- Primary Outcome Measures
Name Time Method our primary objective will be to compare the Cardiac output, Stroke Volume Variation, Ventricular Ejection time and Systemic Vascular Resistance measured using bioreactance method with that of 3D TEE method.Timepoint: Baseline, Before and After passive leg rise, Before and After Sternotomy.
- Secondary Outcome Measures
