Objectives: We have used the saphenous vein graft (SVG) to revascularize the right coronary artery (RCA) in cases with <90% stenosis and the gastroepiploic artery (GEA) in cases with ≥90% stenosis. This study was conducted to assess the validity of our approach. Methods: 75 patients who had undergone isolated coronary artery bypass grafting including the RCA between March 2005 and July 2011 were studied. Early and mid-term outcomes were compared between 2 groups of patients who had received either the GEA or the SVG graft to revascularize the RCA. Results: Early graft patency rates were 89% in the SVG group and 91% in the GEA group, while the rate of freedom from cardiac adverse events at 48 months was 96.4% in the SVG group and 97.7% in the GEA group; there were no significant differences between the groups. Conclusion: Early and midterm outcomes demonstrated the validity of our approach for selecting grafts based on the rate of stenosis in the RCA.
