Cardiac ochronosis with severe aortic and mitral valve stenosis: a challenge case.
Article in Journal of cardiothoracic 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
Ochronosis is a hereditary disorder characterized by black pigmentation in tissues. Cardiac ochronosis is most commonly associated with aortic stenosis, while mitral stenosis is a less frequently observed involvement. In this case presentation, we will discuss ochronosis diagnosed during open heart surgery in a patient who had not been previously diagnosed. Our patient underwent surgery for aortic valve and mitral valve replacement. The aortic root, mitral valve, and aortic-mitral curtain were found to be calcified, and a mandatory Commando procedure was performed. The coronary buttons could not be mobilized, and the Cabrol procedure was applied. In cases of ochronosis, it is a fact that decalcification can lead to significant complications, and the involvement of the aortic-mitral curtain must also be considered by the surgeon.
