 note = {Catheter ablation (ABL) for atrial fibrillation (AF) remains a complex procedure and may require long fluoroscopy time. Further time reduction is necessary. We conducted a retrospective, observational, cross-sectional, single-center study to compare procedure time and radiation exposure before and after fluoroscopy image integration module (IIM) installation for AF between April 2018 and October 2020. We reviewed 236 consecutive patients who underwent ABL at University of the Ryukyus Hospital. We performed ABL for AF for 81 patients (before IIM installation), 67 patients (after IIM installation). We analyzed 68 patients as non-IIM group, 56 patients as IIM group who underwent pulmonary vein isolation (PVI) and cavotricuspid isthmus (CTI) ABL for AF after the exclusion of patients with additional ABL. The procedure time, fluoroscopy time, and radiation dose were considered between both groups. The median PVI procedure time (1.50 [interquartile range {IQR} l.20-l.83]h vs. 1.33 [IQR 0.91-1.SO]h; P<0.05), total fluoroscopy time (36.6 [IQR 24.2-55.8]min vs. 24.0 [IQR 18.0-35.4]min; P<0.05), and radiation dose (125.73 [IQR 73.92-217.04]mGy vs. 77.58 [IQR 48.62-122.90]mGy; P<0.05) in the IIM group were significantly lower than those in the non-IIM group. The use of IIM resulted in shorter procedure time and less radiation exposure in ABL for AF.},
