Radiofrequency ablation of arrhythmias guided by non-fluoroscopic catheter location: a prospective randomized trial

Abstract

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.

“…747,1186,1248,1249 This can only be achieved, however, by an awareness of the importance of reducing fluoroscopy time, and therefore radiation exposure, by the operator. 1250 It has been shown that use of optimized conventional fluoroscopy and optimized use of 3D mapping can result in a marked reduction in radiation exposure.…”

Safety and efficacy of cryoablation without the use of fluoroscopy

“…Subsequent to this, there were reports of RF ablation procedures performed entirely without the use of fluoroscopy in SVT [5,6,8,[17][18][19][20][21][22]. Casella et al [13] shows that RF ablation without the use of fluoroscopy in 38 patients with supraventricular arrhythmias (AFL, WPW syndrome, AVNRT and AT) is safe and successful.…”

“…In recent years, it was possible to perform more complex ablations with a significant reduction or even without using fluoroscopy [4][5][6][7][8][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Current Status and Future of Cardiac Mapping in Atrial Fibrillation

“…The other advantage is the effect on radiation exposure reduction. NavX is significantly higher than others in x-ray hazard reduction, median fluoroscopy time is 13 min conventionally, 6 min with CARTO, 4 min with NavX [23]. NavX system measures the local voltage on every standard intra-cardiac electrode and calculates the electrode position in 3D space.…”
