In plain language
In electrophysiology ablations and cardiac resynchronization therapy (CRT) implants, including over 600 procedures at one centre, a sensor-based catheter tracking system was linked to large reductions in fluoroscopy time, with efficacy reported as similar. Effects on the fluoroscopy team's dose were not measured.

What it found
For supraventricular tachycardia (SVT) ablation, fluoroscopy time with MediGuide was far lower than with conventional fluoroscopic settings.
Key figures: 0.5 ± 1.4 min vs 10.2 ± 9.6 min
For atrial fibrillation (AF) ablation, fluoroscopy time fell from 25 min with electroanatomical mapping and live x-ray to 4.6 min with MediGuide added.
Key figures: 25 min to 4.6 min
Using MediGuide for CRT implants gave a median fluoroscopy time of 2.6 min for LV lead deployment.
Key figures: median 2.6 min
The authors report that fluoroscopy was reduced without negative effects on efficacy, complications or procedure time in more than 600 electrophysiology (EP) procedures.
Key figures: >600 procedures
Limits to keep in mind
A narrative review combined with an uncontrolled single-centre experience report; most figures come from cited studies and no comparative data from the 600 procedures are given. Fluoroscopy time is a surrogate and staff dose was not measured.
