2. Relation between plaque type and dissections at the edges after stent implantation: An optical coherence tomography study

   Explore Article International Journal of Cardiology (May 13 2010) Cardiology

   Abstract: Background: Stent implantation can create vessel damage such as edge dissections. The objectives were i) to evaluate the frequency of edge dissections after stenting visible by intracoronary optical coherence tomography (OCT) in comparison with angiography. ii) to assess with OCT the plaque type left at the stent edges after implantation, and iii) to study whether there is an association between plaque type and dissections at stent edges.Methods: Seventy-three consecutive ...

3. Combined optical coherence tomography and intravascular ultrasound radio frequency data analysis for plaque characterization. Classification accuracy of human coronary plaques in vitro

   Explore Article SpringerLink Home (Apr 15 2010) Cardiology

   This study was performed to characterize coronary plaque types by optical coherence tomography (OCT) and intravascular ultrasound (IVUS) radiofrequency (RF) data analysis, and to investigate the possibility of error reduction by combining these techniques. Intracoronary imaging methods have greatly enhanced the diagnostic capabilities for the detection of high-risk atherosclerotic plaques. IVUS RF data analysis and OCT are two techniques focusing on plaque morphology and composition. Regions of interest were selected ... (Read Full Article)

5. Imaging atherosclerotic plaque composition with intracoronary optical coherence tomography

   Explore Article Netherlands Heart Journal (Dec 2 2009) Cardiology

   Optical coherence tomography (OCT) allows highly accurate diagnosis of atherosclerotic plaques, including measurement of the thickness of fibrous caps, permitting an assessment of the risk of rupture. While the OCT image presents morphological information in highly resolved detail, it relies on interpretation by trained readers for the identification of tissue type. We developed a method for quantitative classification of atherosclerotic plaque constituents. The optical attenuation coefficient mu(t) distinguishes different tissue ... (Read Full Article)

   Explore Article Heart (Aug 9 2009) Cardiology

   Objective: To observe and characterise vessel injury post-stenting using optical coherence tomography (OCT), to propose a systematic OCT classification for periprocedural vessel trauma, to evaluate its frequency in stable vs unstable patients and to assess its clinical impact during the hospitalization period. Setting: stenting causes vessel injury. Design and interventions: All consecutive patients in whom OCT was performed after stent implantation were included in the study. Qualitative and quantitative assessment ... (Read Full Article)

   Explore Article Heart (Jul 27 2009) Cardiology

   Invasive coronary imaging techniques have improved our understanding of atherosclerosis and helped us to evaluate the effectiveness of new drugs and new intravascular devices. We have adopted and integrated them rapidly into our clinical decision making process in the catheterisation laboratory. So far, only significant lesions in the coronary angiogram have been treated either by percutaneous coronary intervention (PCI) or coronary bypass artery grafting (CABG), while normal looking coronary segments ...

9. Optical coherence tomography patterns of stent restenosis

   Explore Article American Heart Journal (Jul 23 2009) Cardiology

   Background Stent restenosis is an infrequent but poorly understood clinical problem in the drug-eluting stent era. The aim of the study was to evaluate the morphologic characteristics of stent restenosis by optical coherence tomography (OCT). Methods Patients (n = 24, 25 vessels) presenting with angiographically documented stent restenosis were included. Quantitative OCT analysis consisted of lumen and stent area measurement and calculation of restenotic tissue area and burden. Qualitative restenotic ... (Read Full Article)

    Aims: To assess the inter- and intra- observer reproducibility for strut count, strut apposition and strut tissue coverage measurements with optical coherence tomography (OCT).Methods and results: Ten drug-eluting stents (244 frames, 1712 struts) imaged with OCT nine months after implantation were analysed by two independent analysts. One of the analysts repeated the analysis of five stents (120 frames, 795 struts) one week later. Offline analysis was performed with the proprietary ... (Read Full Article)

    Explore Article www3.interscience.wiley.com (Jun 13 2009) Cardiology

    Objectives and background: Quantitative analysis of intracoronary optical coherence tomography (OCT) image data (QOCT) is currently performed by a time-consuming manual contour tracing process in individual OCT images acquired during a pullback procedure (frame-based method). To get an efficient quantitative analysis process, we developed a fully automatic three-dimensional (3D) lumen contour detection method and evaluated the results against those derived by expert human observers. Methods: The method was developed using ... (Read Full Article)

    Optical coherence tomography (OCT) is increasingly being applied to the coronary arteries. However, the risks associated with the imaging procedure are not yet well defined. The purpose of the present multicentre registry was to access the acute complicaitons associated with the clinical use of intera-coronary OCT in a large number of patients. (Read Full Article)
