Background Only a few studies have systematically evaluated fluoroscopy data of electrophysiological and device implantation procedures. Aims this study were to quantify ionizing radiation exposure for electrophysiological/device procedures in large series patients analyze the x‐ray trend over years undergoing atrial fibrillation ablation considering different technical aspects. Methods Results We performed retrospective analysis all during past 7 modern, large‐volume laboratory. reported complete on 8150 (6095 2055 procedures); each type procedure, effective dose lifetime attributable risk cancer incidence mortality calculated. Over 7‐year period, we observed significant reduction time, area product, ( P <0.001) not statistically Analyzing 2416 ablations, variability product among experienced operators <0.0001) use time them. Considering techniques, was = 0.74) radiofrequency catheter comparison with cryoablation, though cryoablation still associated higher values <0.001). Conclusions Electrophysiological involve nonnegligible use, leading an increased malignancy. Awareness radiation‐related risk, together technological advances, can successfully optimize use.
