Assessment of hemodynamic parameters by PiCCO and PAC in patients treated with the Impella CP

In 28 patients supported by an Impella pump (Impella CP, Abiomed Inc.^®, Danvers, MA), hemodynamic measurements by PiCCO (PULSION Medical Systems SE^®, Feldkirchen, Germany) and pulmonary artery catheter (PAC or Swan-Ganz Catheter; Edwards Lifescience^®, Unterschleissheim, Germany) were compared. There was a significant positive correlation of cardiac output (CO; r ² = 0.917, p < 0.001), systemic vascular resistance index (SVRI; r ² = 0.904, p < 0.001), stroke volume index (SI; r ² = 0.909, p < 0.001) and left ventricular work index (LCWI; r ² = 0.689, p < 0.001) in PiCCO and PAC measurements under Impella CP support. We conclude, that in patients with left-ventricular Impella support, hemodynamics may be assessentd by PiCCO or PAC.
