In a randomized controlled trial (MOMENTUM 3), the HeartMate 3 (HM3) fully magnetically levitated centrifugal-flow left ventricular assist device (LVAD) demonstrated superiority over the HeartMate II (HMII) axial-flow LVAD. These findings were driven by hemocompatibility-related outcomes, but infection-related outcomes were not altered by device choice. In this trial-level analysis, we analyzed the clinical patterns of infection-related outcomes over 2 years of support.
