Remaining of contrast dye ice cap during PVI by cryoballoon ablation; a case report.
Article in Journal of cardiothoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Pulmonary vein isolation (PVI) with cryoballoon (CB) ablation technology is widely used to treat drug-resistant atrial fibrillation (AF). During CB ablation, there is a possibility of forming an ice cap of contrast-color on top of the balloon. If automatic balloon deflate occurs before the ice cap dissolves, embolization to the systemic circulation is possible. This case report describes the remaining of a contrast-colored ice cap to the systemic circulation in the left superior pulmonary vein (LSPV) and the remaining contrast-colored ice cap throughout the balloon deflate and its gradual melting a few seconds after the balloon deflate in the right superior pulmonary vein (RSPV). Additionally, a strategy for its prevention is presented.
