Key result
NavX-guided ablation of common-type atrial flutter significantly reduced fluoroscopy time (5.1 vs 20 min, P<0.01) and total x-ray exposure compared to a conventional fluoroscopy-guided approach.
Why the study?
Does NavX-guided ablation reduce fluoroscopy time and radiation exposure compared to fluoroscopy-guided ablation in patients with common-type atrial flutter?
Population
40 consecutive patients with documented common-type atrial flutter (AFL), mean age 59 ± 12 years, 32 male.
Comparison
NavX-guided catheter ablation, including 3D… vs Fluoroscopy-guided catheter ablation.

NavX-guided ablation of atrial flutter significantly reduces fluoroscopy time and radiation exposure without prolonging procedure time compared to conventional fluoroscopy.
Ventura et al. (2004) conducted an RCT in common-type atrial flutter (AFL) (n=40). NavX-guided ablation vs. Fluoroscopy-guided ablation was evaluated on Fluoroscopy time (min) (p=<0.01). NavX-guided ablation of common-type atrial flutter significantly reduced fluoroscopy time (5.1 vs 20 min, P<0.01) and total x-ray exposure compared to a conventional fluoroscopy-guided approach.
