Article Abstract
Background: Since being declared as a pandemic on March 11, 2020, coronavirus disease 2019 (COVID-19) has profoundly influenced heart and lung transplant programs, impacting donor availability, patient management, and healthcare resources. This study offers a citation-based review of the research output on this subject, seeking to understand how the transplant community has responded to these challenges. Through a review of literature from the beginning of the pandemic to early 2023, we evaluate the shifts in academic emphasis and the emerging trends in heart and lung transplantation during the COVID-19 period.
Aim: To assess the impact of COVID-19 on heart and lung transplantation research, highlighting key themes, contributions, and trends in the literature during the pandemic.
Methods: We conducted an extensive search of the Web of Science database on February 9, 2023. We employed the terms "transplant" and "transplantation", as well as organ-specific terms like "heart", "cardiac", and "lung", combined with COVID-19-related terms such as "COVID-19", "coronavirus", and "SARS-CoV-2". The search encompassed publications from March 11, 2020 to February 9, 2023. Data on authors, journals, countries, institutions, and publication types (articles, reviews, conference papers, letters, notes, editorials, brief surveys, book chapters, and errata) were analyzed. The data was visualized and processed with VOSviewer 1.6.18 and Excel.
Results: We included 847 research items. There were 392 articles (46.3%) and 88 reviews (10.3%). The studies included were referenced 7757 times, with an average of 9.17 citations per article. The majority of the publications ( = 317) were conducted by institutes from the United States with highest citations ( = 4948) on this subject, followed by Germany, Italy, and France. The majority of papers ( = 101) were published in the .
Conclusion: To the fullest extent of our knowledge, this is the first bibliometric study of COVID-19's impact on heart and lung transplantation to offer a visual analysis of the literature in order to predict future frontiers and provide an overview of current research hotspots.

In lung CT imaging, motion artifacts caused by cardiac motion and respiration are common. Recently, CLEAR Motion, a deep learning-based reconstruction method that applies motion correction technology, has been developed. This study aims to quantitatively evaluate the clinical usefulness of CLEAR Motion.

Background: Diabetic patients with ST-segment elevation myocardial infarction (STEMI) are at an increased risk of cardiovascular events as compared to non-diabetic patients. This analysis investigated outcomes of diabetic patients presenting with multivessel disease (MVD) and STEMI in a contemporary trial and the relevance of an immediate versus staged multivessel PCI strategy in this high-risk population.
Methods: Patients enrolled in the MULTISTARS AMI trial were stratified according to the presence/absence of diabetes.

Background: Postoperative cognitive dysfunction (POCD) occurs in 20% to 80% of patients following cardiac surgical interventions. The incidence of delirium is from 20% to 50%. Impaired cerebral autoregulation (CA) during cardiopulmonary bypass (CPB) contributes to these issues.

Objectives: Elevated intracranial pressure (ICP) is a complication of severe traumatic brain injury (TBI) that carries a risk of secondary brain injury. This study investigated the association between ICP burden and brain injury patterns on MRI in children with severe TBI.
Design, Setting, And Patients: Secondary analysis of the Approaches and Decisions in Acute Pediatric TBI (ADAPT) study, which included children with severe TBI (Glasgow Coma Scale score < 9) who received a clinical MRI within 30 days of injury.

Background: Solid organ transplant (SOT) recipients are not only at increased risk of morbidity and mortality due to acute COVID-19 but may also experience poor long-term outcomes due to post-acute COVID-19 syndromes, including long COVID.
Methods: This retrospective, registry-based chart review evaluated graft failure and mortality among SOT recipients diagnosed with COVID-19 at a large, urban transplant center in Houston, Texas, USA. Patient populations were analyzed separately according to their long COVID status at the time of transplant to preserve the temporal relationship between the exposure (long COVID) and the outcome (graft failure or mortality).
