NavX should be prioritized to minimize radiation in ablations; extends RCT evidence for non-fluoroscopic mapping safety and efficacy.
Does non-fluoroscopic mapping (Carto or Ensite NavX) reduce X-ray exposure or improve outcomes compared to conventional mapping in patients undergoing catheter ablation for arrhythmias?
Non-fluoroscopic mapping systems, particularly Ensite NavX, significantly reduce X-ray exposure during catheter ablation without compromising procedural success or safety, though they increase disposable costs.
