    2. Towards a better understanding of the posttreatment hemodynamic behaviors in femoropopliteal arteries through personalized computational models based on OCT images

      Towards a better understanding of the posttreatment hemodynamic behaviors in femoropopliteal arteries through personalized computational models based on OCT images
      The hemodynamic behavior following endovascular treatment of patients with peripheral arterial disease plays a significant role on the occurrence of restenosis in femoro-popliteal (FP) arteries. The atheroprone flow conditions that are generally accepted to promote restenosis can be calculated by computational fluid dynamics (CFD) analyses, and these results can be used to assess individualized treatment outcomes. However, the impact of endovascular therapy on the flow behaviors of FP arteries are ...

    3. Coronary embolism due to possible thrombosis of prosthetic aortic valve - the role of optical coherence tomography: case report

      Coronary embolism due to possible thrombosis of prosthetic aortic valve - the role of optical coherence tomography: case report
      Background: Coronary embolism is an important non-atherosclerotic cause of acute myocardial infarction (AMI) that requires an individualized diagnostic and therapeutic approach. Although certain angiographic criteria exist that render an embolic origin likely, uncertainty remains. Optical coherence tomography (OCT) is a high-resolution intracoronary imaging technology that enables visualization of thrombus and the underlying coronary vessel wall, which may be helpful to distinguish between an atherosclerotic and non-atherosclerotic origin of AMI. Case ...

    4. Impact of intracoronary optical coherence tomography in routine clinical practice: A contemporary cohort study

      Impact of intracoronary optical coherence tomography in routine clinical practice: A contemporary cohort study
      Background/purpose: Guidelines recommend intracoronary optical coherence tomography (OCT) to assess stent failure and guide percutaneous coronary intervention (PCI) but OCT may be useful for other indications in routine clinical practice. Methods/materials: We conducted an international registry of OCT cases at two large tertiary care centers to assess clinical indications and the potential impact on decision making of OCT in clinical routine. Clinical indications, OCT findings, and their impact ...

    5. Evaluating the Safety of the Spectralis Centaurus Device

      Evaluating the Safety of the Spectralis Centaurus Device
      Optical microsurgery of the retinal pigment epithelium (RPE) requires reliable real-time dosimetry to prevent unwanted overexposure of the neuroretina. The SPECTRALIS CENTAURUS device implements optical coherence tomography (OCT) to detect intentional elimination of RPE cells caused by a prototype laser for selective retina therapy (SRT). Within this clinical trial the safety of the SPECTRALIS CENTAURUS device and its ability to detect RPE cell damage towards selective real-time laser microsurgery will ...

    6. Discordance in the diagnostic assessment of vulnerable plaques between radiofrequency intravascular ultrasound versus optical coherence tomography among patients with acute myocardial infarction: insights from the IBIS-4 study

      Discordance in the diagnostic assessment of vulnerable plaques between radiofrequency intravascular ultrasound versus optical coherence tomography among patients with acute myocardial infarction: insights from the IBIS-4 study
      We aimed to evaluate the diagnostic agreement between radiofrequency (RF) intravascular ultrasound (IVUS) and optical coherence tomography (OCT) for thin-cap fibroatheroma (TCFA) in non-infarct-related coronary arteries (non-IRA) in patients with ST-segment elevation myocardial infarction (STEMI). In the Integrated Biomarker Imaging Study (IBIS-4), 103 STEMI patients underwent OCT and RF-IVUS imaging of non-IRA after successful primary percutaneous coronary intervention and at 13-month follow-up. A coronary lesion was defined as a segment ...

      Optical Coherence Tomography Findings After Atherectomy Devices | Icr Journal
      Heavily calcified coronary artery lesions hinder the delivery of devices and limit stent expansion, resulting in low procedural success and poor clinical outcomes driven by an increase in restenosis and stent thrombosis. Intracoronary imaging provides a more precise assessment of lesions and is a critical step when deciding whether the lesion needs to be prepared with atherectomy devices. Physiological assessment of lesion significance is an important consideration to avoid unnecessary ...

    8. Effects of the PCSK9 Antibody Alirocumab on Coronary Atherosclerosis in Patients with Acute Myocardial Infarction: A Serial, Multivessel, Intravascular Ultrasound, Near-Infrared Spectroscopy and Optical Coherence Tomography Imaging Study Rationale and Des

      Effects of the PCSK9 Antibody Alirocumab on Coronary Atherosclerosis in Patients with Acute Myocardial Infarction: A Serial, Multivessel, Intravascular Ultrasound, Near-Infrared Spectroscopy and Optical Coherence Tomography Imaging Study Rationale and Des
      Background: The risk for cardiovascular adverse events after acute myocardial infarction (AMI) remains high despite potent medical treatment including low-density lipoprotein cholesterol (LDL-C) lowering with statins. Proprotein convertase subtilisin/kexin type 9 (PCSK9) antibodies substantially reduce LDL-C when added to statin. Alirocumab, a momoclonal antibody to PCSK9, reduces major adverse cardiovascular events after AMI. The effects of alirocumab on coronary atherosclerosis including plaque burden, plaque composition and fibrous cap thickness ...

    9. The APOSTEL 2.0 Recommendations for Reporting Quantitative Optical Coherence Tomography Studies

      The APOSTEL 2.0 Recommendations for Reporting Quantitative Optical Coherence Tomography Studies
      Objective: To update the consensus recommendations for reporting of quantitative optical coherence tomography (OCT) study results, thus revising the previously published Advised Protocol for OCT Study Terminology and Elements (APOSTEL) recommendations. Methods: To identify studies reporting quantitative OCT results, we performed a PubMed search for the terms "quantitative" and "optical coherence tomography" from 2015 to 2017. Corresponding authors of the identified publications were invited to provide feedback on the initial ...

      Assessment of patient specific information in the wild on fundus photography and optical coherence tomography
      In this paper we analyse the performance of machine learning methods in predicting patient information such as age or sex solely from retinal imaging modalities in a heterogeneous clinical population. Our dataset consists of N = 135,667 fundus images and N = 85,536 volumetric OCT scans. Deep learning models were trained to predict the patient's age and sex from fundus images, OCT cross sections and OCT volumes. For sex ...
