    2. Coronary optical coherence tomography: A practical overview of current clinical applications

      Coronary optical coherence tomography: A practical overview of current clinical applications
      Coronary optical coherence tomography has emerged as the most powerful in-vivo imaging modality to evaluate vessel structure in detail. It is a useful research tool that provides insights into the pathogenesis of coronary artery disease. This technology has an important clinical role that is still being developed. We review the evidence on the wide spectrum of potential clinical applications for coronary optical coherence tomography, which encompass the successive stages in ...

    3. Comparative analysis method of permanent metallic stents (XIENCE) and bioresorbable poly-L-lactic (PLLA) scaffolds (Absorb) on optical coherence tomography at baseline and follow-up

      Comparative analysis method of permanent metallic stents (XIENCE) and bioresorbable poly-L-lactic (PLLA) scaffolds (Absorb) on optical coherence tomography at baseline and follow-up
      Aims: Fully bioresorbable Absorb poly-L-lactic-acid (PLLA) scaffolds (Abbott Vascular, Santa Clara, CA, USA) are a novel approach for the treatment of coronary narrowing. Due to the translucency of the material (PLLA), the optical coherence tomography (OCT) measurement methods used in the ABSORB trials were unique but not applicable for permanent metallic stents. When the Absorb scaffold and metallic stents are compared in the context of randomised trials, it is challenging ...

    4. 3-D Stent Detection in Intravascular OCT Using a Bayesian Network and Graph Search

      3-D Stent Detection in Intravascular OCT Using a Bayesian Network and Graph Search
      Worldwide, many hundreds of thousands of stents are implanted each year to revascularize occlusions in coronary arteries. Intravascular optical coherence tomography (OCT) is an important emerging imaging technique, which has the resolution and contrast necessary to quantitatively analyze stent deployment and tissue coverage following stent implantation. Automation is needed, as current, it takes up to 16 hours to manually analyze hundreds of images and thousands of stent struts from a ...

    5. Parameter estimation of atherosclerotic tissue optical properties from three-dimensional intravascular optical coherence tomography

      Parameter estimation of atherosclerotic tissue optical properties from three-dimensional intravascular optical coherence tomography
      We developed robust, three-dimensional methods, as opposed to traditional A-line analysis, for estimating the optical properties of calcified, fibrotic, and lipid atherosclerotic plaques from in vivo coronary artery intravascular optical coherence tomography clinical pullbacks. We estimated attenuation t and backscattered intensity I 0 from small volumes of interest annotated by experts in 35 pullbacks. Some results were as follows: noise reduction filtering was desirable, parallel line (PL) methods outperformed individual ...

      Mechanisms of Atherothrombosis and Vascular Response to Primary Percutaneous Coronary Intervention in Women Versus Men With Acute Myocardial Infarction : Results of the OCTAVIA (Optical Coherence Tomography Assessment of Gender Diversity in Primary Angiop
      Objectives This study sought to assess in vivo sex differences in the pathophysiology of ST-segment elevation myocardial infarction (STEMI) and vascular response to primary percutaneous coronary intervention (PCI). Background There is no consensus on whether differences in the pathophysiology of STEMI and response to primary PCI between women and men reflect biological factors as opposed to differences in age. Methods In this prospective, multicenter study, 140 age-matched men and women ...

    8. Impact of Main-Branch Calcified Plaque on Side-Branch Stenosis in Bifurcation Stenting: An Optical Coherence Tomography Study

      Impact of Main-Branch Calcified Plaque on Side-Branch Stenosis in Bifurcation Stenting: An Optical Coherence Tomography Study
      Percutaneous coronary intervention (PCI) in bifurcations is routinely performed, however this procedure is associated with higher rates of adverse events compared non-bifurcation PCI [1,2]. While bifurcation PCI per se leads to progressively higher rates of periprocedural myocardial infarction as its complexity increases (i.e., 1- vs. 2-stent technique) [3], side-branch (SB) stenosis (SBS) after main-branch (MB) stenting may further contribute to myocardial ischemia and necrosis; in addition, it might ...

    9. Intravascular Frequency-Domain Optical Coherence Tomography Assessment of Carotid Artery Disease in Symptomatic and Asymptomatic Patients

      Intravascular Frequency-Domain Optical Coherence Tomography Assessment of Carotid Artery Disease in Symptomatic and Asymptomatic Patients
      Objectives The goal of this study was to investigate carotid plaque characteristics in symptomatic versus asymptomatic patients with the use of nonocclusive optical coherence tomography (OCT). Background The identification of asymptomatic patients with carotid disease who are at risk of stroke remains a challenge. There is an increasing awareness that plaque characteristics may best risk-stratify this population. We hypothesized that OCT, a new high-resolution (10 m) imaging modality, might be ...

      Segmentation and quantification for intravascular optical coherence tomography images
      A system and related methods for automatic or semi-automatic segmentation and quantification of blood vessel structure and physiology, including segmentation and quantification of lumen, guide wire, vessel wall, calcified plaques, fibrous caps, macrophages, metallic and bioresorbable stents are described, and including visualization of results. Calcified plaque segmentation can be used to estimate the distribution of superficial calcification and inform strategies stenting. Volumetric segmentation and quantification of fibrous caps can provide ...

      Optical coherence tomography of the intracranial vasculature and Wingspan stent in a patient
      A 67-year-old man with medically refractory vertebrobasilar insufficiency and short segment occlusions of the intracranial vertebral arteries was treated with angioplasty and stent placement. Fifteen hours after the procedure the patient developed symptoms of posterior fossa ischemia and repeat angiography showed thrombus formation within the stent which was treated with thrombolytic and aggressive antiplatelet therapy. Angiography revealed lysis of the clot, but concerns regarding the mechanism of the thrombotic phenomenon ...

      Comprehensive overview of definitions for optical coherence tomography-based plaque and stent analyses
      Optical coherence tomography (OCT) is the current state-of-the-art intracoronary imaging modality that allows visualization of detailed morphological characteristics of both atherosclerotic plaque and stent. So far, three expert review documents have been released for standardization of OCT image analysis. In the real world, a variety of definitions are being used by different groups and by different core laboratories to analyze OCT findings because of different clinical/procedural contexts in which ...

      Frequency-Domain Optical Coherence Tomography Assessment of Unfavorable Kissing-Balloon Result in Unprotected Left Main Intervention
      A 67-year-old man with a history of hypertension and dyslipidemia was admitted because of angina symptoms. Coronary angiography (CAG) showed an eccentric lesion of the distal unprotected left main coronary artery (ULMCA) involving the ostium of the left anterior descending coronary artery (LAD) (Figure 1 A). ULMCA/LAD crossover stent implantation was conducted with a 3.5 18-mm everolimus-eluting stent (EES) (XIENCE PRIME, Abbott Vascular, Santa Clara, California) at 12 ...
