Impella 5.5 Use in the Setting of Severe Aortic Insufficiency: A Relative Contraindication.
Article in Annals of thoracic surgery short reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Moderate or severe aortic insufficiency is a contraindication to transvalvular Impella left ventricular assist device (Abiomed) use out of concern for worsening valvular insufficiency and recirculation. This report describes the case of a 75-year-old man with severe eccentric aortic insufficiency and systemic hypoperfusion who was supported with a transvalvular Impella 5.5 device for 6 days as preoperative rehabilitation before aortic valve replacement. The Impella device provided adequate systemic tissue perfusion, and left ventricular function remained without signs of volume overload and recirculation. Moderate or severe aortic insufficiency may not be an absolute contraindication to transvalvular Impella use, although this is case dependent.
