Long-term mortality following robotic mitral valve repair.
Article in JTCVS structural and endovascular, 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
Objective: To compare long-term mortality between robotic and conventional mitral valve repair (MVr) for degenerative mitral regurgitation (DMR). Methods: A retrospective analysis of Medicare data from 2012-2024 for patients who underwent surgical MVr for DMR was conducted. Patients with prior cardiac surgery were excluded. Two groups were created: robotic MVr and conventional MVr, which included both sternotomy and thoracotomy approaches. The primary outcome was 5-year mortality. Robotic and conventional cases were 1:2 propensity score matched for outcome assessment. Results: A total of 1502 cases of robotic MVr and 12,182 cases of conventional MVr were identified. The robotic approach represented a growing proportion of surgical MVr. Compared to patients who underwent conventional MVr, patients who underwent robotic MVr were younger and had a lower comorbid disease burden ( Conclusions: Robotic MVr offered comparable long-term survival to conventional MVr in Medicare patients. These results support the use of robotic MVr for DMR for appropriately selected patients and skilled surgeons.
