Spatiotemporal tissue temperature during cryoablation using different balloons.
Article in Heart rhythm O2, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Differences in tissue temperature trends and distribution between two commercially available balloons during cryoablation remain unclear. Objective: We sought to evaluate spatiotemporal tissue temperatures during cryoablation using different cryoballoons. Methods: An in vitro pulmonary vein model was constructed from porcine myocardial tissue to simulate pulmonary vein anatomy and venous flow. A multitemperature sensor sheet was placed behind the muscles. After confirming pulmonary vein occlusion, cryoablation was performed using the Arctic Front Advance Pro (AFA-Pro) and POLARx FIT (28 and 31 mm) to evaluate the time course of spatial tissue temperatures. Results: POLARx FIT 28 mm showed the lowest force for pulmonary vein (5.5 ± 1.0 N for AFA-Pro, 4.0 ± 0.8 N for POLARx FIT 28 mm, and 4.1 ± 0.7 N for POLARx FIT 31 mm, respectively ( Conclusion: Among commercially available balloons, the POLARx FIT of 28 mm achieved the greatest tissue temperature drop, whereas the POLARx FIT of 31 mm created the broadest cooled tissue area.
