    2. In vivo tissue characterization of human atherosclerotic plaques by optical coherence tomography: A directional coronary atherectomy study with histopathologic confirmation

      In vivo tissue characterization of human atherosclerotic plaques by optical coherence tomography: A directional coronary atherectomy study with histopathologic confirmation
      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. Angiographical Changes Induced by Tiny Coronary Fistula

      Angiographical Changes Induced by Tiny Coronary Fistula
      An 82-year-old female presented with angina pectoris due to mid-right coronary artery (RCA) stenosis. Percutaneous coronary intervention (PCI) was performed with optical coherence tomography (OCT). When OCT was performed with manual coronary flushing to obtain a clearer image, the contrast media seemed to extravasate from the coronary artery, resembling a coronary perforation; however, the patient did not have any chest pain and her vital signs were stable. Coronary angiography (CAG ...

    4. 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 ...

      Feature Of The Week 6/5/11: Researchers from Toyohashi Heart Center Compare Multislice Computed Tomography and Optical Coherence Tomography for In-Vivo Assessment of Vulnerable Plaque
      Cardiovascular disease is one of the major causes of death in the world. One component of this deadly disease is the rupture or thin walled unstable plaques. Increased detection of rupture-prone vulnerable plaque could be promising for better risk stratification of patients. Intravascular OCT has emerged as one of the most promising techniques for non-ionizing, high-resolution, in-vivo plaque characterization and assessment. However OCT is still an (minimally) invasive procedure. Multislice ...

    6. 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 ...
