BACKGROUND: Combined heart and lung transplantation represents a critical therapeutic approach for addressing end-stage cardiac and pulmonary diseases. This study seeks to conduct a comprehensive analysis of the global literature on combined heart and lung transplantation from 1980 to 2024, with the objective of identifying key research trends and emerging areas of interest within this domain.
METHOD: A systematic search and compilation of bibliometric data related to combined heart and lung transplantation, published between 1980 and 2024, was conducted using the Web of Science Core Collection. Subsequent bibliometric and knowledge mapping analyses were performed utilizing CiteSpace 6.1.R6 (Basic) and VOSviewer (1.6.18).
RESULTS: A total of 1746 articles were retrieved, indicating a stable upward trend in the field of combined heart and lung transplantation, particularly in the number of published papers over the past two decades. The United States leads in the number of published articles (1066), followed by Germany (155) and the United Kingdom (140). In terms of keyword analysis, the most frequently used keywords are "lung transplantation" (226), "transplantation" (172), and "survival" (146). An analysis of cited keywords reveals that "severe combined immunodeficiency" was the most prominent keyword prior to 2000, whereas "Outcome" has emerged as the most significant keyword since 2000.
CONCLUSION: Over the past four decades, the field of combined heart and lung transplantation has undergone consistent and rapid advancement. The findings from this bibliometric analysis offer valuable insights and serve as a reference point for future research endeavors and for stakeholders engaged in this area.
