    2. OPtical Coherence Tomography Guided Coronary Stent IMplantation Compared to Angiography: A Multicenter Randomized TriaL in PCI

      OPtical Coherence Tomography Guided Coronary Stent IMplantation Compared to Angiography: A Multicenter Randomized TriaL in PCI
      AIMS: Randomized trials have demonstrated improvement in clinical outcomes with intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) compared with angiography-guided PCI. The ILUMIEN III trial demonstrated non-inferiority of an optical coherence tomography (OCT)- versus IVUS-guided PCI strategy in achieving similar post-PCI lumen dimensions. ILUMIEN IV is a large-scale, multicenter, randomized trial designed to demonstrate the superiority of OCT- versus angiography-guided stent implantation in patients with high-risk clinical characteristics (diabetes ...

    3. Unexpected Findings and Tailored Treatments of In-Stent Restenosis: Novel Insights from Optical Coherence Tomography

      Unexpected Findings and Tailored Treatments of In-Stent Restenosis: Novel Insights from Optical Coherence Tomography
      A 68-year-old man was admitted to our hospital with unstable angina. His medical history was remarkable for an acute myocardial infarction one year ago, treated with a zotarolimus-eluting stent (3.530 mm) in the mid right coronary artery. Coronary angiography showed a diffused in-stent restenosis (ISR) with haziness and filling defects (Figure 1A, Video 1). In order to identify the underlying mechanisms of ISR, optical coherence tomography (OCT) was performed ...

    4. Outcomes of Optical Coherence Tomography Compared With Intravascular Ultrasound and With Angiography to Guide Coronary Stent Implantation: One-Year Results from the ILUMIEN III: OPTIMIZE PCI trial

      Outcomes of Optical Coherence Tomography Compared With Intravascular Ultrasound and With Angiography to Guide Coronary Stent Implantation: One-Year Results from the ILUMIEN III: OPTIMIZE PCI trial
      Aims: In the ILUMIEN III trial, among 450 randomised patients with non-complex lesions undergoing percutaneous coronary intervention (PCI), optical coherence tomography (OCT) guidance led to greater stent expansion than angiography guidance, similar minimal stent area compared to both intravascular ultrasound (IVUS) guidance and angiography guidance, and lower rates of uncorrected dissection and malapposition than both IVUS guidance and angiography guidance. Whether these differences impact clinical outcomes is unknown. Methods and ...

    7. Deep neural networks for A-line-based plaque classification in coronary intravascular optical coherence tomography images

      Deep neural networks for A-line-based plaque classification in coronary intravascular optical coherence tomography images
      We develop neural-network-based methods for classifying plaque types in clinical intravascular optical coherence tomography (IVOCT) images of coronary arteries. A single IVOCT pullback can consist of 500 microscopic-resolution images, creating both a challenge for physician interpretation during an interventional procedure and an opportunity for automated analysis. In the proposed method, we classify each A-line, a datum element that better captures physics and pathophysiology than a voxel, as a fibrous layer ...

      Optical Coherence Tomography Findings in Patients with Coronary Stent Thrombosis: A Report of the PREvention of Late Stent Thrombosis by an Interdisciplinary Global European Effort (PRESTIGE) Consortium
      Background Stent thrombosis (ST) is a serious complication following coronary stenting. Intravascular optical coherence tomography (OCT) may provide insights into mechanistic processes leading to ST. We performed a prospective, multicenter study to evaluate OCT findings in patients with ST. Methods Consecutive patients presenting with ST were prospectively enrolled in a registry using a centralized telephone registration system. After angiographic confirmation of ST, OCT imaging of the culprit vessel was performed ...

    12. Suboptimal agreement between optical coherence tomography and near-infrared spectroscopy for identification of lipid-laden plaque

      Suboptimal agreement between optical coherence tomography and near-infrared spectroscopy for identification of lipid-laden plaque
      Recently developed intracoronary imaging techniques allow real-time, in vivo identification of lipid in atherosclerotic plaques. Optical coherence tomography (OCT), a light-based imaging technique with high axial resolution (10-20 m), identifies lipid-laden plaques as signal-poor regions with diffuse borders. A validation study performed versus histopathology confirmed the high sensitivity (90% to 94%) and specificity (90% to 92%) of OCT to identify lipid-laden plaques 1 . Near-infrared spectroscopy (NIRS) detects lipid-laden plaque by ...

      Intracoronary optical coherence tomography: Clinical and research applications and intravascular imaging software overview
      By providing valuable information about the coronary artery wall and lumen, intravascular imaging may aid in optimizing interventional procedure results and thereby could improve clinical outcomes following percutaneous coronary intervention (PCI). Intravascular optical coherence tomography (OCT) is a light-based technology with a tissue penetration of approximately 1 to 3 mm and provides near histological resolution. It has emerged as a technological breakthrough in intravascular imaging with multiple clinical and research ...

    14. Optical coherence tomography compared with intravascular ultrasound and with angiography to guide coronary stent implantation (ILUMIEN III: OPTIMIZE PCI): a randomised controlled trial

      Optical coherence tomography compared with intravascular ultrasound and with angiography to guide coronary stent implantation (ILUMIEN III: OPTIMIZE PCI): a randomised controlled trial
      Background Percutaneous coronary intervention (PCI) is most commonly guided by angiography alone. Intravascular ultrasound (IVUS) guidance has been shown to reduce major adverse cardiovascular events (MACE) after PCI, principally by resulting in a larger postprocedure lumen than with angiographic guidance. Optical coherence tomography (OCT) provides higher resolution imaging than does IVUS, although findings from some studies suggest that it might lead to smaller luminal diameters after stent implantation. We sought ...

    1. Imaging is more accurate, helps guide decisions and facilitates tailored therapy, especially in younger heart attack patients who more frequently have plaque erosion or non-atherosclerotic coronary artery disease.
      In Expert consensus published on use of imaging to guide heart attack treatment
    2. OCT technology has become increasingly important to help diagnose and treat patients with coronary artery disease. The ILUMIEN OPTIS system is a significant advancement in intravascular imaging technology allowing physicians to comprehensively assess more vessel in less time and more easily plan their PCI procedure. The three-dimensional format of the ILUMIEN OPTIS system provides a more true-to-life perspective of the arteries, which allows for individual decision making and precise guidance of stent placement to optimize coronary interventions.

    3. We are doing a high number of off-label-indication cases, patients and lesions are becoming more and more complex, with more calcification and much less guarantee that in 20 seconds with one balloon, you can have good apposition of the stent and a good job done. And in this case, we need to increase the level of accuracy at the time of implanting and at follow-up: OCT is a new possibility to obtain the best placement. This could be very important in the future.
