Ultracompact magnetically levitated BiVAD for low-body-weight pediatrics

End-stage heart failure has become a major global health challenge.1 The global scarcity of pediatric donor organs results in an insufficient number of annual heart transplantations to meet the clinical demands of children with end-stage heart failure.2 While ventricular assist devices (VADs) serve as an effective alternative to heart transplantation, only 448 pediatric VAD implantations were reported in the United States from 2012 to 2021, according to the Pediatric Interagency Registry for Mechanical Circulatory Support (PediMACS).
