AIMS: To compare the utility of non-fluoroscopic mapping systems (Carto and Ensite NavX) with that of conventional mapping in @entity1 referred for catheter ablation of a wide variety of @entity943 . METHODS AND RESULTS: @entity1 referred for catheter ablation (excluding @entity955 , atypical @entity956 , @entity1165 in structural @entity299 ) were randomized equally to a procedure guided by Carto, Ensite NavX, or conventional mapping. A total of 145 @entity1 were recruited (82 @entity1 , aged 49+/-16, range 18-85). In 19 @entity1 , no ablation was performed, and in the remaining, typical @entity956 , atrioventricular nodal re-entrant @entity591 , and @entity591 [including Wolff-Parkinson-White (WPW)] accounted for 93% of ablations. Overall procedure time, immediate and short-term success, complication rate, and freedom from symptoms at follow-up were identical for all groups. NavX led to the least X-ray exposure: Navx vs. conventional, median (range): 4 (0-50) vs. 13 (2-46) min (P<0.001); NavX vs. Carto, median (range): 4 (0-50) vs. 6 (1-55) min (P=0.008). Both Carto and NavX increased disposable costs by 50% when compared with conventional (P<0.001). For typical @entity956 , Carto and NavX reduced screening times without increasing procedure cost. If ablation was not performed, NavX was twice as expensive as Carto or conventional. CONCLUSION: Ensite NavX and Carto procedures have similar effectiveness and safety to a conventional approach; however, they both reduce X-ray exposure, with NavX producing a significantly greater effect than Carto. Although this benefit is achieved at a greater financial cost, there may be long-term benefits to catheter laboratory staff.
