    4. The Mystery of Spotty Calcification Can We Solve It by Optical Coherence Tomography?

      The Mystery of Spotty Calcification Can We Solve It by Optical Coherence Tomography?
      Spotty calcification has recently been introduced as a marker of plaque vulnerability in patients presenting with acute coronary syndrome undergoing invasive and noninvasive coronary imaging, 1 and it has been suggested to be of predictive value for percent atheroma volume with greater progression. 2 Several pathological and clinical studies applying computed tomography (CT) and intravascular ultrasound (IVUS) demonstrated that spotty calcification is more frequently observed in lesions with plaque rupture ...

      A Case of On-line Software-based Co-registration of Optical Coherence Tomography and Angiography Guided Percutaneous Coronary Intervention for a Patient With Angina Pectoris
      Recently developed imaging modalities provide precise and accurate evaluation of lesions within the coronary arteries. Among them, optical coherence tomography (OCT) provides higher resolution cross-sectional imaging than intravascular ultrasound [1]. Recently, software-based on-line co-registration of OCT and angiography has become available as a new tool in percutaneous coronary intervention. Here, we describe a case where this new modality was critical for successful percutaneous coronary intervention.

    14. Intravascular Imaging of Coronary Calcification and Its Clinical Implications

      Intravascular Imaging of Coronary Calcification and Its Clinical Implications
      Calcium impacts the natural history and treatment of coronary artery disease in many ways. Intravascular imaging studies, mostly intravascular ultrasound, but more recently studies using optical coherence tomography, have been instrumental in increasing our understanding of the relationship between calcium and coronary atherosclerosis, the predictors, the natural history of this relationship, and the impact on treatment. On one hand, stable coronary lesions are associated with more calcium than unstable lesions ...

  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."
