Patients undergoing coronary artery bypass grafting up tp 30% will develop postoperative right ventricle dysfunction. Its imperative for the physician to fully understand the severity of this complication in order to perform an early diagnosis and carry out the appropriate treatment. Aim: Investigate the correlation between echocardiographic measurements and hemodynamic changes at different time points in patients undergoing coronary artery bypass graft surgery Hypothesis: 1. Weak correlation between echocardiographic measurements and hemodynamic changes during coronary artery bypass graft surgery 2. Echocardiographic measurements would change across different time points during surgery independent of hemodynamic values.

Change of right ventricular function during CABG assessed by right heart strain (%)
Assessing the change of RV function during CABG surgery using right heart strain as a percentage of change between RV shortening and RV end diastolic length.
Time frame: during CABG surgery
Change of right ventricular function during CABG assessed by stroke volume index (mL/m2)
Assessing the change of RV function during CABG surgery using stroke volume index. Stroke volume index measurement as millilitres per square meter (ml/m2)
Time frame: during CABG surgery
Change in cardiac output measured with Swan-Ganz during CABG
Cardiac output (L/min) measured with the thermodilution technique
Time frame: during CABG surgery
