In plain language
In 90 electrophysiology procedures, mostly flutter ablations, using the MediGuide catheter tracking system was associated with less than half the fluoroscopy time of conventional mapping. Staff dose was not measured, so the benefit to the electrophysiology (EP) team is inferred.

What it found
Fluoroscopy time was substantially lower with the MediGuide nonfluoroscopic tracking system than with conventional mapping systems.
Key figures: 8 vs. 21 min, p < 0.001
Procedure duration was shorter in the MediGuide group.
Key figures: 103 vs. 142 min, p = 0.03
No major complications occurred in either group.
MediGuide was associated with more than a 50% reduction in fluoroscopy time.
Key figures: >50% reduction
Limits to keep in mind
Small observational study of the first 45 cases with matched controls, mostly simple right atrial flutter ablations; only fluoroscopy time was reported, with no staff or patient dose measurements.
