Incidence and Predictors of Valve Pop-up During Navitor Valve Implantation.
Article in Circulation reports, 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
Background: The Navitor valve shows excellent valve function and high deliverability. However, valve pop-up during valve implantation remains a concern. Methods and Results: We defined pop-up as an upward valve dislocation ≥3 mm after implantation. Pop-up occurred in 13 (19%) of 67 patients, with 2 (3.0%) patients requiring a second valve. The depth ratio between non- and left-coronary cusp side at the 80% release and aortic valve calcification score were identified as predictors of valve pop-up. Conclusions: Pop-up of the Navitor valve occurred in 19% of patients. Inconsistent valve depth and severe leaflet calcification were predictors of valve pop-up.
