  Purpose : We evaluated the repeatability of wide-field en face swept-source optical coherence tomography angiography (SS-OCTA) in healthy subjects. Methods : Healthy subjects underwent two imaging sessions, on average 8 days apart, with a 100 kHz SS-OCTA instrument. The imaging protocol included a central 3 3 and 12 12 mm scans of the four quadrants resulting in more than a 70 wide-field OCTA of the posterior pole. Quantitative analysis was performed using ...

  Purpose : We investigate which spectral domain-optical coherence tomography (SD-OCT) setting is superior when measuring subfoveal choroidal thickness (CT) and compared results to an automated segmentation software. Methods : Thirty patients underwent enhanced depth imaging (EDI)-OCT. B-scans were extracted in six different settings (W+N = white background/normal contrast 9; W+H = white background/maximum contrast 16; B+N = black background/normal contrast 12; B+H = black background/maximum contrast 16 ...

4. Radiofrequency ablation lesion assessment using optical coherence tomography – a proof‐of‐concept study
  
  Explore Wiley Online Library Mar 23 2019 Cardiology
  
  Background Radiofrequency catheter ablation (RFA) is an effective treatment for atrial fibrillation. However, ablation lesions are usually only assessed functionally. The immediate effect of RFA on the tissue is not directly visualized. Optical coherence tomography (OCT) is an imaging technique that uses light to capture high‐resolution images with histology‐like quality. Therefore, it might be used for high‐precision imaging of ablation lesions. Methods and Results Radiofrequency ablation lesions ...

  Significant left main (LM) stenosis is associated with a poor prognosis, therefore, adequate judgement of the prognostic significance of LM stenosis is essential to improve patients' prognosis. Recently, fractional flow reserve (FFR) has become widespread practice and carries a Class Ia recommendation to assess functional significance of intermediate coronary stenosis in patients with stable angina. Intravascular ultrasound (IVUS)-derived minimum lumen area (MLA) represents an accurate measure to determine LM ...

8. 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
  
  Explore ScienceDirect Dec 19 2018 Cardiology
  
  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 ...

  Purpose To evaluate vascular changes in patients with intermediate uveitis with or without retinal vasculitis using swept-source wide-field optical coherence tomography angiography (OCTA). Methods This is a prospective cross-sectional study. Consecutive patients with intermediate uveitis were evaluated using wide-field OCTA. Wide-field OCTA and en-face OCT images were analysed for the presence of capillary non-perfusion and reduced perfusion, disruption of ellipsoid zone, and abnormalities on en-face wide-field retinal thickness maps, respectively ...

  Purpose To analyze retinal blood flow before and after cataract surgery using swept-source optical coherence tomography angiography (SS-OCTA). Methods Prospective observational study. Consecutive patients were recruited and scanned using SS-OCTA before and after cataract surgery. Laser flare photometry were performed post-surgery. Perfusion and vessel density of superficial (SCP) and deep capillary plexuses (DCP) of the 3 3 mm images as well as foveal avascular zone (FAZ) measurements were assessed. Vessel ...

  Explore Home - ClinicalTrials.gov Jan 17 2018 Ophthalmology , Clinical Trials
  
  Optical coherence tomography angiography (OCTA) is a new non-invasive imaging technique that employs motion contrast imaging to high-resolution volumetric blood flow information. OCTA compares the decorrelation signal between sequential OCT b-scans taken at precisely the same cross-section in order to construct a map of blood flow. At present, level 1 evidence of the technology's clinical applications doesn't exist. The investigators plan to compare OCTA as an imaging modality ...
