Alternative Methodology for Occupational Dose Estimation in Cardiac Electrophysiology Procedures

Fluoroscopy-guided cardiac electrophysiology procedures are among the most critical x-ray exposures. However, occupational doses still little-known. In this study, an alternative methodology was developed to estimate dose and evaluated its optimization in electro-physiology procedures. The were reproduced by simulation rates of staff measured at chest eyes height through electronic dosimeters. rate for different modes operation FOV evaluated. estimated product staff's position room, median time exposure mean these performed HCPA 2019. As a result, it observed that decreasing order Physician A - R Nursing Staff Radiographer B Supplier, with following values mSv/year 6.16 3.98 2.54 2.17, respectively. 37.04% reduction change FOV, up 59.26% acquisition 31.82% distancing 50 cm from exposed position. is significant. due protocols already implemented HCPA, accordance recommended limits. actions verified suggested proper selection adoption distance source.
