Totally thoracoscopic beating-heart redo mitral valve surgery with hyperkalemic bradycardia: technique and early results.
Article in Journal of thoracic disease, 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: Although beating-heart redo mitral valve (MV) surgery has been previously documented in several reports, experience with totally thoracoscopic reoperations remains limited. The present study was undertaken to describe our institutional experience with totally thoracoscopic beating-heart redo MV surgery employing a systemic hyperkalemic bradycardia technique during cardiopulmonary bypass (CPB) and to assess its early clinical outcomes. Methods: A comprehensive retrospective review of the database was undertaken from September 2020 to January 2026. Patients undergoing totally thoracoscopic redo MV surgery via right minithoracotomy (MINI group) were compared with those managed by conventional resternotomy (CON group). Perioperative variables and early clinical outcomes were subjected to comparative statistical analysis. Results: A total of 111 patients were included (43 MINI, 68 CON). The MINI group had shorter CPB time (104.7±18.7 Conclusions: Totally thoracoscopic beating-heart redo mitral surgery employing hyperkalemic bradycardia reduces blood transfusion requirements, lowers hospital costs, and shortens length of stay compared with the conventional method. This technique appears safe and effective, and may be appropriately considered for carefully selected patients requiring redo MV surgery.
