Award-winning publication: Radiation exposure in relation to the arterial access site used for diagnostic coronary angiography and percutaneous coronary intervention: a systematic review and meta-analysis

Published in: The Lancet


In 2016, heart disease remains the world's leading cause of death. Each year, over three million percutaneous coronary interventions (PCIs) are carried out, including 60 000 in Canada. The exposure to radiation that is inherent to PCIs involves certain risks for patients, particularly the risk of developing cancer in the long term. While radial access for PCIs has several advantages for patients, certain authors have affirmed that the technique leads to greater exposure. Guillaume Plourde's study has demonstrated that while the radial artery approach is associated with slightly higher levels of exposure to radiation, these levels are not clinically significant and the benefits of the technique—such as a reduction in mortality—far outweigh those associated with the femoral approach. In sum, the results could help improve care for patients with heart disease by modifying hemodynamics practices and are therefore of particular importance as the population ages and PCIs become increasingly accessible.
