Why we started
When performing a cardiac catheterization using the radial artery for access, it is widely known that radiation exposure to the operating physician is higher than using the femoral artery. With the increasing popularity of radial access, the resulting greater radiation exposure for operating physicians is a major concern, and a growing body of evidence suggests the side effects can be severe, including a relatively higher incidence of tumors among interventional cardiologists.
Current standard equipment such as lead aprons and above-table shields provide some radiation protection, however, radiation gaps persist, leaving operators vulnerable to exposure, especially in cases involving radial access. It is common for cardiac catheterization labs to use non-specific arm support devices when gaining access to the radial artery. These devices are clumsy, unprofessional, and uncomfortable for the patient. They tend to increase patient and operator radiation dose and degrade image quality due to the relative radiopacity and thickness of the materials used. They are also inconvenient as they must be removed between cases or once the procedure begins, to avoid contaminating the sterile field.
Working within a radial-focused center at a hospital in London, Ontario, and with our combined clinical knowledge and expertise, we sought to design a radial armboard that addressed all these issues, while supporting some additional key features. Our first goal was to reduce radiation exposure to operators without interfering with their ability to perform interventional procedures. We also added elements that facilitate equipment handling during procedures and address the support challenges associated with left radial access. The resulting sleek form factor allows the arm board to remain in position both during femoral access procedures and between cases.
Our radial armboards optimize safety and function with both the operator and patient's needs in mind. Every detail has been carefully considered and continuously redesigned based on real-world experience and evidence. It stands as the only radial armboard to be subjected to a real-world randomized trial, demonstrating a nearly 60% reduction in radiation exposure to the head and neck of the primary operator.
We are confident that you too will see the many advantages that our devices will bring to your cath lab.
