Objective:To summarize the clinical experience in CABG

so as to look for the optimal perioperative management procedure and improve the operative outcome.Methods:The data of coronary artery bypass were analyzed in 9 patients with coronary heart disease.Results:CABG of all patients was performed on hypothermia cardiopulmonary bypass (CBP).Myocardial preservation was carried out by cold blood cardioplegia with potassium.The average length of time of CPB was 178(70～222) minutes

and that of aortic cross clamp was 111(70～150) minutes.A total of 23 cases of coronary artery bypass were performed using 8 left internal mammary arteries and 15 long saphenous veins.One patient with rheumatic valvular disease associated with coronary heart disease received coronary artery bypass grafts and double valve replacement at the same operation.One patient died of respiratory function failure and the rest were discharged with angina disappearing.Conclusion:The success of coronary artery bypass lies in obtaining of grafts

identifying adequate target vessel

complete revascularizing ischemic myocardium and refining blood vessel anastomosis.Good myocardial protection and perioperative management are also important.
