Stepwise Annular Reconstruction for Redo Double-Valve Surgery in Severe Mitral Annular Calcification.
Article in JACC. Case 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
backgroundRedo aortic and mitral valve surgery with severe mitral annular calcification (MAC) and intervalvular fibrous body destruction is highly challenging; the Commando procedure is often a last resort. CASE SUMMARY: A 59-year-old man with prior mechanical aortic and mitral valve replacements presented with hemolytic anemia due to a mitral paravalvular leak. Imaging showed severe MAC and tricuspid regurgitation. Intraoperatively, massive calcification and insufficient native tissue precluded standard anchoring for implantation of the new mechanical valves. In addition to the standard Commando procedure, a bovine pericardial patch was used reconstruct a neo-mitral annulus. Recovery was uneventful. DISCUSSION: Bovine pericardial patches offer structural support when native tissue is inadequate, facilitating safe and durable outcomes in complex redo valve procedures. TAKE-HOME MESSAGES: This case illustrates a viable surgical strategy for high-risk redo double-valve procedures. Bovine patch reconstruction enabled stable valve implantation and functional restoration in the setting of extensive MAC.
