•1. Adult patients with coronary artery disease undergoing elective coronary artery bypass grafting (CABG) without repair or replacement of other valves.
•2. Patient operated for CABG first time.

•1. Patients below 18 years of age and > 70 years of age
•2. Inadequate imaging of LV to interpret the results on CMR, intraoperative 2D TEE, or RT-3D TEE
