    2. Lipoprotein (a) level is associated with plaque vulnerability in patients with coronary artery disease: An optical coherence tomography study

      Lipoprotein (a) level is associated with plaque vulnerability in patients with coronary artery disease: An optical coherence tomography study
      Background High lipoprotein (a) [Lp(a)] levels are an independent factor for worse prognosis in patients with coronary artery disease (CAD). However, the association between serum Lp(a) level and coronary plaque vulnerability remains to be determined. Methods A total of 255 consecutive patients with CAD who underwent optical coherence tomography imaging of culprit lesions were included. Patients were divided into 2 groups according to their Lp(a) levels (the ...

    3. Zero-Contrast Optical Coherence Tomography- and Physiology-Guided Percutaneous Coronary Intervention for Severely Calcified Lesion

      Zero-Contrast Optical Coherence Tomography- and Physiology-Guided Percutaneous Coronary Intervention for Severely Calcified Lesion
      An 80-year-old man with severe kidney dysfunction (estimated glomerular filtration rate, 26 mL/min/1.73 m 2 ) not requiring hemodialysis presented with effort angina. Diagnostic angiography with minimum contrast showed a diffuse lesion in the proximal right coronary artery (RCA; Figure A ). On a later day, optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) with dextran injection was performed. Because multiple cracks were seen in the severely calcified ...

    4. Incidence, factors, and clinical significance of cholesterol crystals in coronary plaque: An optical coherence tomography study

      Incidence, factors, and clinical significance of cholesterol crystals in coronary plaque: An optical coherence tomography study
      Background and aims Intraplaque cholesterol crystal (CC) is recognized as a component of vulnerable plaques. However, the clinical characteristics of patients with CC and the impact of CC on clinical events remain unknown. Methods A total of 340 consecutive patients who underwent optical coherence tomography (OCT) imaging of culprit lesions were included in the study. CC was defined as a thin linear structure with high reflectivity and low signal attenuation ...

    5. Influence of corneal power on circumpapillary retinal nerve fiber layer and optic nerve head measurements by spectral-domain optical coherence tomography

      Influence of corneal power on circumpapillary retinal nerve fiber layer and optic nerve head measurements by spectral-domain optical coherence tomography
      AIM : To evaluate the influence of corneal power on circumpapillary retinal nerve fiber layer (cpRNFL) and optic nerve head (ONH) measurements by spectral-domain optical coherence tomography (SD-OCT). METHODS : Twenty-five eyes of 25 healthy participants (mean age 23.63.6y) were imaged by SD-OCT using horizontal raster scans. Disposable soft contact lenses of different powers (from ?11 to +5 diopters including 0 diopter) were worn to induce 2-diopter changes in corneal ...

    6. Speckle variance optical coherence tomography using an SS-OCT system and an extended k-sampling clock

      Speckle variance optical coherence tomography using an SS-OCT system and an extended k-sampling clock
      is vacant or filled with material having a refractive index different from the tissue, the observed structure is deformed significantly. This deformation artifact can be minimized by filling the cavity with liquid having a refractive index nearly equal to the tissue. Furthermore, by using dynamical OCT method, cavity image intensity can be significantly enhanced compared with the tissue. This image contrast improvement may allow imaging of cavity structures inside deep ...

    7. Low eicosapentaenoic acid to arachidonic acid ratio is associated with thin-cap fibroatheroma determined by optical coherence tomography

      Low eicosapentaenoic acid to arachidonic acid ratio is associated with thin-cap fibroatheroma determined by optical coherence tomography
      Background A low eicosapentaenoic acid (EPA)/arachidonic acid (AA) ratio is known to be associated with cardiovascular events. However, the relationship between the EPA/AA ratio and coronary plaque vulnerability assessed by optical coherence tomography (OCT) has not been examined thoroughly. This study examined the relationship between the EPA/AA ratio and coronary plaque vulnerability assessed by OCT in patients with acute coronary syndrome (ACS). Methods We evaluated 59 ACS ...

    8. Comparative Kitasato-type optical coherence tomography study of differences in scleral shapes between the superonasal and superotemporal quadrants

      Comparative Kitasato-type optical coherence tomography study of differences in scleral shapes between the superonasal and superotemporal quadrants
      Objective: To determine differences in the scleral shape between the superonasal and superotemporal quadrants, which are the sites of scleral flap creation in trabeculectomy, using anterior-segment optical coherence tomography (OCT). Methods: Thirty-eight eyes of 22 subjects without ocular diseases except for cataract or ametropia were enrolled. The mean patient age was 63.8 15.7 years (range, 2880 years). The same examiner captured all images using Kitasato-type anterior-segment swept-source OCT ...

    9. Feature Of The Week 12/8/2013: Tuning of Vernier Tuned DBR Lasers for Optical Comb Swept Source OCT

      Feature Of The Week 12/8/2013: Tuning of Vernier Tuned DBR Lasers for Optical Comb Swept Source OCT
      Monolithic Vernier tuned distributed Bragg reflector (VT-DBR) lasers are expected to become one of the most promising sources for optical comb swept source optical coherence tomography (SS-OCT) with reduced sensitivity roll-off due to a long coherence length, potential capability for a very fast A-scan rate, and low cost with monolithic structure. However, mainly four problems inhibited an ideal implementations: 1) frequencies deviate from the targeted values when scanned, 2) large ...

      Two-week interval optical coherence tomography: Imaging evidence on neointimal coverage completion after implantation of the endeavor zotarolimus-eluting stent
      Objective : To obtain imaging evidence by 2-week optical coherence tomography (OCT) on the completion of neointimal coverage (NIC; the percentage of stent strut coverage and thickness of the formed neointima) completion after implantation of the Endeavor zotarolimus-eluting stent (E-ZES). Background : Despite the fact that NIC is a cardinal process in the pathomechanism of late stent thrombosis, little imaging information is available on morphological changes thereof on a short-time interval basis ...
