    2. Optical coherence tomography enables more accurate detection of functionally significant intermediate non-left main coronary artery stenoses than intravascular ultrasound: A meta-analysis of 6919 patients and 7537 lesions

      Optical coherence tomography enables more accurate detection of functionally significant intermediate non-left main coronary artery stenoses than intravascular ultrasound: A meta-analysis of 6919 patients and 7537 lesions
      Objective Fractional flow reserve (FFR) is regarded as the gold standard for the physiological assessment of intermediate coronary artery stenoses. However, FFR does not allow assessment of plaque morphology and lesion geometry. Intracoronary imaging techniques such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) can help treatment planning by optimising stent implantation, which can improve patient outcomes. The aim of this meta-analysis is to compare the efficacy of IVUS ...

    4. The Effect of Stent Artefact on Quantification of Plaque Features Using Optical Coherence Tomography (OCT): A Feasibility and Clinical Utility Study

      The Effect of Stent Artefact on Quantification of Plaque Features Using Optical Coherence Tomography (OCT): A Feasibility and Clinical Utility Study
      Background Optical coherence tomography (OCT) can detect detailed plaque features in native coronary arteries. Stent struts cause shadows that partially obscure the vessel wall, but plaque features can still be seen. We investigated the impact of stent artefact on plaque quantification and whether the plaque behind struts is associated with microvascular dysfunction. Methods Patients retrospectively recruited from two centres, underwent OCT pre- and post-stenting on the same vessel segment. Lipid ...

      Mechanical performance and healing patterns of the novel sirolimus-eluting bioresorbable Fantom scaffold: 6-month and 9-month follow-up by optical coherence tomography in the FANTOM II study
      Objectives We aimed to evaluate the mechanical properties and healing patterns 6 and 9 months after implantation of the sirolimus-eluting Fantom bioresorbable scaffold (BRS). Background The Fantom BRS (Reva Medical, San Diego, USA) has differentiating properties including radiopacity, strut thickness of 125 m, high expansion capacity and has demonstrated favourable mid-term clinical and angiographic outcomes. Methods and results FANTOM II was a prospective, single arm study with implantation of the ...

    8. Measuring Barrett’s Epithelial Thickness with Volumetric Laser Endomicroscopy as a Biomarker to Guide Treatment

      Measuring Barrett’s Epithelial Thickness with Volumetric Laser Endomicroscopy as a Biomarker to Guide Treatment
      Background Radiofrequency ablation (RFA) treatment outcomes vary for unknown reasons. One hypothesis is that variations in Barretts epithelial thickness (BET) are associated with reduced RFA efficacy for thicker BET and strictures for thinner BET. Volumetric laser endomicroscopy (VLE) is an imaging modality that acquires high-resolution, depth-resolved images of BE. However, the attenuation of light by tissue and the lack of layering in Barretts tissue challenge BET measurements and the study ...

    9. 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

      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 ...

      Optical coherence tomography substudy of a prospective multicentre randomised post-market trial to assess the safety and effectiveness of the Firehawk cobalt-chromium coronary stent (rapamycin target-eluting) system for the treatment of atherosclerotic le
      Aims: Durable polymer drug-eluting stents (DP-DES) may contribute to persistent inflammation, delayed endothelial healing and subsequent late DES thrombosis. The aim of this optical coherence tomography (OCT) substudy was to compare healing and neointimal coverage of a novel bioabsorbable polymer sirolimus-eluting stent (Firehawk ) (BP-DES) versus the DP-DES (XIENCE) at 90 days in an all-comers patient population. Methods and results: The TARGET All Comers study is a prospective multicentre randomised post-market ...

      A formula to calculate the contrast volume required for optimal imaging quality in optical coherence tomography with non-occlusive technique
      Background: Non-occlusive technique is universally accepted for acquisition of coronary optical coherence tomography (OCT), but the amount of contrast infused is still inconsistently calculated. Proposed herein, is an empirical formula for accurate contrast volume calculation. Methods: In an observational prospective study, contrast volume of consecutive patients undergoing OCT was either calculated with formula, or eyeballed based on manufacturer recommendations. The quality of pullback, defined as % of high quality cross-sections (CS ...

    13. Spectral Domain-Optical Coherence Tomography Measurements in Alzheimer’s Disease: A Systematic Review and Meta-analysis

      Spectral Domain-Optical Coherence Tomography Measurements in Alzheimer’s Disease: A Systematic Review and Meta-analysis
      Topic Optical coherence tomography (OCT) is a non-invasive tool to measure specific retinal layers in the eye. The relationship of retinal spectral domain-OCT (SD-OCT) measurements with Alzheimers Disease (AD) and mild cognitive impairment (MCI) remains unclear. Hence, we conducted a systematic review and meta-analysis to examine the SD-OCT measurements in AD and MCI. Clinical Relevance Current methods of diagnosing early AD are expensive and invasive. Retinal measurements of SD-OCT, which ...

  2. About Erasmus University

    Erasmus Medical Center is the largest and most versatile of the eight university medical centers in the Netherlands. Erasmus MC wants to further extend its international reputation and become one of the twenty best medical institutes in the world by 2013.  Also see The Thoraxcentrum of the Erasmus University Medical Center was founded in 1971 and is an integrated organization of the departments of Cardiology and Cardiothoracic Surgery. The Thoraxcentrum is divided into six medical units and three scientific units: Cardio-Thoracic Surgery, Cardiology, and Biomedical Engineering. The focus of Thoraxcenter Biomedical Engineering is the imaging and diagnosis of cardiovascular disorders. This department is led by Prof. Dr. Ir. A.F.W. van der Steen. The Biomedical Engineering department brings together two technical specialities of the Thoraxcenter, namely: The Experimental Echocardiography group, which investigates the physical and technical aspects of ultrasound for cardiac diagnosis.  Erasmus University Rotterdam is an international knowledge workshop for critical thinking and academic training, driven by a strong focus on current social issues.  The Erasmus MC (medical center) is the university hospital of the city of Rotterdam, The Netherlands. It is affiliated with the Erasmus University.
