Impella-Assisted Coronary Bypass With Massive Stroke From Aortic Side Arm Graft Thrombosis.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2026. 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
A 59-year-old man with an ejection fraction of 20% underwent off-pump coronary artery bypass grafting (CABG) with an Impella 5.5 placed through a side arm graft to the ascending aorta tunnelled to the left neck. The Impella was removed on postoperative day 2 at the bedside with local anaesthesia, and the graft ligated at the level of the skin. The patient was discharged on postoperative day 6 with no complications. He returned on postoperative day 184 with a large left cerebral stroke, with computed tomography angiography showing thrombus in the remnant graft extending into the ascending aorta, wrapping around the aortic arch, and going into the left common carotid artery. He required hemicraniectomy and prolonged rehabilitation. This report serves to raise awareness of this complication and provides a discussion on the use of Impella assistance for CABG.
