Impella-Supported Off-Pump Coronary Artery Bypass Grafting (CABG) in a Patient With Severe Mitral Regurgitation: A Case Report.
Article in Cureus, 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
Perioperative cardiogenic shock can be fatal, and assisted circulation with an Impella percutaneous ventricular support pump catheter (Abiomed, Danvers, MA, USA) is useful in patients with severely compromised cardiac function. However, we report a case in which an Impella implanted preoperatively deepened its position during off-pump coronary artery bypass grafting decannulation. This change in position caused the Impella to interfere with the posterior mitral valve leaflet and led to severe mitral regurgitation and difficulty with intraoperative circulatory control. In patients without significant left ventricular enlargement, the heart team should discuss the risk of interference with the mitral valve and inhalation failure during decannulation. In such cases, other forms of assisted circulation, such as intra-aortic balloon pumping or cardiopulmonary bypass, should be considered.
