Performance of a Radiation Protection Cabin During Implantation of Pacemakers or Cardioverter Defibrillators

Methods: We randomly and evenly assigned 60 patients undergoing implantations of permanent pacemakers or cardioverter defibrillators (ICD) with (a) a radiation protection cabin (cabin group, n = 30) versus (b) standard protection with a 0.5 mm lead-equivalent apron (control group, n = 30). Radiation exposure was measured using personal electronic dosimeters placed on the thorax, back, and head of the operator. Results: The patient, procedural, and device characteristics of the 2 study groups were similar. All procedures in the cabin group were performed as planned without increase in duration or complication rate compared with the control group. The mean radiation dose to the head, normalized for fluoroscopy duration, was significantly lower in the cabin (0.040 +/- 0.032 mu Sv/min) than in the control (1.138 +/- 0.560 mu Sv/min) group (p < 0.0001). The radiation doses to the thorax (0.043 +/- 0.027 vs 0.041 +/- 0.040 mu Sv/min) and back (0.038 +/- 0.029 vs 0.033 +/- 0.018 mu Sv/min) in the cabin versus control group (under the apron) were similar. Conclusions: The use of a radiation protection cabin markedly decreased the exposure of the operator to radiation, and eliminated the need to wear a lead apron, without increasing the procedural time or complication rate during implantation of pacemaker and ICD.
