    4. Optical Coherence Tomography-guided Coronary Intervention and Optimal Use of Dual Anti-Platelet Therapy In Patients With Complex Lesions (OCCUPI Trial)

      Optical Coherence Tomography-guided Coronary Intervention and Optimal Use of Dual Anti-Platelet Therapy In Patients With Complex Lesions (OCCUPI Trial)
      There is no definite conclusive work about optimal duration of DAPT after PCI of complex lesions, which have been left at each operator's discretion. It is needed to be investigated how optimal duration of dual antiplatelet therapy will be decided in complex lesions. Also, the benefit of OCT-guided PCI assuming better stent optimization should be determined in complex PCI. In the study, we will explore the clinical implication of ...

      Comparison of Repeatability and Agreement between Swept-Source Optical Biometry and Dual-Scheimpflug Topography
      Purpose . To assess the repeatability and agreement of parameters obtained with two biometers and to compare the predictability. Methods . Biometry was performed on 101 eyes with cataract using the IOLMaster 700 and the Galilei G6. Three measurements were obtained per eye with each device, and repeatability was evaluated. The axial length (AL), anterior chamber depth (ACD), keratometry (K), white-to-white (WTW) corneal diameter, central corneal thickness (CCT), and lens thickness (LT ...

    9. A Case of Double Fovea Artifact Detected with Spectral-domain Optical Coherence Tomography

      A Case of Double Fovea Artifact Detected with Spectral-domain Optical Coherence Tomography
      Abstract Purpose In the present study, a case of double fovea artifact on spectral-domain optical coherence tomography (SD-OCT) was reported. Case summary A nine-year-old male presented with blurred vision of both eyes. His best corrected visual acuity (BCVA) was 20/20 in both eyes, and complete ophthalmologic evaluation including fundus examination and fundus photography revealed no abnormality in both eyes. He underwent SD-OCT imaging with the Cirrus HD-OCT. The Macular ...

    10. Optical Coherence Tomography and Stent Boost Imaging Guided Bioresorbable Vascular Scaffold Overlapping for Coronary Chronic Total Occlusion Lesion

      Optical Coherence Tomography and Stent Boost Imaging Guided Bioresorbable Vascular Scaffold Overlapping for Coronary Chronic Total Occlusion Lesion
      We report herein the optical coherence tomography (OCT) and stent boost imaging guided bioresorbable vascular scaffold (BVS) implantation for right coronary artery (RCA) chronic total occlusion (CTO) lesion. The gold standard for evaluating BVS expansion after percutaneous coronary intervention is OCT. However, stent boost imaging is a new technique that improves fluoroscopy-based assessments of stent overlapping, and the present case shows clinical usefulness of OCT and stent boost imaging guided ...

    11. Analysis of neointima development in flow diverters using optical coherence tomography imaging

      Analysis of neointima development in flow diverters using optical coherence tomography imaging
      Background Flow diverters are used for the treatment of intracranial aneurysms. Surface modification may decrease the thrombogenicity of flow diverters but the details are unknown. Optical coherence tomography (OCT) is an intravascular imaging test with high resolution which identifies neointimal growth over stents. We compared the development of neointima in a flow diverter and stents with and without surface modification in a swine model. Methods In this study we implanted ...

      Characteristics of Earlier Versus Delayed Presentation of Very Late Drug‐Eluting Stent Thrombosis: An Optical Coherence Tomographic Study
      Background The pathophysiology underlying very late drug‐eluting stent ( DES ) thrombosis is not sufficiently understood. Using optical coherence tomography, we investigated characteristics of very late stent thrombosis ( VLST ) according to different onset times. Methods and Results A total of 98 patients from 10 South Korean hospitals who underwent optical coherence tomography for evaluation of very late DES thrombosis were retrospectively included in analyses.
