Design outcomes

Primary

MeasureTime frame
Assessment of changes in hemodynamic parameters when heart is repositioned for coronary arterial grafting of each territory using the Pulse Contour Analysis (Flotrac based) method & 3D TEE based volumetric analysis method and comparison of the two methods Timepoint: All the time points are within the surgical period in operation room 1.Before start of grafting and after induction of general anaesthesia 2.Repositioned for Left Anterior descending artery territory 3.Repositioned for Obtuse Marginal territory 4.Repositioned for posterior descending artery territory 5.After completion of grafting and heart positioned in normal state—

Secondary

MeasureTime frame
To assess change in HR, SBP, DBP, MAP, CVP during positioning of heart for arterial grafting of each territory.Timepoint: All time points are during the surgery itself. 1.Before start of grafting and after induction of general anaesthesia 2.Repositioned for Left Anterior descending artery territory 3.Repositioned for Obtuse Marginal territory 4.Repositioned for posterior descending artery territory 5.After completion of grafting and heart positioned in normal state—
