Aizer A, Qiu J, Cheng A, et al. Utilization of a Radiation Safety Time-Out Reduces Radiation Exposure During Electrophysiology Procedures. JACC: Clinical Electrophysiology. 2019;5(5):626-634.

This study sought to determine whether a radiation safety time-out reduces radiation exposure in electrophysiology procedures. Results of 1,040 patient cases were included. The median dose area product prior to time-out was 18.7 Gy∙cm2, and the median during the time-out was 14.7 Gy∙cm2, representing a 21% reduction (p = 0.007). The median reference point dose prior to time-out was 163 mGy, and during the time-out was 122 mGy (p = 0.011). The use of sterile disposable protective shields and ultrasound imaging for access increased significantly during the time-out.

In this study, we aimed to evaluate the efficacy of low rate fluoroscopy at 7.5 frames/s (FPS) compared with conventional 15 FPS, in reducing operator and patient radiation dose during TRA diagnostic coronary angiography (DCA) and percutaneous coronary interventions (PCI).
