Core Tip

Core Tip: The coronavirus disease 2019 (COVID-19) pandemic, which started on March 11, 2020, has had a huge impact on heart and lung transplant programs. We performed an extensive search in the Web of Science database, utilizing keywords associated with transplantation and COVID-19, encompassing publications from March 11, 2020, to February 9, 2023. We analyzed data on authors, journals, countries, institutions, and different types of publications using VOSviewer 1.6.18 and Excel for visualization and data manipulation. The study encompassed a total of 847 research items, consisting of a substantial number of articles and reviews. The average citation rate per article was 9.17. The majority of publications were from United States institutions, which also had the highest citation count, followed by Germany, Italy, and France. This bibliometric study is the first to give a full picture of how COVID-19 has affected heart and lung transplants, showing where more research is needed and where it should go in the future.
