      Background The histopathological validation of optical coherence tomography (OCT) in visualizing atherosclerotic plaques has been reported only in ex vivo studies. We sought to evaluate the accuracy of OCT in tissue characterization in vivo . Methods and results A total of 25 patients with stable angina pectoris who underwent directional coronary atherectomy (DCA) were included in the investigation, whereby OCT was performed before and after a single debulking. The debulked region ...

    3. In-stent restenosis assessed by frequency-domain optical coherence tomography shows smooth coronary arterial healing process in second-generation drug-eluting stents

      In-stent restenosis assessed by frequency-domain optical coherence tomography shows smooth coronary arterial healing process in second-generation drug-eluting stents
      Introduction: The pathophysiology and mechanism of in-stent restenosis (ISR) after implantation of second-generation drug-eluting stents (DESs) are not fully clear. We compared the morphological characteristics of ISR between first- and second-generation DESs using frequency-domain optical coherence tomography (OCT). Methods: Patients who underwent follow-up coronary angiography (CAG) after first(Cypher and Taxus) and second- (Nobori, Promus Element, Resolute Integrity and Xience) generation DES implantations were examined. ISR was defined as lesions ...

    4. Association of Morphologic Characteristics on Optical Coherence Tomography and Angiographic Progression Patterns of Late Restenosis After Drug-Eluting Stent Implantation

      Association of Morphologic Characteristics on Optical Coherence Tomography and Angiographic Progression Patterns of Late Restenosis After Drug-Eluting Stent Implantation
      Objectives To gain insight into the pathophysiology of late drug-eluting stent (DES) restenosis. Background Restenosis of DES has a different time course from that of bare metal stents. Methods Patients who underwent follow-up coronary angiography (CAG) twice (six to nine months and 18 to 24 months) after DES implantation were examined using optical coherence tomography (OCT). All lesions with target lesion revascularization at first follow-up were excluded. Late catch-up was ...

    5. 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 ...

    7. 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 ...

    9. Serial optical coherence tomography imaging of the “black-hole” phenomenon by intravascular ultrasound following sirolimus-eluting stent implantation

      Serial optical coherence tomography imaging of the “black-hole” phenomenon by intravascular ultrasound following sirolimus-eluting stent implantation
      A 60-year-old man underwent sirolimus-eluting stent (SES) implantatoni.  At two months, intravascular ultrasound (IVUS) images showed homogenous echolucent appearance within the stent, recognized as a"black-hole" phenomeon.  Optical coherence tomography (OCT) images of the correspoinding segment demonstrated a layered structure composed of think inner layers with high-intensity signals and outer layers with low-intensity signals.

      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 ...

    12. The role of optical coherence tomography in coronary intervention

      The role of optical coherence tomography in coronary intervention
      Optical coherence tomography (OCT) is an optical analog of intravascular ultrasound (IVUS) that can be used to examine the coronary arteries and has 10-fold higher resolution than IVUS. Based on polarization properties, OCT can differentiate tissue characteristics (fibrous, calcified, or lipid-rich plaque) and identify thin-cap fibroatheroma. Because of the strong attenuation of light by blood, OCT systems required the removal of blood during OCT examinations. A recently developed frequency-domain OCT ...

      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 ...
