Brief Summary

The ideal grafts for the right coronary artery system in coronary artery bypass surgery remain controversial. The objective of this study is to compare the long-term patency of a right gastroepiploic artery and a saphenous vein graft used for revascularization of the right coronary artery system in off pump coronary artery bypass surgery and to analyze the long-term clinical outcomes. Total 224 patients will be enrolled according to the randomization protocol. Check list

  3. 3.Major adverse cardiac and cerebrovascular event
  4. 4.coronary CT (coronary angiography if needed) at discharge, 1, 5, 10 years postoperatively
