    3. Bifurcation and Ostial Optical Coherence Tomography Mapping (BOOM) – Case Description of a Novel Bifurcation Stent Technique

      Bifurcation and Ostial Optical Coherence Tomography Mapping (BOOM) – Case Description of a Novel Bifurcation Stent Technique
      Stent placement guided by angiography alone is often inexact, but of increased importance with bifurcation percutaneous coronary intervention (PCI). We describe a novel technique using optical coherence tomography (OCT)-guided angiographic co-registration termed Bifurcation and Ostial OCT Mapping (BOOM). The technique is based on the precise identification and mapping of the side-branch ostium using co-registration to minimize protrusion of stent struts into the main branch while ensuring full coverage of ...

    8. Convolutional neural network based automatic plaque characterization for intracoronary optical coherence tomography images

      Convolutional neural network based automatic plaque characterization for intracoronary optical coherence tomography images
      Optical coherence tomography (OCT) can provide high-resolution cross-sectional images for analyzing superficial plaques in coronary arteries. Commonly, plaque characterization using intra-coronary OCT images is performed manually by expert observers. This manual analysis is time consuming and its accuracy heavily relies on the experience of human observers. Traditional machine learning based methods, such as the least squares support vector machine and random forest methods, have been recently employed to automatically characterize ...

    9. Combining IVUS and Optical Coherence Tomography for More Accurate Coronary Cap Thickness Quantification and Stress/Strain Calculations: A Patient-Specific Three-Dimensional Fluid-Structure Interaction Modeling Approach

      Combining IVUS and Optical Coherence Tomography for More Accurate Coronary Cap Thickness Quantification and Stress/Strain Calculations: A Patient-Specific Three-Dimensional Fluid-Structure Interaction Modeling Approach
      Accurate cap thickness and stress/strain quantifications are of fundamental importance for vulnerable plaque research. Virtual histology intravascular ultrasound (VH-IVUS) sets cap thickness to zero when cap is under resolution limit and IVUS does not see it. An innovative modeling approach combining IVUS and optical coherence tomography (OCT) is introduced for cap thickness quantification and more accurate cap stress/strain calculations. In vivo IVUS and OCT coronary plaque data were ...

  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."
