Feasibility and Short-Term Results of Total Arterial Coronary Artery Bypass in Taiwanese

Background and Purpose: Long-term results of coronary artery bypass are limited by progressive atherosclerosis in venous conduits. Arterial conduits are believed to have a better patency rate. A radial artery in composite graft with the left internal thoracic artery makes total arterial revascularization possible in almost all patients. We sought to evaluate the feasibility and short-term results of this grafting strategy. Methods: A total of 381 consecutive patients received elective coronary artery bypass grafting between 1 May 2000 and 31 August 2002. Patients with associated procedures were also included. There were 333 patients without venous conduits. Patients with left ventricular dysfunction were not excluded from total arterial revascularization. Followup time was 13.7 ±7.6 months. Results: Total arterial revascularization was achieved in 88% of the patients. Arterial harvest was easy and simple and complete revascularization could be achieved. The 30-day overall mortality rate was 3.29%. In the patients with left ventricle ejection fraction greater than 0.4, the mortality rate was 2.32%. There were 6 late deaths: heart failure in 2, sepsis in 2, respiratory failure in 1, and pneumonia in 1. Conclusions: It is feasible to use total arterial grafts for coronary artery bypass graft in patients with coronary artery disease. Myocardial revascularization can be complete and the early mortality rate is acceptable.
