Ultra-low radiation dose during electrophysiology procedures using optimized new generation fluoroscopy technology

Area of Science:

• Cardiology
• Medical Imaging
• Radiation Safety

Background:

• Electrophysiology (EP) procedures necessitate fluoroscopic guidance, posing risks from ionizing radiation.
• Advanced fluoroscopy systems offer enhanced dose-reduction capabilities.
• This study compares radiation dose between older and newer fluoroscopy systems in EP labs.

Purpose of the Study:

• To evaluate radiation dose reduction using a new, optimized fluoroscopy system compared to an older one.
• To assess the impact of dose-reduction strategies in contemporary digital fluoroscopy.

Main Methods:

• Radiation dose data collected over two years in an EP laboratory.
• Procedures categorized into seven distinct groups.
• Comparison between an older system (Year 1) and a new system with dose reduction (Year 2).

Main Results:

• Overall dose area product (DAP) decreased by 91% with the new system (5.0 to 0.45 Gycm²).
• Radiation dose reductions were observed across all procedure groups.
• New system's DAP levels are among the lowest reported in the literature.

Conclusions:

• Optimized contemporary digital fluoroscopy systems can achieve ultra-low radiation levels.
• Low radiation dose configurations, combined with good practice, are effective in EP procedures.
• Procedural time and success are maintained with advanced, low-dose fluoroscopy systems.
