Design outcomes

Primary

MeasureTime frame
1.Cardiac output by thermodilution method 2.Cardiac output by trans-esophageal echocardiography at aortic valve level Timepoint: T1: Clinical steady state 15minutes after induction of anaesthesia T2: After sternal closure—

Secondary

MeasureTime frame
1.Hemodynamic monitoring including heart rate, systolic, diastolic and mean arterial pressures and pulmonary artery pressure.Timepoint: Every 60minutes throughout the operative period;2.Complications associated with each techniqueTimepoint: intra-operative and post-operative till patient is discharged from ICU;Clinical outcome assessment: a)Total inotropic score b)Number of shock if needed c)Arrhythmia if noted d)Morbidity and mortality after risk adjustment Timepoint: Intra-operative and post-operative till patient is discharged from ICU—
