    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 ...

    5. 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. Supporting evidence from optical coherence tomography for shortening dual antiplatelet therapy after drug-eluting stents implantation

      Supporting evidence from optical coherence tomography for shortening dual antiplatelet therapy after drug-eluting stents implantation
      Introduction : Dual antiplatelet therapy (DAPT) is required for coronary artery disease treated with drug-eluting stents (DES) implantation. Shortening DAPT duration would be beneficial for patients with high bleeding risk. Areas covered : Early healing patterns, especially stent strut coverage, assessed by optical coherence tomography (OCT) as a surrogate of neointima have been investigated to make decisions on whether short DAPT would be a safe alternative. This review evaluates the OCT evidence ...

    11. Plaque burden can be assessed using intravascular optical coherence tomography and a dedicated automated processing algorithm: a comparison study with intravascular ultrasound

      Plaque burden can be assessed using intravascular optical coherence tomography and a dedicated automated processing algorithm: a comparison study with intravascular ultrasound
      Aims Plaque burden (PB) measurement using intravascular optical coherence tomography (IVOCT) is currently thought to be inferior to intravascular ultrasound (IVUS). We developed an automated IVOCT image processing algorithm to enhance the external elastic lamina (EEL) contour. Thus, we investigated the accuracies of standard IVOCT and an IVOCT enhancement algorithm for measuring PB using IVUS as the reference standard. Methods and results The EEL-enhancement algorithm combined adaptive attenuation compensation, exponentiation ...

  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."
