May lower radiation exposure in CRT implantation; supports further evaluation but should not yet change practice.

Does an angiography system with image noise reduction technology reduce radiation dose in patients undergoing cardiac device implantation procedures?
Absolute Event Rate: 1544% vs 7252%
p-value: p=<0.001
Image noise reduction technology significantly reduces radiation exposure during cardiac device implantations, particularly in complex CRT procedures.
Hoffmann et al. (2017) conducted a cohort in Cardiac device implantation (n=279). Image noise reduction technology (INRT) vs. C-arm system with continuous and pulsed fluoroscopy was evaluated on Total dose area product (DAP) in CRT procedures (p=<0.001). Image noise reduction technology significantly lowered total dose area product during CRT implantation procedures compared to a standard C-arm system (1,544 vs 7,252 cGycm, P<0.001).
