In plain language
In 31 patients having atrial fibrillation ablation, MediGuide-guided transseptal puncture cut fluoroscopy time by about 80% compared with matched conventional cases. This may reduce exposure for the electrophysiology team, but staff dose was not measured.

What it found
Fluoroscopy time to double transseptal access was much shorter with MediGuide-assisted puncture than with conventional fluoroscopy-guided puncture.
Key figures: 26.65 ± 37.97 s vs 129.13 ± 37.77 s (P < 0.001)
Nearly all MediGuide-assisted transseptal attempts succeeded without switching to the conventional technique.
Key figures: 60 of 62 attempts (96.7%)
No major complications occurred in any procedure.
Limits to keep in mind
Small non-randomized study (31 MediGuide patients and 31 matched controls) at a single setting. Fluoroscopy time was the only radiation measure; staff dose was not measured.
