Utility of a ripple map for the interpretation of atrial propagation during atrial tachycardia.

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
purposeRipple map (RM) is a novel method for displaying activation pattern on the surface of a cardiac chamber. The aim of this study was to determine the utility of the RM in interpreting the atrial propagation in atrial tachycardia (AT) in comparison with a conventional local activation (LAT) map.
methodsThree-dimensional electroanatomical mapping and ablation of AT were performed using multielectrode catheters and the CARTO3 ConfiDENSE Module (Biosense Webster). LAT maps and RMs were retrospectively reviewed by two independent observers who were blinded to the ablation results.
resultsHigh-density maps (1683 ± 1362 points) of 45 ATs (274 ± 64 ms; macroreentry 28, focal 17) were obtained in 39 patients. Of the 45 ATs, 41 (91%) were terminated by catheter ablation. A retrospective review of the LAT map alone by two observers resulted in correct diagnosis in 27% (12 ATs), whereas additional reviews of the RMs improved the diagnostic accuracy to 80% (36 ATs, P < 0.001). The diagnostic accuracy using the RM was equally high for macroreentrant (79%) and focal ATs (82%, P = 1.000). Of the 33 LAT maps in disagreement with the observers, adjusting the window-of-interest (WOI) after reviewing the RMs achieved diagnostic agreement of 91% (30 ATs).
conclusionRMs allow us to have precise understanding of the atrial propagation on high-density CARTO maps for both focal and macroreentrant ATs, which is particularly useful for cases with difficult-to-interpret LAT maps.
