OverviewAI-generated summary

Lawrence Greiten's research focuses on pediatric cardiothoracic surgery, with a particular emphasis on congenital heart defects and the management of complex post-operative complications. His work includes developing consensus recommendations for managing conditions such as post-operative chylothorax in children with congenital heart disease. Greiten also investigates the outcomes and contemporary applications of mechanical circulatory support devices in pediatric patients, contributing to registries like the ACTION VAD registry. His research extends to evaluating the safety and effectiveness of specific cardiac valve replacements in young patients and exploring novel surgical approaches for vascular anomalies.

Greiten's scholarship is further informed by an interest in decision-making processes within high-stakes medical environments, as evidenced by his work on cognitive biases in joint pediatric cardiology and cardiothoracic surgery conferences. His publication record also includes studies on ventricular dysfunction following surgical repair of congenital heart defects. With an h-index of 4 and 44 total publications, Greiten actively collaborates with colleagues at the University of Arkansas for Medical Sciences, including Brian Reemtsen (25 shared publications), Thomas Heye (11 shared publications), Markus S. Renno (9 shared publications), and Elijah H. Bolin (7 shared publications).

Research Interests

Throughout his training and early career, Dr. Greiten has demonstrated a dedicated and focused research path which enhances the quality of care he provides to his patients as a congenital pediatric cardiac surgeon. Furthermore, Dr. Greiten has quickly become an active and funded investigator at UAMS/Arkansas Children’s Hospital. Dr. Greiten’s clinical research interests include: clinical outcomes of palliative and definitive repairs of congenital cardiac malformations, neurodevelopmental outcomes after cardiac surgery, single ventricle pathophysiology, and cardiac transplantation. Dr. Greiten has also published several surgical education projects and has an interest in developing simulation platforms pertaining to extracorporeal membrane oxygenation, minimally invasive cardiac and endovascular techniques. Throughout his early career, Dr. Greiten’s research has been supported with nearly one million dollars in funding. Lastly, during his surgical training Dr. Greiten successfully completed a Master’s in Biomedical Sciences, Clinical and Translational Science where he published several papers on thromboprophylaxis and became an internationally renowned expert shifting the paradigm of novel anticoagulation strategies. In his career, Dr. Greiten has been the primary or major contributor of multiple publications, several book chapters, as well as various abstracts and surgical videos. In the process Dr. Greiten has received numerous research awards at various national conferences and institutions.
