    2. Accuracy of OCT, Grayscale IVUS, and Their Combination for the Diagnosis of Coronary TCFA An Ex Vivo Validation Study

      Accuracy of OCT, Grayscale IVUS, and Their Combination for the Diagnosis of Coronary TCFA An Ex Vivo Validation Study
      Objectives This study sought to assess the accuracy of optical coherence tomography (OCT), gray-scale intravascular ultrasound (IVUS), and their combination for detecting thin-cap fibroatheromas (TCFA). Background The extent to which the imaging characteristics of OCT and IVUS correlate with histologically defined TCFA is unknown. Methods IVUS and OCT examinations identified focal plaques in 165 coronary arteries from 60 autopsy hearts. A total of 685 pairs of images of OCT and ...

    3. Natural history of low-intensity neointimal tissue after an everolimus-eluting stent implantation: a serial observation with optical coherence tomography

      Natural history of low-intensity neointimal tissue after an everolimus-eluting stent implantation: a serial observation with optical coherence tomography
      Although previous optical coherence tomography (OCT) studies reported that restenosis tissue after implantation of a drug-eluting stent (DES) was composed of a variety of cells, the clinical significance of morphologic characteristics for in-stent neointimal tissue as assessed by OCT has not been clarified. We experienced a patient with stable angina who underwent percutaneous coronary intervention with a 2.5 18-mm DES implantation 6 months before the OCT examination. OCT imaging ...

    4. Multiple complex coronary atherosclerosis in diabetic patients with acute myocardial infarction: a three-vessel optical coherence tomography study

      Multiple complex coronary atherosclerosis in diabetic patients with acute myocardial infarction: a three-vessel optical coherence tomography study
      Aims: The main cause of acute myocardial infarction (AMI) is the disruption of a thin-cap fibroatheroma (TCFA) and subsequent thrombosis. Mortality increases in diabetic patients due to cardiovascular events; there may be differences in the vulnerable plaques between diabetic and non-diabetic patients. We used optical coherence tomography (OCT) to assess the incidence of vulnerable plaques in diabetic patients with AMI. Methods and results: OCT was performed in all three major ...

    5. Endothelium-dependent coronary vasomotor response and neointimal coverage of zotarolimus-eluting stents 3 months after implantation

      Endothelium-dependent coronary vasomotor response and neointimal coverage of zotarolimus-eluting stents 3 months after implantation
      Background Zotarolimus-eluting stents (ZES) have a higher rate of neointimal coverage than the first-generation drug-eluting stents on optical coherence tomography (OCT). Objective To determine whether neointimal coverage of stent struts detected by OCT can be used as a surrogate for endothelial function after ZES implantation. Design Cross-sectional observational study. Setting Three months after ZES implantation. Patients and methods OCT was performed in 20 patients with a ZES at 3 months ...

    7. Frequency and Predictor of Coronary Thin-Cap Fibroatheroma in Patients With Acute Myocardial Infarction and Stable Angina Pectoris: A 3-Vessel Optical Coherence Tomography Study

      Frequency and Predictor of Coronary Thin-Cap Fibroatheroma in Patients With Acute Myocardial Infarction and Stable Angina Pectoris: A 3-Vessel Optical Coherence Tomography Study
      (A) A 90% stenosis observed in the middle left anterior descending artery in patients with stable angina pectoris (arrow). (B) Lipid-rich plaque (L) covered by thin fibrous cap (63.3 m) (arrowheads) observed in the target lesion of a patient with stable angina pectoris. (C) Lipid-rich plaque (L) covered by thin fibrous cap (arrowheads) detected in the noninfarct-related lesion of an acute myocardial infarction patient. (D) Magnification of (C). The ...
