At the time of CS either Impella RP or vasoactive treatment (norepinephrine and milrinone) was initiated. Echocardiography and conductance measures were obtained at baseline, when CS was present, and 30, 90, and 180\u2009minutes after induction of CS. Of 20 animals, 14 completed the protocol and were treated with either vasoactive treatment (n=7) or Impella RP (n=7); 6 animals died (3 in each group). In the RV there was a significantly higher LS with the vasoactive treatment compared with Impella RP (\u22127.6% [4.5] to \u22126.0% [5.2] vs \u22124.5% [6.6] to \u201314.2% [10.6];\n                      <jats:italic>P<\/jats:italic>\n                      &lt;0.006). Left ventricular LS improved with both treatments compared with shock, but with a larger effect (\u22129.4% [3.2] to \u221217.9% [3.6]) on LS with vasoactive treatment than Impella RP (\u22129.8% [3.1] to \u221212.3% [4.6];\n                      <jats:italic>P<\/jats:italic>\n                      &lt;0.001).
