      Peri-procedural stent thrombosis following bifurcational PCI of lipid-rich plaque: serial optical coherence tomography insights
      Pre-procedural optical coherence tomography (OCT) of the left anterior descending artery (LAD) in a 58-year-old man with unstable angina due to a stenosis involving LAD and first diagonal branch detected underlying mixed plaque, partially containing lipid in a circumferential distribution distal to the first diagonal branch (Figures A1-3). Bifurcational percutaneous coronary intervention with side-branch-stenting (double-kissing mini-crush: 2.0x18mm zotarolimus-eluting-stent (ZES) in diagonal branch, 2.25x38mm-ZES in LAD with post-dilation using ...

      Standardisation of optical coherence tomography angiography nomenclature in uveitis: first survey results
      Aim To standardise the nomenclature for reporting optical coherence angiography (OCT-A) findings in the field of uveitis. Methods Members of the International Uveitis Study Group, of the American Uveitis Society and of the Sociedad Panamericana de Infermedades Oculares that choose to participate responded to an online questionnaire about their preferred terminology when reporting on OCT-A findings in uveitis.

    7. Coronary Artery Occlusion Caused by Intramural Hematoma Due to In-Stent Dissection

      Coronary Artery Occlusion Caused by Intramural Hematoma Due to In-Stent Dissection
      A 54-year-old man developed ST-segment elevation myocardial infarction 1 week after percutaneous coronary intervention of the left anterior descending artery. Optical coherence tomography at the emergent percutaneous coronary intervention revealed an intramural hematoma extending from the in-stent dissection. We highlight that in-stent dissection, although generally considered a benign finding, can extend and cause intramural hematoma, resulting in coronary artery occlusion.

    8. Conjunctival Microangiopathy in Diabetes Mellitus Assessed with Optical Coherence Tomography Angiography

      Conjunctival Microangiopathy in Diabetes Mellitus Assessed with Optical Coherence Tomography Angiography
      Purpose : To detect and quantify conjunctival microangiopathy with optical coherence tomography angiography (OCTA). Methods : Imaging was performed in the temporal and nasal quadrant of the conjunctiva using a Heidelberg Spectralis spectral domain-OCT in OCTA mode adding a 25D lens to the standard 30 fundus lens. Images were acquired within a 10 5 cube at the limbus. Binary images were analyzed using ImageJ (Fiji software version 2.0) and an average ...

    9. Utility of Multimodality Intravascular Imaging and the Local Hemodynamic Forces to Predict Atherosclerotic Disease Progression

      Utility of Multimodality Intravascular Imaging and the Local Hemodynamic Forces to Predict Atherosclerotic Disease Progression
      Objectives This study sought to examine the utility of multimodality intravascular imaging and of the endothelial shear stress (ESS) distribution to predict atherosclerotic evolution. Background There is robust evidence that intravascular ultrasound (IVUS)-derived plaque characteristics and ESS distribution can predict, with however limited accuracy, atherosclerotic evolution; nevertheless, it is yet unclear whether multimodality imaging and ESS mapping enable more accurate prediction of coronary plaque progression. Methods A total of ...

      Randomized comparison of optical coherence tomography versus angiography to guide Bioresorbable vascular scaffold implantation: The OPTICO BVS stud
      Purpose We investigated whether optical coherence tomography (OCT)-guided bioresorbable vascular scaffolds (BVS) implantation can improve in-scaffold minimal lumen area (MLA) at 6-month compared with angiography guidance. Methods The OPTICO BVS was a randomized, international multicenter, assessor blind, superiority trial comparing OCT- versus angiography-guided percutaneous coronary intervention (PCI) (1:1 allocation) in patients with coronary artery disease undergoing Absorb BVS 1.1 implantation. The primary endpoint was in-scaffold MLA at ...

    11. Mechanism of Drug-Eluting Absorbable Metal Scaffold Restenosis: A Serial Optical Coherence Tomography Study

      Mechanism of Drug-Eluting Absorbable Metal Scaffold Restenosis: A Serial Optical Coherence Tomography Study
      Background: The pathomechanisms underlying restenosis of the bioabsorbable sirolimus-eluting metallic scaffold (Magmaris) remain unknown. Using serial optical coherence tomography, we investigated causes of restenosis, including the contribution of late scaffold recoil versus neointimal hyperplasia. Methods: Patients enrolled in BIOSOLVE-II undergoing serial angiography and optical coherence tomography (post-intervention and follow-up: 6 months and/or 1 year) were analyzed. Patients were divided into 2 groups according to angiographic in-scaffold late lumen loss ...

      In vivo relationship between near-infrared spectroscopy-detected lipid-rich plaques and morphological plaque characteristics by optical coherence tomography and intravascular ultrasound: a multimodality intravascular imaging study
      Aims We assessed morphological features of near-infrared spectroscopy (NIRS)-detected lipid-rich plaques (LRPs) by using optical coherence tomography (OCT) and intravascular ultrasound (IVUS). Methods and results IVUS-NIRS and OCT were performed in the two non-infarct-related arteries (non-IRAs) in patients undergoing percutaneous coronary intervention for treatment of an acute coronary syndrome.

    13. Correlation between in vivo near-infrared spectroscopy and optical coherence tomography detected lipid-rich plaques with post-mortem histology

      Correlation between in vivo near-infrared spectroscopy and optical coherence tomography detected lipid-rich plaques with post-mortem histology
      A 67-year-old female presented with an acute anterior STEMI and underwent percutaneous coronary intervention of the mid-left anterior descending (LAD) coronary artery. Following successful implantation of two drug-eluting stents with TIMI III flow, multimodality imaging using near-infrared spectroscopy with intravascular ultrasound (NIRS-IVUS) and optical coherence tomography (OCT) was performed in the LAD and right coronary artery (RCA) in the setting of an imaging study (A1 and B1).

      Optical coherence tomography diagnostic signs in posterior uveitis
      A diagnostic sign refers to a quantifiable biological parameter that is measured and evaluated as an indicator of normal biological, pathogenic, or pharmacologic responses to a therapeutic intervention. When used in translational research discussions, the term itself often alludes to a signs used to accelerate or aid in diagnosis or monitoring and provide insight into personalized medicine. Many new diagnostic signs are being developed that involve imaging technology. Optical coherence ...

      Clinical use of intracoronary imaging. Part 2: acute coronary syndromes, ambiguous coronary angiography findings, and guiding interventional decision-making: an expert consensus document of the European Association of Percutaneous Cardiovascular Intervent
      This consensus document is the second of two reports summarizing the views of an expert panel organized by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) on the clinical use of intracoronary imaging including intravascular ultrasound (IVUS), optical coherence tomography (OCT), and near infrared spectroscopy (NIRS)-IVUS. Beyond guidance of stent selection and optimization of deployment, invasive imaging facilitates angiographic interpretation and may guide treatment in acute coronary syndrome. Intravascular ...
