In plain language
In 59 atrial ablation patients at one centre, adding a fluoroscopy-integrating module to 3D mapping lowered fluoroscopy time and dose-area product by roughly a third to a half without lengthening procedures. Staff dose was not measured directly.

What it found
In pulmonary vein isolation (PVI), the fluoroscopy integrating system (FIS) reduced dose-area product after a short learning curve.
Key figures: 801.9 ±439.15 cGycm² vs. 1495 ±435.2 cGycm², p = 0.002
In PVI, fluoroscopy time was reduced with FIS.
Key figures: 361.6 ±181 s vs. 530.3 ±156.7 s, p = 0.039
In CTI ablation for atrial flutter, FIS roughly halved dose-area product (DAP) and reduced fluoroscopy time.
Key figures: DAP 269 ±128.7 vs. 524.3 ±288.4 cGycm², p = 0.002; FT 99.29 ±51.4 s vs. 153.9 ±76.6 s, p = 0.022
Procedure time was not significantly changed with FIS.
Key figures: PVI 121 ±26.7 vs. 135.6 ±23.2 min, p = 0.21; CTI 29.5 ±10 vs. 35.2 ±16.3 min, p = 0.23
Fluoroscopy before transseptal puncture or catheter placement was not reduced, since FIS only works once catheters are in the heart.
Limits to keep in mind
Small single-centre study with retrospective historical controls and one operator for PVI; the first 6 FIS cases were excluded. Only patient-side metrics (FT, DAP) were recorded; staff dose was not measured.
