Worldwide research trends on left ventricular assist devices for heart failure: a bibliometric analysis.
Review in Journal of cardiothoracic surgery, 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
backgroundWith advancements in medicine, left ventricular assist devices (LVADs) have emerged as a viable treatment option for heart failure (HF). Numerous experts have examined the primary challenges and societal implications associated with the use of LVADs in managing heart failure. This study seeks to analyze the global literature on LVADs for the treatment of heart failure published between 2004 and 2024, aiming to identify key research hotspots and emerging trends within this field.
methodsThis study conducted a bibliometric review of literature on LVADs for the treatment of heart failure from 2004 to 2024. Visual analysis was conducted on a total of 871 publications using CiteSpace (version 5.8) and VOSviewer (version 1.6.15.0).
resultsOver the past two decades, research on LVADs has developed continuously, accompanied by a stable annual growth in publications. The United States contributed the largest number of publications (187 articles), followed by other highly active countries and research networks. Columbia University was the most productive institution, while Rogers Joseph G and Farra David J were the most prolific authors. Keyword analysis indicated that "left ventricular assist device" was the core terminology, reflecting the central focus of global research. Further thematic analysis revealed principal research themes including device optimization, clinical outcomes and complication management, patient selection and prognostic evaluation, and long-term quality of life in supported patients.
conclusionsThe field of left ventricular adjuvant therapy for heart failure has undergone steady development for 20 years and has now begun to show results. The results of this bibliometric analysis provide ideas and references for future researchers to further promote the development of this field.
