Study at CRT 2025 Demonstrates Superiority of EggNest™ Complete Radiation Protection System Compared to Rampart Defender System in Total Room Protection
WASHINGTON, March 10, 2025 /PRNewswire/ -- A study unveiled today, March 10, 2025, at the Cardiovascular Research Technologies (CRT) 2025 meeting in Washington, DC, has demonstrated that the EggNest Complete Radiation Protection System provides superior scatter radiation protection for the entire Cath lab team compared to the Rampart Defender System. Presented by Dr. Thom Dahle, an Interventional Cardiologist at CentraCare Heart & Vascular Center in St. Cloud, MN, the findings mark a significant advancement in occupational safety for interventional cardiology professionals.
The independent study sought to compare the effectiveness of the EggNest Complete and Rampart Radiation Reduction Systems in reducing radiation exposure around the x-ray table. Both systems aim to reduce the well-documented risks of scatter radiation exposure—an occupational hazard that disproportionately affects interventional physicians and staff—while eliminating the physical strain of traditional lead aprons. However, the results clearly favored EggNest, showcasing its ability to deliver comprehensive protection across all members of the procedural team, not just the primary operator.
The study looked at radiation exposure at 5 positions around the x-ray table, including the Primary Operator, Assistant, Nurse, Anesthesiologist and Electrophysiologist/Echocardiographer positions. Key findings included:
- Scatter radiation was not evenly distributed around the x-ray table, with dose rates at the head of the table greater than at other positions.
- While both the EggNest and Rampart Systems effectively suppressed scatter radiation for the Operator and Assistant positions, the EggNest Complete System was the only system to provide significant protection for the Anesthesiologist, Echocardiographer, Electrophysiologist and Nurse positions, highlighting EggNest's unique whole-team approach.
In the study, the EggNest System reduced radiation exposure by 80% for the Echo/EP and Anesthesia positions and 85% for the Nurse position over standard shielding, while Rampart offered no benefit vs. standard shielding at those positions. For the Operator position, EggNest reduced radiation exposure by 96% while Rampart reduced exposure by 86%. For the Assistant position, EggNest reduced exposure by 98% while Rampart reduced exposure by 95%.1
Dr. Dahle noted "A radiation protection system that provides protection for ALL members of the Cath lab team is key for the multitude of procedures performed in modern Cath labs. EggNest's seamless integration into procedural workflows makes it a no-brainer for labs looking to enhance their radiation protection without compromise."
Dr. Robert Wilson, Founder and Chief Executive Officer at Egg Medical, Inc., said "This study confirms that the EggNest Complete System sets the standard for next generation radiation safety. We work as a team in the Cath lab and protecting the entire team—not just the physician—is critical."
