Why the study?
Although 3D nonfluoroscopic mapping systems are generally used for complex arrhythmias, the efficacy, safety, and long-term effect of their extended routine use for catheter ablation needed evaluation.
Does the routine use of 3D nonfluoroscopic mapping systems reduce radiation exposure compared to fluoroscopy in patients undergoing catheter ablation?

Follow-up
12 months for AF CA procedures and 3 months for SVT CA

Routine NMS use links to lower radiation exposure in CA without affecting survival; extends observational data but leaves open need for RCTs.
Does the routine use of 3D nonfluoroscopic mapping systems reduce radiation exposure compared to fluoroscopy in patients undergoing catheter ablation?
The routine use of 3D nonfluoroscopic mapping systems for catheter ablation dramatically reduces radiation exposure without compromising procedure time or clinical efficacy.
