Echocardiographic data of 13 swine that were resuscitated with either the Impella ECP or veno-arterial ECMO at baseline (BL) and at 30 (PR 30), 180 (PR 180), 300 (PR 300) and 360 (PR 360) minutes following the return of spontaneous circulation. The data are presented as the means ± standard deviations.
E/A early mitral inflow/mitral inflow at atrial contraction, E/e’ early mitral inflow/mitral annular early diastolic velocity, LV-EF left ventricular ejection fraction, LV-GLS left ventricular global longitudinal strain, MV DT mitral valve deceleration time, RVD₁ right ventricular basal diameter, RV-GLS right ventricular global longitudinal strain, TASV tricuspid annular systolic velocity.
p > 0.05 for all comparisons.
