OBJECTIVETo introduce the experience in coronary artery bypass grafting (CABG) combined with concomitant valve operation.

METHODSFrom 1998 to 2002, forty-five patients (38 men and 7 women) with coronary artery lesion and valve diseases underwent myocardial revascularization combined with concomitant valve operation. The mean age of the patients was 59 years (42 to 75 years). Heart function was Class II (NYHA) in 7 patients, Class III in 30, Class IV in 8. The value of ejection fraction was 0.32 to 0.50. Thirty patients had mitral valve lesion, 7 aortic lesion, and 8 both lesions. Seventeen patients had single-vessel diseases, 20 double-vessel diseases, 8 triple -vessel diseases, and 8 left main artery lesion. After cardiac arrest by cold blood cardioplegia under moderate cardiopulmonary bypass (CPB), distal anastomosis of the saphenous vein (SV) to the target vessels were firstly performed and followed by valve replacement (32 patients) or plasty (2). The left internal mammary artery (LIMA) was grafted to the left anterior descending artery (LAD) before aortic unclamping. Proximal anastomosis of the SV to the aorta was finally finished on beating heart. The mean bypass time was 173.5 min and the mean duration of aortic cross-clamping time was 112.6 min.

RESULTSNo mortality occurred during hospitalization and all patients were discharged 9.2 days after operation. Cardiac function of all patients was improved to Class I-II and no patient died during follow-up.

CONCLUSIONSCABG combined with valve surgery can be safely performed with good results.
