To assess the hemodynamic effects of adjunct intra-aortic balloon pumping during veno-arterial ECMO.
Conducted invasive pressure-volume (PV) loop analyses on a patient
Measured left ventricular (LV) and right ventricular (RV) afterload
Assessed preload in both ventricles during varying flow conditions of VA-ECMO
IABP support significantly reduced LV afterload during high-flow VA-ECMO
IABP support also reduced RV afterload during the same conditions
Both ventricles experienced decreased preload at low VA-ECMO flow
Abstract
In our patient, invasive PV loop analyses showed that IABP support reduced LV and RV afterload during high-flow V-A ECMO and decreased preload of both ventricles at low VA-ECMO flow.
