University of Ottawa Heart Institute is North America's First Clinical Site for Ultra-sophisticated X-Ray

    New Technology Cuts Radiation Exposure, Reduces Procedure Time, Lowers

    OTTAWA, April 16 /CNW Telbec/ - The University of Ottawa Heart Institute
(UOHI) has installed North America's first dual axis rotational cardiac X-ray
for clinical use, allowing physicians to more clearly locate and diagnose
blockage in the heart's arteries. The ultra-sophisticated equipment cuts
radiation exposure by 33%, reduces X-ray time by a similar amount and offers
other benefits.
    "The Heart Institute typically conducts 6,000 catheterizations each year
and we can further decrease the waiting period for our heart patients", said
Dr. Marino Labinaz, Director, Cardiac Catheterization Laboratory, UOHI. "As
part of our research mandate, we are also planning to investigate the full
impact of this advanced X-ray technology on patient risk and improved
    Diagnosing coronary blockage through a procedure called cardiac
catheterization is traditionally performed by taking six or seven different
X-ray views. In each case, dye is injected into the coronary artery. Each
injection takes time - to set up and to make the injection. With the new
rotational X-ray, only one injection is needed to cover all views, requiring
up to 20 per cent less dye. This is significant because the dye can cause
potential damage in patients with kidney problems.
    The new X-ray system quickly rotates around the patient, giving medical
teams the ability to more easily view live 3-D images of the arteries in a
manner that improves the quality of diagnosis and treatment. In turn, this
approach reduces the length of the procedure - leaving more time for other
patients and helping to boost patient throughput. The advanced nature of the
equipment also lowers the amount of radiation required to image the arteries
by up to 33%, helping to reduce potential radiation risks for patients.
    The X-ray system is part of a new generation of imaging equipment that
provides patients at the Heart Institute with improved accuracy and speed in
the diagnosis and treatment of coronary artery disease. The Heart Institute is
the first clinical site in North America and one of a handful of cardiac
catheterization facilities in the world to employ the dual axis rotational
    "Patients at the Heart Institute continue to benefit from the most
advanced practices, technologies and treatments in coronary artery disease,"
said Dr. Labinaz. "As this technology gets adopted elsewhere, our research
knowledge and experience will reduce the learning curve for other clinical
centres which, in turn, will benefit patients across the country."
