Overview

US leads LVAD publication output; leaves open whether global disparities shape device optimization and patient selection.

Key Points

  • This analysis aims to explore global literature trends on left ventricular assist devices for heart failure from 2004 to 2024.
  • Conducted a bibliometric review of LVAD literature published from 2004 to 2024, analyzing 871 publications.
  • Utilized CiteSpace (version 5.8) and VOSviewer (version 1.6.15.0) for visual analysis.
  • Identified key research themes such as device optimization, clinical outcomes, and patient selection.
  • The United States produced the most publications (187 articles) in this area.
  • Key themes include device optimization, clinical outcomes, and patient selection for LVAD use.
  • The research has shown a consistent annual growth in publications over two decades.

Cite This Study

Sun et al. (2026) conducted a review in heart failure (n=871). Left ventricular assist devices (LVADs) was evaluated on Bibliometric trends and research hotspots. A bibliometric analysis of 871 publications from 2004 to 2024 revealed that device optimization, clinical outcomes, patient selection, and quality of life are principal research themes for LVADs.
