ControlRad Cut Radiation Exposure to Physicians by More than Half in Beaumont Study

Data presented at cardiology conference showed 57% reduction to primary physicians, trending greater in interventional procedures

ATLANTA, November 22, 2021 – Beaumont Hospital’s Chief of Cardiovascular Medicine, Dr. Simon Dixon, announced positive data for the ControlRad system at the Nov. 5th Transcatheter Cardiovascular Therapeutics (TCT) Annual Meeting.

The results of Beaumont Health’s prospective and randomized study were presented in Orlando at one of the largest educational gatherings of interventional cardiologists in the world.

The study found a 57% decrease in radiation exposure to the thyroid of the primary cardiologist (closest to the X-ray source) and a 49% reduction in dose to the secondary cardiologist’s thyroid during procedures using ControlRad. When looking at interventional procedures, primary cardiologists’ radiation exposure showed a trending reduction of 71% when using the technology. The study also resulted in a 35% reduction in dose area product (DAP) representing radiation to the patient and a 38% dose reduction to the dosimeter badge placed on the cath lab wall.

“If a nurse or tech is standing at the wall, that’s a nearly 40% decrease in radiation exposure,” Dr. Dixon said. “Radiation exposure for the cardiologist is a real concern, but so is exposure for staff. Cath lab nurses, anesthesiologists, physician assistants and others go into case after case as the doctors rotate. Protecting them is a real challenge.”

The study, which enrolled 80 cardiac catheterizations and/or percutaneous coronary interventions, concluded that the ControlRad technology reduces radiation exposure to the operators and patient during diagnostic and interventional cardiac catheterization procedures.

“For medical team members doing cath lab procedures, radiation exposure over days, weeks and years is a serious health concern as they take care of patients,” said Dr. Dixon. “Mitigating that exposure can help reduce health care workers’ higher incidence of cancer and cataracts over their lifetime.”

Beaumont Hospital Royal Oak is the largest health system in Michigan and ranked one of the best in the nation for cardiology and heart surgery by U.S. News and World Report.

The FDA-cleared ControlRad Select is commercially available through Boston Scientific and retrofits on facilities’ existing Siemens imaging systems.
