Abstract:Background: The utilization of a combination of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and Impella, ECPELLA, has become widespread among patients with cardiogenic shock. The utilization of VA-ECMO in the presence of aortic regurgitation (AR) can result in significant left ventricular (LV) distention. Additionally, the implantation of Impella via the aortic valve frequently induces AR clinically. We established a simulation model and evaluated the impact of AR on hemodynamics under ECPELLA.… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
