Abstract:
BACKGROUND:Heart valve surgery combined with coronary artery bypass grafting has been gradual y used for treatment of coronary heart disease combined with cardiac valve disease.
OBJECTIVE:To retrospectively summarize the experience of combined coronary artery bypass grafting and valvular procedure.
METHODS:Total y 51 patients who underwent combined heart valve surgery and coronary artery bypass grafting were retrospectively analyzed, including 10 cases with aortic valve replacement, 14 cases with mitral valve replacement, eight cases with mitral valve replacement combined with tricuspid annuloplasty, four cases with aortic valve and mitral valve replacement, three cases with aortic valve and mitral valve replacement combined with tricuspid annuloplasty, seven cases with mitral valvuloplasty, and five cases with mitral valvuloplasty combined with tricuspid annuloplasty.
RESULTS AND CONCLUSION:Biovalve replacement was performed in nine patients, mechanical valves replacement in 31 cases, mitral valvuloplasty in 11 cases and tricuspid annuloplasty in 16 cases. There were total y 109 bypass graft vessels, and the average number of coronary artery bypass grafts was (1.92±0.73) branches. Four cases died within 30 days postoperatively, and 47 patients were successful y discharged from the hospital. Forty-five of 47 discharging patients were fol owed for 3-48 months. One case died of cerebral infarction within 6 months postoperatively, and another case died of cardiac dysfunction over 1 year after operation. The heart function of 45 survival patients was significantly improved. The comprehensive analysis showed that improving the heart function preoperatively, strengthening myocardial protection, shortening operation and myocardial ischemia time, and complete revascularization are the key factors for successful operation.
