To improve the effect and reduce the mortality of the simultaneous coronary artery bypass grafting (CABG) with other cardiovascular surgical procedures, from Nov, 1984 to July, 1996, 51 patients underwent such operation. Among them 45 patients had valvular heart diseases, 4 postinfarction ventricular septal defect and ventricular aneurysm, and 1 myxoma of left atrium and abdominal aortal aneurysm. The operative mortality was 5.85% (3/51), and 3 patients died. Cardiovascular surgical patients of over 50 years or with angina pectorsi and ECG confirmed myocardiac ischemia should undergo coronary angiography routinely. If main coronary artery branches stenosis occupied over 50%, CABG must be performed. During the operation revasculariztion should be made as full as possible to enhance myocardiac protection and reduce the ascending aortic cross-clamping time.
