Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
