Knowledge mapping and research trends in degenerative mitral regurgitation: a bibliometric analysis from 2004 to 2024.
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: Degenerative mitral regurgitation (DMR) is a cardiovascular condition marked by progressive degeneration of the mitral valve, leading to complications such as heart failure and atrial fibrillation. Despite advancements, research trends and knowledge gaps remain inadequately addressed. Therefore, this study aimed to perform a comprehensive bibliometric analysis of DMR-related research to identify publication trends, influential contributors, and emerging research themes. Methods: A bibliometric analysis was conducted on articles related to DMR published from 2004 to 2024, retrieved from the Web of Science Core Collection (WoSCC) database. Data were analyzed using Microsoft Excel, R-bibliometrix, VOSviewer, and CiteSpace to evaluate publication trends, international collaborations, key contributors, and emerging research themes. Results: A total of 2,349 publications were identified, with an annual growth rate of 4.07%, involving 12,474 contributors from 79 countries. The USA led with 726 publications and 37,386 citations. Leading institutions included Mayo Clinic and Harvard University. The top journals were the Conclusions: This bibliometric analysis highlights significant advancements in DMR research, particularly in surgical techniques and imaging modalities, and provides a foundation for future studies aimed at improving patient outcomes.
