      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.

      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 ...

      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. A lesion was defined as the 4mm segment with the maximum amount of lipid core burden index (maxLCBI 4mm ) of ...

      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 ...

      Radiofrequency ablation lesion assessment using optical coherence tomography – a proof‐of‐concept study
      Background Radiofrequency catheter ablation (RFA) is an effective treatment for atrial fibrillation. However, ablation lesions are usually only assessed functionally. The immediate effect of RFA on the tissue is not directly visualized. Optical coherence tomography (OCT) is an imaging technique that uses light to capture high‐resolution images with histology‐like quality. Therefore, it might be used for high‐precision imaging of ablation lesions. Methods and Results Radiofrequency ablation lesions ...

      Comparison of Optical Coherence Tomography-derived Minimal Lumen Area, Invasive Fractional Flow Reserve and FFRCT
      Significant left main (LM) stenosis is associated with a poor prognosis, therefore, adequate judgement of the prognostic significance of LM stenosis is essential to improve patients' prognosis. Recently, fractional flow reserve (FFR) has become widespread practice and carries a Class Ia recommendation to assess functional significance of intermediate coronary stenosis in patients with stable angina. Intravascular ultrasound (IVUS)-derived minimum lumen area (MLA) represents an accurate measure to determine LM ...
