      Subintimal Versus Intraplaque Recanalization of Coronary Chronic Total Occlusions: Mid-Term Angiographic and OCT Findings From the ISAR-OCT-CTO Registry
      Objectives The aim of this study was to compare angiographic and optical coherence tomography findings following subintimal as opposed to intraplaque recanalization of chronic total occlusions (CTOs). Background There is ongoing controversy regarding outcomes of intraplaque versus subintimal CTO recanalization. Methods Consecutive patients undergoing angiography and intravascular optical coherence tomography following CTO recanalization were included in the ISAR-OCT-CTO (Intracoronary Stenting and Angiographic Results - Optical Coherence Tomography for Chronic Total Occlusions ...

    5. Optical coherence tomography tissue coverage and characterization with grey-scale signal intensity analysis after bifurcation stenting with new generation bioabsorbable polymer drug-eluting stent

      Optical coherence tomography tissue coverage and characterization with grey-scale signal intensity analysis after bifurcation stenting with new generation bioabsorbable polymer drug-eluting stent
      Purpose Bifurcation stenting is thought to be associated with delayed healing and a subsequent risk of stent failure. The aim of this study was to further evaluate healing of thin-strut bioabsorbable polymer everolimus-eluting stents (EES) post bifurcation stenting by optical coherence tomography (OCT) including grey-scale signal intensity (GSI) analysis. Methods Patients receiving bifurcation stenting with a planned two-stent approach using EES with OCT follow-up at 36 months post-stenting were included ...

    6. Process control and quality assurance in remote laser beam welding by optical coherence tomography

      Process control and quality assurance in remote laser beam welding by optical coherence tomography
      Remote laser beam welding significantly outperforms conventional joining techniques in terms of flexibility and productivity. This process benefits in particular from a highly focused laser radiation and thus from a well-defined heat input. The small spot sizes of high brilliance laser beam sources, however, require a highly dynamic and precise positioning of the beam. Also, the laser intensities typically applied in this context result in high process dynamics and in ...

    7. Inline weld depth measurement for high brilliance laser beam sources using optical coherence tomography

      Inline weld depth measurement for high brilliance laser beam sources using optical coherence tomography
      As a result of the rapidly growing importance of applications in electro mobility that require a precisely defined laser weld depth, the demand for inline process monitoring and control is increasing. To overcome the challenges in process data acquisition, this paper proposes the application of a novel sensor concept for deep penetration laser beam welding with high brilliance laser sources. The experiments show that optical coherence tomography (OCT) can be ...

    8. Qualitative and quantitative neointimal characterization by optical coherence tomography in patients presenting with in-stent restenosis

      Qualitative and quantitative neointimal characterization by optical coherence tomography in patients presenting with in-stent restenosis
      Aims To describe optical coherence tomography (OCT) findings in patients with in-stent restenosis (ISR) and determine predictors of neointimal patterns and neoatherosclerosis. Methods and results Patients undergoing OCT prior to PCI for ISR in three European centres were included. Analyses were performed in a core laboratory. Qualitative and quantitative [gray-scale signal intensity (GSI)] neointima analyses were performed on a per quadrant basis. A total of 107 patients were included. Predominantly ...

    9. Optical coherence tomography revisited: imaging and imagination

      Optical coherence tomography revisited: imaging and imagination
      Optical coherence tomography (OCT) was introduced into cardiovascular imaging in 1997 1 , emerging as a spin-off from an original scientific invention within the field of ophthalmology to enable imaging of retinal microstructures including arterioles and to facilitate detection of early degenerative changes of retinopathies. Consequently, OCT was praised as being a ground-breaking imaging technology which provides a far superior resolution as compared to the already established ultrasound-based imaging system (intravascular ...

      Multiple sclerosis: is it all black and white in optical coherence tomography?
      This scientific commentary refers to Brain and retinal atrophy in African-Americans versus Caucasian-Americans with multiple sclerosis: a longitudinal study, by Gonzalez Caldito et al. (doi: 10.1093/brain/awy245 ). ... Multiple sclerosis is an inflammatory demyelinating disease of the CNS. Histopathologically, degenerative processes have also been identified early in the disease course and independent of the demyelinating white matter disease. MRI of brain atrophy is currently the gold standard to assess ...

      Ultra low noise Fourier domain mode locked laser for high quality megahertz optical coherence tomography
      We investigate the origin of high frequency noise in Fourier domain mode locked (FDML) lasers and present an extremely well dispersion compensated setup which virtually eliminates intensity noise and dramatically improves coherence properties. We show optical coherence tomography (OCT) imaging at 3.2 MHz A-scan rate and demonstrate the positive impact of the described improvements on the image quality. Especially in highly scattering samples, at specular reflections and for strong ...

      Towards Robotic Eye Surgery: Marker-free, Online Hand-eye Calibration using Optical Coherence Tomography Images
      Ophthalmic microsurgery is known to be a challenging operation, which requires very precise and dexterous manipulation. Image guided robot-assisted surgery (RAS) is a promising solution that brings significant improvements in outcomes and reduces the physical limitations of human surgeons. However, this technology must be further developed before it can be routinely used in clinics. One of the problems is the lack of proper calibration between the robotic manipulator and appropriate ...

      Objectives The purpose of this study was to assess neoatherosclerosis in a registry of prospectively enrolled patients presenting with stent thrombosis using optical coherence tomography . Background In-stent neoatherosclerosis was recently identified as a novel disease manifestation of atherosclerosis after coronary stent implantation. Methods Angiography and intravascular optical coherence tomography were used to investigate etiologic factors of neoatherosclerosis in patients presenting with stent thrombosis 1 year after implantation (very late stent ...

      Very late scaffold thrombosis: insights from optical coherence tomography and histopathology
      A 79-year-old male patient had a 2.512 mm bioresorbable vascular scaffold (Absorb BVS; Abbott Vascular, Santa Clara, CA, USA) implanted in the setting of the RIBS VI study protocol for in-stent restenosis of a 39 mm bare metal stent (AVE S670; Medtronic, Minneapolis, MN, USA) in January 2015, at which time point the patient presented with stable angina and positive exercise stress test (index procedure). The Absorb BVS was ...
