Reduction of Radiation Exposure in XXXX Ablation Using a New Image Integration Module: A Prospective Randomized Trial in @entity1 Undergoing Pulmonary Vein Isolation.

@entity1 @entity358 @entity943 @entity955
INTRODUCTION: Recently, a new image integration module (IIM, CartoUnivu    Module) has been introduced to combine and merge fluoroscopy images with 3-dimensional-(3D)-electroanatomical maps (Carto   3 System) into an accurate 3D view. The aim of the study was to investigate the influence of IIM on the fluoroscopy exposure during @entity358 ( @entity358 ) for @entity955 ( @entity955 ) in a prospective randomized trial. METHODS AND RESULTS: Between June and November 2014, a total of 60 @entity1 with @entity955 (73.3% male, 64.0    9.2 years), who underwent @entity358 with the endpoint of unexcitability of the ablation line, were randomized to either a conventional 3D mapping system (Carto   3 System) or to an additional IIM on the basis of an assumed reduction of fluoroscopy exposure by the use of IIM. There were no significant differences in baseline characteristics. The median ablation procedure time was identical in both groups (140.7    27.8 minutes vs. 140.8    39.5 minutes; P = 0.851). A significant decrease of mean fluoroscopy time from 11.9    2.1 to 7.4    2.6 minutes (P < 0.0006) and median fluoroscopy dose from 882.9 to 476.5 cGycm(2) (P < 0.001) was achieved. The main reduction of radiation could be realized during creation of the 3D-map. No major complications occurred during the procedures. After a median follow-up of 125.7    45.6 days 80% of the @entity1 were free from any @entity943 . CONCLUSION: CartoUnivu    module easily integrates into the workflow of @entity358 with the endpoint of unexcitability of the ablation line without prolonging the procedure time. It is associated with a marked reduction in fluoroscopic dose when compared to a conventional 3D mapping system.
