    3. Thin-Cap Fibroatheroma Rather Than Any Lipid Plaques Increases the Risk of Cardiovascular Events in Diabetic Patients: Insights From the COMBINE OCT–FFR Trial

      Thin-Cap Fibroatheroma Rather Than Any Lipid Plaques Increases the Risk of Cardiovascular Events in Diabetic Patients: Insights From the COMBINE OCT–FFR Trial
      Background: Autopsy studies have established that thin-cap fibroatheromas (TCFAs) are the most frequent cause of fatal coronary events. In living patients, optical coherence tomography (OCT) has sufficient resolution to accurately differentiate TCFA from thick-cap fibroatheroma (ThCFA) and not lipid rich plaque (non-LRP). However, the impact of OCT-detected plaque phenotype of nonischemic lesions on future adverse events remains unknown. Therefore, we studied the natural history of OCT-detected TCFA, ThCFA, and non-LRP ...

    8. Double-kissing nano-crush for bifurcation PCI guided by live OCT imaging: Shedding light on stent positioning

      Double-kissing nano-crush for bifurcation PCI guided by live OCT imaging: Shedding light on stent positioning
      Percutaneous coronary intervention (PCI) of bifurcation lesions poses unique challenges and carries a high risk of adverse events on follow-up, mainly driven by repeat revascularization and stent thrombosis . Several techniques exist to tackle bifurcation lesions. Among those, double kissing (DK) crush has emerged in recent years as a safe and effective approach for complex bifurcations requiring a two-stent strategy. In its most recent iteration, the DK nano-crush, minimal (ideally less ...

      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 ...

  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."
