    1. Frequency-Domain Optical Coherence Tomography for Intracranial Atherosclerotic Stenosis: Feasibility, Safety, and Preliminary Experience

      Frequency-Domain Optical Coherence Tomography for Intracranial Atherosclerotic Stenosis: Feasibility, Safety, and Preliminary Experience
      Background: Despite advances in non-invasive imaging, the characterization of atherosclerotic plaque remains superior with frequency-domain optical coherence tomography (FD-OCT) in the clinical coronary and experimental cerebrovascular literature. An assessment of the feasibility and safety of FD-OCT for intracranial atherosclerotic stenosis (ICAS) is desirable. Methods: We analyzed a cohort of all consecutive FD-OCT evaluations for ICAS performed at our institution from April 2017 to August 2018 (16 months) in patients who ...

    2. EROSION Study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence Tomography–Based Management in Plaque Erosion)

      EROSION Study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence Tomography–Based Management in Plaque Erosion)
      Background The initial EROSION study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence TomographyBased Management in Plaque Erosion) demonstrated that patients with acute coronary syndrome caused by plaque erosion might be stabilized with aspirin and ticagrelor without stenting for 1 month. However, a long-term evaluation of outcomes is lacking. The aim of this study was to assess whether the initial benefit of noninterventional therapy for patients with acute coronary syndrome ...

    3. Chronic kidney disease predicts coronary plaque vulnerability: an optical coherence tomography study

      Chronic kidney disease predicts coronary plaque vulnerability: an optical coherence tomography study
      Objective: The addition of cystatin C to creatinine in calculating the estimated glomerular filtration rate (eGFR) is known to improve the risk prediction for cardiovascular events. We sought to investigate the associations between eGFRs calculated by three Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations and coronary plaque phenotype by optical coherence tomography. Patients and methods: We analyzed 181 nonculprit plaques from 116 coronary artery disease patients. For each patient, the ...

    4. Comparison by Optical Coherence Tomography of the Frequency of Lipid Coronary Plaques in Current Smokers, Former Smokers, and Non-smokers

      Comparison by Optical Coherence Tomography of the Frequency of Lipid Coronary Plaques in Current Smokers, Former Smokers, and Non-smokers
      Smoking is associated with high incidence of cardiovascular events including acute coronary syndrome (ACS). We sought to characterize coronary plaques in patients with ongoing smoking using optical coherence tomography (OCT) compared to former smokers and nonsmokers. We identified 465 coronary plaques from 182 subjects who underwent OCT imaging for all three coronary arteries. Subjects were divided into 3 groups: current smokers (n=41), former smokers (n=67) and nonsmokers (n ...

      State of the Industry report on Optical Coherence Tomography
      The first commercial optical coherence tomography (OCT) imagers were introduced to ophthalmology by Advanced Ophthalmic Devices (now owned by Zeiss Meditec) in 1992. Since then, the market for OCT systems has grown at an impressive compounded annual rate of about 45%. This segment of the biophotonics marketplace has flourished because OCT enables sub-surface imaging of translucent or opaque materials, such as human tissue, in real time at micron resolution and ...

    7. Pancoronary Plaque Vulnerability in Patients with Acute Coronary Syndrome and Ruptured Culprit Plaque: A Three-Vessel Optical Coherence Tomography Study

      Pancoronary Plaque Vulnerability in Patients with Acute Coronary Syndrome and Ruptured Culprit Plaque: A Three-Vessel Optical Coherence Tomography Study
      Background Recent studies described different clinical and underlying plaque characteristics between patients with and without plaque rupture presenting with acute coronary syndrome (ACS). In light of the systemic nature of atherosclerosis, we hypothesized that non-culprit plaques might also express different morphological features in these two groups of patients. Methods Thirty-eight patients with ACS who underwent 3-vessel optical coherence tomography (OCT) imaging were identified from the Massachusetts General Hospital OCT Registry ...

      In Vivo Diagnosis of Plaque Erosion and Calcified Nodule in Patients with Acute Coronary Syndrome by Intravascular Optical Coherence Tomography
      Objectives To characterize the morphological features of plaque erosion and calcified nodule in patients with acute coronary syndrome (ACS) by optical coherence tomography (OCT). Background Plaque erosion and calcified nodule have not been systematically investigated in vivo . Methods One hundred and twenty-six patients with ACS who had undergone pre-intervention OCT imaging were included. The culprit lesions were classified as plaque rupture (PR), erosion (OCT-erosion), calcified nodule (OCT-CN), or others using ...

    13. Comparison of Tissue Architectural Changes between Radiofrequency Ablation and Cryospray Ablation in Barrett’s Esophagus Using Endoscopic Three-Dimensional Optical Coherence Tomography

      Comparison of Tissue Architectural Changes between Radiofrequency Ablation and Cryospray Ablation in Barrett’s Esophagus Using Endoscopic Three-Dimensional Optical Coherence Tomography
      Two main nonsurgical endoscopic approaches for ablating dysplastic and early cancer lesions in the esophagus have gained popularity, namely, radiofrequency ablation (RFA) and cryospray ablation (CSA). We report a uniquely suited endoscopic and near-microscopic imaging modality, three-dimensional (3D) optical coherence tomography (OCT), to assess and compare the esophagus immediately after RFA and CSA. The maximum depths of architectural changes were measured and compared between the two treatment groups. RFA was ...
