In plain language
In one center's 140 pacemaker and defibrillator implants, 3D mapping guidance cut fluoroscopy time and air kerma by roughly half or more versus standard fluoroscopy, without added complications. Staff dose was not measured but likely falls with less fluoroscopy.

What it found
3D mapping cut median fluoroscopy time for single chamber devices from 5.5 to 0.9 minutes.
Key figures: 5.5 min (IQR 3.8-8.1) vs 0.9 min (IQR 0.6-1.9), P < .001
Median air kerma for biventricular devices fell from 324 to 115 mGy with 3D mapping.
Key figures: 324 mGy (IQR 143-668.7) to 115 mGy (IQR 77-204), P = .014
Air kerma for single chamber devices fell from 15.4 to 4 mGy.
Key figures: 15.4 mGy vs 4 mGy, P < .001
Fluoroscopy time for dual-chamber and biventricular devices was roughly halved.
Key figures: 6.3 vs 3.3 min (P < .001); 28.6 vs 14.7 min (P = .009)
No procedural complications and no difference in lead thresholds at 3 months.
Limits to keep in mind
Single-center, nonrandomized comparison with a historical consecutive control group of 70 patients each; staff dose was not measured directly, only fluoroscopy time and air kerma.
