      En-face optical coherence tomography/fluorescence endomicroscopy for minimally invasive imaging using a robotic scanner
      We report a compact rigid instrument capable of delivering en-face optical coherence tomography (OCT) images alongside (epi)-fluorescence endomicroscopy (FEM) images by means of a robotic scanning device. Two working imaging channels are included: one for a one-dimensional scanning, forward-viewing OCT probe and another for a fiber bundle used for the FEM system. The robotic scanning system provides the second axis of scanning for the OCT channel while allowing the ...

      Clinical use of intracoronary imaging. Part 2: acute coronary syndromes, ambiguous coronary angiography findings, and guiding interventional decision-making: an expert consensus document of the European Association of Percutaneous Cardiovascular Intervent
      This consensus document is the second of two reports summarizing the views of an expert panel organized by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) on the clinical use of intracoronary imaging including intravascular ultrasound (IVUS), optical coherence tomography (OCT), and near infrared spectroscopy (NIRS)-IVUS. Beyond guidance of stent selection and optimization of deployment, invasive imaging facilitates angiographic interpretation and may guide treatment in acute coronary syndrome. Intravascular ...

      Compressed sensing-enabled phase-sensitive swept-source optical coherence tomograph
      Here we present a novel phase-sensitive swept-source optical coherence tomography (PhS-SS-OCT) system. The simultaneously recorded calibration signal, which is commonly used in SS-OCT to stabilize the phase, is randomly sub-sampled during the acquisition, and it is later reconstructed based on the Compressed Sensing (CS) theory. We first mathematically investigated the method, and verified it through computer simulations. We then conducted a vibrational frequency test and a flow velocity measurement in ...

      Integrating Handcrafted and Deep Features for Optical Coherence Tomography Based Retinal Disease Classification
      Deep Neural Networks (DNNs) have been widely applied to automatic analysis of medical images for disease diagnosis, and to help human experts by efficiently processing immense amounts of images. While handcrafted feature has been used for eye disease detection or classification since the 1990s, DNN was recently adopted in this area and showed very promising performance. Since handcrafted and deep feature can extract complementary information, we propose in this paper ...

      Changes in Coronary Plaque Composition in Patients With Acute Myocardial Infarction Treated With High-Intensity Statin Therapy (IBIS-4): A Serial Optical Coherence Tomography Study
      Objectives This study assessed changes in optical coherence tomography (OCT)-defined plaque composition in patients with ST-elevation myocardial infarction (STEMI) receiving high-intensity statin treatment. Background OCT is a high-resolution modality capable of measuring plaque characteristics including fibrous cap thickness (FCT) and macrophage infiltration. There is limited in vivo evidence regarding the effects of statins on OCT-defined coronary atheroma composition and no evidence in the context of STEMI. Methods In the ...

      CLARITY Imaging Study
      OCT image quality is necessary to provide accurate diagnostic information to ophthalmologists. The increasing resolution of imaging techniques will require ever more high standards of optical transmission through the cornea and tear film. Given that lubricant drops can improve optical transmission through the cornea, this study will attempt to quantify this. The primary objective is to assess the effect of cross-linked sodium hyaluronate on OCT image quality compared to the ...

      Feature Of The Week 08/01/2018: OCT Shows Promise in Effecting Outcomes after Coronary Intervention Being Associated with Improved Long-Term Survival
      Objectives This study aimed to determine the effect on long-term survival of using optical coherence tomography (OCT) during percutaneous coronary intervention (PCI). Background Angiographic guidance for PCI has substantial limitations. The superior spatial resolution of OCT could translate into meaningful clinical benefits, although limited data exist to date about their effect on clinical endpoints. Methods This was a cohort study based on the Pan-London (United Kingdom) PCI registry, which includes ...

      Plaque Burden Influences Accurate Classification of Fibrous Cap Atheroma by In-Vivo Optical Coherence Tomography in a Porcine Model of Advanced Coronary Atherosclerosis
      Aims: In-vivo validation of coronary optical coherence tomography (OCT) against histology and the effects of plaque burden (PB) on plaque classification remain unreported. We investigated this in a porcine model with human-like coronary atherosclerosis. Methods and results: Five female Yucatan D374Y-PCSK9 transgenic hypercholesterolemic mini-pigs were implanted with a coronary shear-modifying stent to induce advanced atherosclerosis. OCT frames (n=201) were obtained 34 weeks after implantation. Coronary arteries were perfusion-fixed, serially ...

      Quality difference of neointima following the implantation of bioresorbable scaffold and metallic stent in patients with ST elevation myocardial infarction: quantitative assessments by light intensity, light attenuation, and backscatter on optical coheren
      Aims: We aimed to assess possible difference of the neointimal quality after everolimus-eluting bioresorbable scaffold (BVS) implantation in comparison with cobalt chromium everolimus-eluting scaffold (CoCr-EES) by optical frequency domain imaging (OFDI). Methods and results: This study is a post-hoc analysis of TROFI II trial assessing neointimal quality 6-month after the implantation of BVS(N=82) and CoCr-EES(N=87) in STEMI patients.

      The role of intracoronary imaging in acute coronary syndromes: OCT in focus
      Optical coherence tomography (OCT) has emerged as a powerful intravascular imaging modality in recent years. The introduction of frequency-domain OCT has simplified the procedure and enabled its safe utilisation in different clinical settings including acute coronary syndromes, where it can determine the mechanism of plaque disruption, thrombus burden, and guide percutaneous coronary intervention. In patients presenting with stent failure (stent thrombosis and instent restenosis), OCT can also be very useful ...
