Preeclampsia, foetal growth limitation, abruption, and stillbirth are all made more likely when the uterine artery PI, a marker of uteroplacental perfusion, is elevated. It is termed elevated if the Uterine Artery PI exceeds the 90th percentile. WebThe PI is inversely related to the amount of assistance provided by the LVAD. A high PI indicates more native ventricular filling and less pump support. A lower PI value indicates less ventricular filling due to less circulating blood volume or an obstruction in the LVAD, meaning the patient requires more pump support. rotary slide
