After one year of follow-up, none of the patients in both groups had major cardiac events or CCU admission. Postoperative routine trans-thoracic echo (TTE) follow-up was done upon discharge, as well as after 3 months, 6 months, and 1 year for all patients in both groups. Regional wall motion abnormalities were noted in 15 patients (37.5%) of group I versus 17 patients (42.5%) of group II (P=0.648), who all undergone stress ECG, of whom 9 patients (22.5%) in group I versus 11 patients (27.5%) in group II showed positive results (P=0.606), and qualified for diagnostic coronary angiography, which confirmed the need for reoperation for myocardial ischemia/infarction within the first year of follow up post-operatively in 4 patients (10%) of group I versus 8 patients (20%) of group II (P=0.210). All these follow up outcomes showed no significant difference between both groups (Table 7).
