Key result
Bibliometric analysis reveals consistent growth in TEE research led by the US.
Why the study?
Transesophageal echocardiography has gained prominence in clinical practice, but an overview of research trends and emerging topics was needed.
This bibliometric analysis demonstrates the growing prominence of transesophageal echocardiography in clinical research, highlighting the United States as a leading contributor and identifying PFO treatment as a recent hot topic.
OBJECTIVE: Heart disease poses a significant global health challenge. Transesophageal echocardiography (TEE) has gained prominence in clinical practice because of advancements in visual medicine. The present bibliometric analysis provides an overview of TEE research, identifies trends, and highlights emerging topics. METHODS: A comprehensive search of TEE-related literature from the establishment of the Web of Science Core Collection (WOSCC) until 2022 was conducted. Utilizing the CiteSpace software, we performed an in-depth analysis of the literature data encompassing disciplines, publication years, countries, institutions, authors, journals, cited references, and keywords. RESULTS: A total of 17 032 TEE-related articles were included in this study. The most active disciplines in TEE research were Cardiac & Cardiovascular Systems, Anesthesiology, and Respiratory System. The number of publications displayed a consistent upward trajectory over the years. Notably, research contributions predominantly originated from developed countries, mainly Europe and North America, with the United States, Germany, Italy, and Japan leading the way. Analysis of institutions, authors, and journals revealed the United States' significant role in TEE research. Furthermore, the analysis of cited references and keywords identified the treatment of patent foramen ovale and its association with stroke as emerging hot topics in recent years. CONCLUSIONS: This study highlights that TEE remains a research hotspot, with the United States at the forefront. Future research should investigate the relationship between heart disease and brain function.
