This study aimed to compare radiation exposure to different body regions of providers (hand vs torso) during TAVR. We hypothesized that due to conventional TAVR techniques, radiation exposure will differ based on body region and TAVR approach transfemoral (TF) vs transaortic (TAo)
Methods: We performed a prospective cohort study assessing radiation exposure of providers in consecutive TAVR cases, all performed with transesophageal echocardiographic guidance under general anesthesia. Providers wore radiation dosimeters (ring and collar) specific to their role and TAVR approach. Data was assessed over an 8 month period; total radiation dose for each body region was assessed and standardized to the number of cases performed Results: Data was collected for 46 TF and 7 TAo TAVRs. The Interventional Cardiology team had a significantly greater hand radiation exposure compared with torso during the TF approach (50.7 mRem vs 12.7 mRem) and the Surgery team with the TAo approach (127.5 mRem vs 12.2 mRem). Overall provider radiation exposure was higher for TF vs TAo approaches
Conclusions: Provider hand radiation exposure per case is greater than that of the torso during both TF and TAo TAVR. Better awareness of hand position and reduction in fluoroscopy times should be considered to decrease the amount of hand radiation exposure of the operator.
