroatheroma evaluated by Optical coherence tomography (OCT) is a major determinant of vulnerable plaque. The primary objective of this study is to evaluate the effect of ezetimibe in addition ...

    4. Morphological differences of tissue characteristics between early, late, and very late restenosis lesions after first generation drug-eluting stent implantation: an optical coherence tomography study

      Morphological differences of tissue characteristics between early, late, and very late restenosis lesions after first generation drug-eluting stent implantation: an optical coherence tomography study
      Aims Restenosis of drug-eluting stents (DESs) might be different from that of bare metal stent restenosis in diverse ways including mechanisms and time course; however, these have not been fully examined. To gain insight into the mechanisms and time course of DES restenosis, we evaluated the characteristics of restenotic lesions of first generation DES using optical coherence tomography (OCT). Methods and results We compared the morphological characteristics of early in-stent ...

    6. Impact of Frequency-Domain Optical Coherence Tomography Guidance for Optimal Coronary Stent Implantation in Comparison With Intravascular Ultrasound Guidance

      Impact of Frequency-Domain Optical Coherence Tomography Guidance for Optimal Coronary Stent Implantation in Comparison With Intravascular Ultrasound Guidance
      Background—Frequency-domain optical coherence tomography (FD-OCT) is a novel, high resolution intravascular imaging modality. Intravascular ultrasound (IVUS) is a widely used conventional imaging modality for achieving optimal stent deployment. The aim of this study was to evaluate the impact of FD-OCT guidance for coronary stent implantation compared with IVUS guidance. Methods and Results—A total of 70 patients with de novo coronary artery lesions and either unstable or stable angina ...

    7. Association of coronary plaque composition and arterial remodelling: A optical coherence tomography study - Corrected Proof

      Association of coronary plaque composition and arterial remodelling: A optical coherence tomography study - Corrected Proof
      Background Conflicting data have been reported about the association between plaque composition and remodelling index (RI). The aim of this study is to evaluate the relationship between plaque morphology obtained by optical coherence tomography (OCT) and arterial remodelling. Methods and results OCT and intravascular ultrasound imaging pull back was performed at corresponding sites on 94 lesions in 47 patients. OCT plaque characteristics for lipid content, fibrous cap thickness, thin-cap fibroatheroma ...

    8. The impact of epicardial fat volume on coronary plaque vulnerability: insight from optical coherence tomography analysis

      The impact of epicardial fat volume on coronary plaque vulnerability: insight from optical coherence tomography analysis
      Aims Epicardial fat volume (EFV) has been implicated in coronary artery disease. Relationship between EFV and coronary plaque vulnerability has not been elucidated. The aim of this study was to investigate the association of EFV with coronary plaque vulnerability by using optical coherence tomography (OCT). Methods and results We enrolled 117 patients who underwent multislice computed tomography (MSCT) and OCT. EFV was quantified on MSCT. Patients were categorized according to ...

    9. Difference of Tissue Characteristics Between Early and Very Late Restenosis Lesions After Bare-Metal Stent Implantation: An Optical Coherence Tomography Study

      Difference of Tissue Characteristics Between Early and Very Late Restenosis Lesions After Bare-Metal Stent Implantation: An Optical Coherence Tomography Study
      Background—Although in-stent restenosis (ISR) after bare-metal stent (BMS) implantation peaks in the early phase, very late (VL) ISR occasionally is observed beyond a few years after BMS implantation. To date, this mechanism has not been fully clarified. Methods and Results—We compared the morphological characteristics of VL-ISR (>5 years, without restenosis within the first year) (n=43) to those of early (E) ISR (within the first year) (n=39 ...

    10. Comparison of In Vivo Assessment of Vulnerable Plaque by 64-Slice Multislice Computed Tomography Versus Optical Coherence Tomography

      Comparison of In Vivo Assessment of Vulnerable Plaque by 64-Slice Multislice Computed Tomography Versus Optical Coherence Tomography
      The aim of this study was to investigate the possibility of 64-slice multislice computed tomography (MSCT) to detect vulnerable plaque derived by optical coherence tomography. From September 2007 through December 2009, 122 lesions in 81 patients were evaluated by 64-slice MSCT and optical coherence tomography. Based on optical coherence tomographic findings, lesions were classified as thin-capped fibroatheroma (TCFA; n = 37) and non-TCFA (n = 85). Mean computed tomographic density value of ...

      In-vivo detection of the frequency and distribution of thin-cap fibroatheroma and ruptured plaques in patients with coronary artery disease: an optical coherence tomographic study
      Objectives: The purpose of this study was to assess the prevalence and to quantify the thin-cap fibroatheroma (TCFA) and ruptured plaques in patients with coronary artery disease using optical coherence tomography (OCT). Background: TCFA lesions are the most prevalent precursors of plaque rupture, and are responsible for acute coronary syndromes (ACS). There are limited data regarding the frequency and distribution of TCFA in diseased coronary arteries. Methods: Coronary artery OCT ...
