In plain language
In 80 patients undergoing atrial fibrillation ablation, adding nonfluoroscopic catheter visualization cut fluoroscopy time and dose by roughly two thirds or more without longer procedures. Staff dose was not measured directly, so the suggestion to drop lead aprons is untested here.

What it found
Nonfluoroscopic catheter visualization markedly reduced mean fluoroscopy time compared with conventional mapping.
Key figures: 1.9 vs. 13.2 min, p < 0.001
Mean radiation dose was about one third with NFCV.
Key figures: 510 vs. 1549 Gycm2, p < 0.001
Procedural parameters were similar and complications were rare.
Key figures: 1 groin complication (1.3%)
Authors suggest electrophysiology (EP) staff could abandon lead protection after transseptal puncture when using the technology.
Limits to keep in mind
Small single-lab randomized trial measuring patient-level fluoroscopy time and dose rather than staff dosimetry; the claim that staff can abandon lead aprons is not directly supported by measured occupational dose.
