The Effect Of Electroanatomic Imaging On Fluoroscopic Exposure In Catheter Ablation Of Cardiac Arrhythmias PDF Download

Background: Atrial fibrillation is a growing problem among the population worldwide. For ablation of atrial fibrillation, fluoroscopic imaging is generally essential for visualization purposes. The usage of x-rays can lead to various adverse effects like cancer.The aim of this master ́s thesis was to evaluate, if the use of electroanatomic 3D imaging technologies leads to a reduction in fluoroscopic exposure, compared to cryoablation.Methods: A retrospective, single-center study was conducted to compare the use of RF ablation (including a 3D mapping system) with cryoablation in pulmonary vein isolation. The primary endpoint is the mean dose area product in μGy*m2. Secondary endpoints are comparisons of body mass indices, the fluoroscopic exposure time (min), an analysis of the subgroups (paroxysmal and persistent AF) and the effect of an ultra low dose fluoroscopy program.Results: Of the 284 patients that were encompassed in the study, 167 underwent pulmonary vein isolation with RF ablation and the use of a 3D mapping system. 117 were treated with cryoablation to achieve pulmonary vein isolation.The use of RF ablation with a 3D mapping system resulted in a dose area reduction of 51.67% (2369.73 μGy*m2 vs. 4903.51 μGy*m2), compared to cryoablation, including all procedures between August 2015 and December 2017.Conclusion: The use of RF ablation including imaging with a 3D mapping system resulted in a reduction of the mean dose area product in the ablation of atrial fibrillation, compared to the usage of cryoablation.*****Background: Atrial fibrillation is a growing problem among the population worldwide.
