In plain language
In a registry of 188 patients with supraventricular tachycardia, ablation without fluoroscopy was completed in 179, with outcomes and procedure times similar to X-ray-guided ablation, allowing the electrophysiology team to work without lead aprons.

What it found
Most patients referred for the No-X-Ray approach completed ablation without any fluoroscopy.
Key figures: 179/188 patients; 9 protocol exceptions
Procedure times did not differ between the No-X-Ray and X-ray control groups.
Key figures: 63 ± 26 vs. 63 ± 29 minutes, P > 0.05
Major complications and acute and long-term success rates were similar between groups.
Key figures: complications 0% vs. 0%; acute success 98% vs. 98%; long-term 93% vs. 94%; P > 0.05
Staff stopped wearing lead aprons after the first 10 nonfluoroscopic cases.
Key figures: after first 10 cases
Limits to keep in mind
Non-randomized registry comparison with a larger X-ray control group; staff radiation dose and musculoskeletal outcomes were not measured, and countries are not stated in the abstract.
