Transcatheter repair for papillary muscle rupture Post-AMI.
Article in BMC cardiovascular disorders, 2025. 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
backgroundRupture of the papillary muscle is a serious complication of acute myocardial infarction (AMI), usually leading to mitral valve dysfunction and severe regurgitation, which in turn causes acute heart failure, posing a significant threat to the patient's life. CASE PRESENTATION: This case report aims to explore the feasibility and effectiveness of the DragonFly™ system in patients with papillary muscle rupture following AMI. We describe a 71-year-old male patient who was admitted due to chest tightness and chest pain, and upon examination, severe mitral regurgitation and papillary muscle rupture were found. Although the patient had missed the opportunity for emergency reperfusion, due to significant symptoms and heart failure, the cardiac team decided to perform a transcatheter edge-to-edge repair (TEER) of the mitral valve. During the procedure, guided by ultrasound and imaging, two valve clips were successfully implanted, significantly improving the mitral regurgitation. Postoperative assessment showed a reduction in regurgitation from 4 + to 1+, and the patient was discharged smoothly.
conclusionsPatients with AMI accompanied by papillary muscle rupture have poor condition. CLINICAL TRIAL NUMBER: Not applicable.
