ABSTRACT
Interventional cardiologists are increasingly exposed to radiation-induced hazards. The MAVIG shield is a lead-free drape and the RADPAD is a sterile, disposable, and lead-free shield, placed on the patient with the aim to minimize operator-received scatter radiation. The objective of the trial was to examine their efficacy in a real-world situation. We randomized 125 patients who underwent coronary procedures from the right femoral artery into 3 groups Control group (nâ¯=â¯48 [39%]) without additional protection, MAVIG lead shield (nâ¯=â¯38 [30%]) and RADPAD shield (nâ¯=â¯39 [31%]). Multiple radiation dosimeters were used in each case. All 3 groups were with similar baseline and procedural characteristics. Fluoroscopy time and number of views were similar in all 3 study groups. Compared with the standard (no shield) protection [3.5 ± 5.57 mSv], the scatter radiation was reduced by a factor of 5 for the MAVIG group [0.46 ± 1.6 mSv and pâ¯=â¯0.001] and a factor of 4 for the RADPAD group [1.16 ± 2.29 mSv and pâ¯=â¯0.01]. The physician's radiation decreased with the 2 shields, but only the MAVIG shield showed statistically significant lower radiation 0.49 ± 0.42 mSv in the standard group versus 0.26 ± 0.3 mSv in the MAVIG and 0.35 ± 0.44 mSv in the RADPAD (pâ¯=â¯0.135 for RADPAD and pâ¯=â¯0.005 for MAVIG). Patient's exposure was statistically similar to the control group. Although numerically there was an increase in radiation with the RADPAD and decrease with the MAVIG. CONCLUSIONS:
Our study found no statistically increase in patient radiation while the operator's radiation exposure was reduced. Decreasing scatter radiation can be done effectively using simple measurements and is of major importance.
