Occupational radiation dose during the trans-catheter aortic valve replacement procedure
Fluoroscopy is an x-ray-imaging technique used during medical procedures such as trans-catheter aortic valve replacement (TAVR). The use of fluoroscopy exposes medical personnel to x-rays scattered from the patient. In this study, radiation dose to personnel at University of Colorado Hospital was measured using Phillips DoseAware dosimeters. The primary physician (0.106 mSv), secondary physician (0.035 mSv), perfusionist (0.027 mSv) received highest median doses of the operating room (OR) personnel. The physicians’ relatively higher doses were expected because of their proximity to the isocenter ...
