    3. Clinical determinants of coronary artery disease burden and vulnerability using optical coherence tomography co-registered with intravascular ultrasound

      Clinical determinants of coronary artery disease burden and vulnerability using optical coherence tomography co-registered with intravascular ultrasound
      Objectives: We investigated clinical determinants of disease burden and vulnerability using optical coherence tomography (OCT) co-registered with intravascular ultrasound (IVUS) in a large cohort of patients. Methods: A total of 704 patients [44.5% with acute coronary syndromes (ACS)] underwent coronary intervention. IVUS plaque burden and OCT lipid, macrophage and calcium indices and the presence of thrombus, plaque rupture and thin-cap fibroatheroma (TCFA) were analyzed. Results: Median patient age was ...

    4. What are the PROSPECTs and clinical implications of vulnerable plaque?

      What are the PROSPECTs and clinical implications of vulnerable plaque?
      Despite the fact that it has been three decades since James Muller and his colleagues first proposed the concept of vulnerable plaque 1 and 18 years since Naghavi et al. published their consensus document summarizing the concepts behind vulnerable patients and vulnerable plaques, including classifications for clinical and pathological evaluation, 2 , 3 we still have much to learn about the clinical implications of vulnerable plaque ( Graphical Abstract ). Feasibility of vulnerable ...

    5. Comparison of 6‐month vascular healing response after bioresorbable polymer versus durable polymer drug‐eluting stent implantation in patients with acute coronary syndromes: A randomized serial optical coherence tomography study

      Comparison of 6‐month vascular healing response after bioresorbable polymer versus durable polymer drug‐eluting stent implantation in patients with acute coronary syndromes: A randomized serial optical coherence tomography study
      Objectives This study was conducted to use optical coherence tomography (OCT) to compare vascular healing between bioresorbable polymer (BP) and durable polymer (DP) everolimus-eluting stents (EES) in patients with acute coronary syndromes (ACS). Background Whether BP-EES induce better vascular healing compared to contemporary DP-EES remains controversial, especially for ACS. Methods In this prospective, randomized, non-inferiority trial, we used OCT to compare 6-month vascular healing in patients with ACS randomized to ...

    6. Intracoronary optical coherence tomography: state of the art and future directions

      Intracoronary optical coherence tomography: state of the art and future directions
      Optical coherence tomography (OCT) has been increasingly utilised to guide percutaneous coronary intervention (PCI). Despite the diagnostic utility of OCT, facilitated by its high resolution, the impact of intracoronary OCT on clinical practice has thus far been limited. Difficulty in transitioning from intravascular ultrasound (IVUS), complex image interpretation, lack of a standardised algorithm for PCI guidance, and paucity of data from prospective clinical trials have contributed to the modest adoption ...

    7. Optical Coherence Tomography in Acute Coronary Syndromes

      Optical Coherence Tomography in Acute Coronary Syndromes
      Advances in intravascular imaging have enabled assessment of the underlying plaque morphology in acute coronary syndromes, which allows for the initiation of individualized therapy. The atherothrombotic substrates for acute coronary syndromes consist of plaque rupture, erosion, and calcified nodule, whereas spontaneous coronary artery dissection, coronary artery spasm, and coronary embolism constitute rarer nonatherothrombotic etiologies. This review provides a brief overview of the data from clinical studies that have used intravascular ...

    9. Optical coherence tomography detection of vulnerable plaques at high risk of developing acute coronary syndrome

      Optical coherence tomography detection of vulnerable plaques at high risk of developing acute coronary syndrome
      Aims: The ability of optical coherence tomography (OCT) to detect plaques at high risk of developing acute coronary syndrome (ACS) remains unclear. The aim of this study was to evaluate the association between non-culprit plaques characterized as both lipid-rich plaque (LRP) and thin-cap fibroatheroma (TCFA) by OCT and the risk of subsequent ACS events at the lesion level. Methods and results: In 1378 patients who underwent OCT, 3533 non-culprit plaques ...

      Automatic Characterisation of Human Atherosclerotic Plaque Composition from Intravascular Optical Coherence Tomography Using Artificial Intelligence
      Background Intravascular optical coherence tomography (IVOCT) enables detailed plaque characterisation in-vivo, but visual assessment is time-consuming and subjective. Aims This study aims to develop and validate an automatic framework for IVOCT plaque characterisation using artificial intelligence (AI). Methods IVOCT pullbacks from 5 international centres were analysed in a corelab, annotating basic plaque components, inflammatory markers and other structures. A deep convolutional network with encoding-decoding architecture and pseudo-3D input was developed ...

      Intravascular Imaging-Guided Percutaneous Coronary Intervention: A Universal Approach for Optimization of Stent Implantation
      Despite consistent clinical data supporting the use of intravascular imaging with percutaneous coronary intervention, utilization remains low. A practical and standardized approach to incorporating intravascular imaging with percutaneous coronary intervention may overcome the barriers to utilization. This review focuses on basic image interpretation with intravascular ultrasound and optical coherence tomography and proposes an algorithmic approach to stent sizing and optimization. Incorporation of this strategic method for percutaneous coronary intervention may ...

      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 ...

      A case report of a coronary myocardial bridge with impaired full-cycle ratio during dobutamine challenge
      Background A myocardial bridge (MB) is a coronary variant in which an epicardial coronary artery tunnels through the myocardial band. Although MBs have been reported to cause ischaemia, physiological assessment of an MB has not been fully established. Case summary We encountered a case with exertional chest pain who underwent coronary angiography showing an MB at the mid-left anterior descending artery with systolic compression. Optical coherence tomography showed an MB ...

  2. About Cardiovascular Research Foundation

    Cardiovascular Research Foundation

    Cardiovascular Research Foundation (CRF) strives to improve the quality of life for patients with cardiovascular disease. Our goal is to advance the development and use of safe and effective minimally invasive cardiovascular treatments.  In addition to its world-renowned Core Labs, and the many ground-breaking studies and trials conducted under the Foundation's auspices each year, CRF also sponsors a number of patient-based special projects such as the Women's Health Initiative. Furthermore, through its Data Coordinating and Analysis Center, CRF maintains a vast database of clinical inquiry and outcomes. This important database has been created to track the real-world, long-term effectiveness of new treatment models.
    CRF's dedication to research and education is demonstrated at the annual Transcatheter Cardiovascular Therapeutics (TCT) symposium where CRF's distinguished faculty joins forces with more than 600 of the world's leading cardiologists to teach, share and discuss the latest techniques and developments in the field with over 11,000 symposium participants from across the globe. Where once it took years for such theories and practices to achieve currency in the medical community, TCT now ensures the timely dissemination of this critical body of research and therapeutic practice. It is an exchange, as Dr Leon says, "that influences the way hundreds of thousands of patients are treated every year."
