Application Of On-pump Coronary Artery Bypass Grafting In The Treatment Of 42 Patients With Severe Coronary Artery Disease

Objective:To review 42 cases of on-pump coronary artery bypass grafting(OP-CAB) in patients with left ventricular ejection fraction(LVEF)less than 0.30. Methods:42 cases of selected off pump coronary artery bypass grafting from patients with left ventricular ejection fraction(LVEF)less than 0.3, whose mean left ventricular ejection fraction was 0.26±0.03,36 of male,6 of femal. Preoperative echocardiographic examinations revealed a mean of left ventricular dias-tolic dimension(LVDD) (61.3±4.2)mm. The preoperative EF,LVDD,LVSD and postoperative EF,LVDD,LVSD after two week and three months were registered. Results:42 cases of OPCAB surgery were performed. The mean number of distal anastomotic stoma was 3.5±1.3, Intra-aortic balloon pump was used in 6, all balloons were inserted at operations.Two patients died in hospital. Conclusion:OPCAB has a good feasibility and a short-term favorite effect in patients with low ejection fraction, could obviously decrease the risk of the surgery and anaesthesia.
