In plain language

In 65 patients undergoing atrial or ventricular arrhythmia ablation, an image integration mapping module cut fluoroscopy time and patient dose by about two-thirds without lengthening procedures. Staff dose was not measured, though less fluoroscopy likely lowers exposure for the electrophysiology (EP) team.

the abstract

What it found

  • The image integration module reduced fluoroscopy time in left atrial arrhythmia ablation compared with controls.

    Key figures: 5.2 minutes [interquartile range (IQR) 1.9;6.8] vs. 28.2 minutes [IQR 15.3;37.8], P<0.001

  • Fluoroscopy time was also reduced in ventricular tachycardia (VT) ablation.

    Key figures: 9.8 minutes [IQR 4.5;13.1] vs. 25.5 minutes [IQR 14.1;30.9], P = 0.013

  • Total dose area product was lower with the module for left atrial appendage (LAA) ablation.

    Key figures: 2,088 cGy*cm(2) vs. 5,893 cGy*cm(2), P< 0.001

  • Patient effective dose was lower with the module for LAA and VT ablation.

    Key figures: 4.1 vs. 11.8 mSv (LAA, P<0.001); 7.8 vs. 24.7 mSv (VT, P=0.025)

  • Procedure duration did not change significantly.

    Key figures: 174 ± 45 vs. 197 ± 36 minutes, P = 0.083 (LAA)

Limits to keep in mind

Small single-series study with a retrospective, non-randomized historical control group; only patient dose metrics reported, no staff dosimetry.

How this summary was made
