Abstract: Objective To summarize the 17-year clinical experience of coronary artery bypass grafting (CABG). Methods From April 1987 to May 2004, total 253 patients with coronary artery disease underwent CABG. The operation were performed in 217 patients under cardiopulmonary bypass (CPB) with moderate hypothermia, because of calcified ascending aorta, partial replacement of ascending aorta wall with apiece of Gore-Tex graft for the proximal anastomosis were done in 10 patients. Off-pump coronary artery bypass grafting (OPCAB) were performed in 30 patients. The operation under CPB with heart beating were performed in 6 patients. Cardiac valvular operations were performed in 15patients. Left atrium myxoma operation was performed in 1 patient. Left ventricular aneurysm plasty operation were performed in 10 patients. Results Total mortality rate was 7.9% (20/253). There was significant difference between the mortality rate of the first 10 years (16.0%,8/50) and that of the last 7 years (5.9%,12/203; χ2=5.62，P lt;0.05). The causes of death were: 3 patients died on table because of low cardiac output after valvular replacement though emergent CABG were conducted, 2 patients died of multiple organ failure after valvular replacement and emergent CABG had undergone, 3 patients died of ventricular fibrillation during closing the sternum, 6 patients died of multiple organ failure caused of severe lung infection, 2 patients died of ventricular fibrillation after operation, and 4 patients died of acute renal failure. One hundred and fiftyseven patients (67.4%, 157/233) were followed up, follow-up time was 6 months to 15 years. Three of them died of unknown causes, most of them have improved life quality. There were 87 patients in New York Heart Association (NYHA) class Ⅰ, 49 patients in NYHA class Ⅱ, 16 patients in NYHA classⅢ, and 2 patients in NYHA classⅣ. Conclusion When the experience of surgery and postoperative care is matured, CABG is a safe method for treatment of coronary artery disease. Partial replacement of ascending aorta wall with GoreTex graft for proximal anastomosis of the graft is acandidate method for the treatment of patients with calcified ascending aorta.
