Effect of fluoroscopy frame rate on radiation exposure and in-hospital outcomes in three-dimensional electroanatomic mapping guided procedures.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFluoroscopic imaging involves exposure of the patients and the laboratory staff to ionizing radiation. One of the strategies that reduce such exposure in an electrophysiology laboratory is using a three-dimensional electroanatomic mapping (3D EAM) system for performing these procedures. In this analysis, we have analyzed the effect of fluoroscopy frame rate on the radiation exposure and in-hospital outcomes in ablation procedures performed under 3D EAM guidance.
methodsWe retrospectively analyzed all the ablation procedures performed under 3D EAM guidance at our institute from September 2015 to December 2018. The procedures were divided into two groups based on whether the procedures were performed before (pre) or after (post) January 26, 2018. After January 2018, fluoroscopy was used at a frame rate of 3.75 frames per second (fps). Radiation exposure indices and in-hospital outcomes were compared between the two groups.
resultsAblation procedures included in the analysis were ventricular arrhythmias (n = 192), atrial flutter (115), atrial tachycardia (AT) (43), and atrial fibrillation (AF) (30). Over the study period, there was a significant reduction in procedure time, fluoroscopy time, dose area product, and effective dose (ED) (
conclusionThe use of 3D EAM combined with decreasing the fluoroscopy frame rate significantly reduced the total radiation exposure without adversely affecting in-hospital outcomes.
