In plain language
In 200 patients having catheter ablation for supraventricular tachycardia, 3D mapping systems cut fluoroscopy time by about two thirds and patient dose area product by about three quarters, with similar success. Staff dose was not measured but would likely fall too.

What it found
Fluoroscopy time was markedly lower with non-fluoroscopic navigation than with conventional fluoroscopy.
Key figures: 10.8 ± 11.1 minutes vs. 32.0 ± 27.5 minutes; p < 0.001
Mean dose area product was about four times lower with non-fluoroscopic navigation, across all supraventricular tachycardia (SVT) subtypes.
Key figures: 5,382 ± 5,768 mGy*cm2 vs. 21,070 ± 23,311 mGy*cm2; p < 0.001
Procedural success was comparable between groups.
Key figures: 97.5% vs. 98.3%
One-year recurrence did not differ significantly.
Key figures: 5.2% vs. 4.2%
Procedure time was not significantly reduced overall, except for left-sided AVRT ablation.
Key figures: 79.2 minutes vs. 116.4 minutes; p = 0.001
Limits to keep in mind
Non-randomised single-cohort comparison with groups of unequal size (79 vs. 121) and possible selection differences; only patient dose metrics were measured, with no direct staff dosimetry.
