In plain language
In 32 patients undergoing cryoballoon ablation for atrial fibrillation, using a dedicated inner lumen mapping catheter shortened fluoroscopy time by about 8 minutes and procedure time by about 29 minutes. Staff dose was not measured.

What it found
Fluoroscopy time was shorter with the inner lumen mapping catheter than with the standard approach.
Key figures: 24.4 ± 10 minutes vs 32.6 ± 11 minutes, P = 0.04
Procedure duration was shorter with the inner lumen mapping catheter.
Key figures: 96.6 ± 26 minutes vs 125.9 ± 25 minutes, P = 0.003
Pulmonary vein isolation rates were similar between groups.
Key figures: 97% vs 94%, P non-significant
Limits to keep in mind
Small non-randomized comparison of 16 consecutive patients against 16 prior consecutive controls; radiation was measured only as fluoroscopy time, with no staff dose measured.
