Intraoperative Indocyanine Green Near-Infrared Angiography for Redo Valve Replacement.
Article in The Thoracic and cardiovascular surgeon reports, 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
Background: Redo aortic interventions after failed transcatheter aortic valve replacement (TAVR) are challenging, particularly with low coronary heights and dense frame ingrowth. Case Description: An 83-year-old woman with prior TAVR developed severe prosthetic stenosis. Surgical Resection of Prosthetic Valve Leaflets Under Direct Vision (SURPLUS) with implantation of a balloon-expandable aortic valve and intraoperative low-dose indocyanine green (ICG) near-infrared (NIR) angiography was performed. Real-time NIR imaging confirmed symmetric coronary opacification. The valve was well seated with improved ejection fraction (60-65%), and recovery was uneventful. Conclusion: SURPLUS with ICG-NIR angiography ensured coronary patency and safe hemodynamic restoration.
