Egg Medical, Inc. has unveiled promising findings regarding its EggNest Complete Radiation Protection System, which significantly reduces radiation exposure for cath lab teams. During the 2025 Transcatheter Cardiovascular Therapeutics® (TCT) Conference in San Francisco, Dr. Jarrod Frizzell from The Christ Hospital in Cincinnati, OH shared real-world studies that illustrate the system”s efficacy compared to traditional shielding methods.
In interventional cardiology, scatter radiation is a well-established occupational hazard for staff, heightening the risk of serious health issues such as cancer, cataracts, and cardiovascular disease. While conventional lead aprons provide some measure of protection, they have also been associated with a high incidence of orthopedic injuries among healthcare professionals.
The studies highlighted by Dr. Frizzell indicated that the average scatter radiation dose for operators using the EggNest Complete System during coronary and PCI procedures was a mere 0.16 mRem per case. To put this into perspective, the annual occupational radiation exposure limit in the United States is 5,000 mRem. This means an operator would have to conduct over 31,000 procedures to approach that limit, while typical interventionalists perform around 300 to 500 cases each year. This innovative technology allows them to carry out their work with minimal radiation exposure, often eliminating the need for cumbersome lead aprons.
The data also underscored the team-wide protective capabilities of the EggNest system, as nurses and technologists recorded average exposures of just 0.03 mRem per case. Dr. Frizzell expressed the significance of this development, stating, “Having a radiation protection system that consistently protects my entire team as well as or better than the heavy lead we wore in the past means we”re taking care of patients and ourselves.”
Dr. Robert Riley, Chief Scientific Advisor for Egg Medical and an interventional cardiologist at Overlake Medical Center in Seattle, WA, reinforced the findings by saying, “These real-world results reinforce what prior studies have shown — the EggNest Complete System is the only solution proven to significantly reduce radiation exposure for every member of the team. By enabling staff to perform procedures with ultralight or no lead aprons, we can also dramatically reduce orthopedic injuries associated with traditional protection.”
Moving forward, Dr. Frizzell and his colleagues plan to continue their evaluation of the EggNest system in various procedures, including structural heart interventions and electrophysiology, thereby broadening the evidence supporting its use across a diverse array of X-ray–guided medical interventions.
Egg Medical, headquartered in Minnesota, is recognized as a leader in radiation protection technologies. The company aims to minimize scatter radiation exposure for medical professionals who utilize X-ray imaging during critical diagnostic and therapeutic procedures.
