There were no significant differences in preoperative characteristics between groups. Mean operation times were 254.6\u2009\u00b1\u200972.2, 213.7\u2009\u00b1\u200957.6, and 253.0\u2009\u00b1\u200981.2\u2005min, and the average numbers of distal anastomoses were 2.9\u2009\u00b1\u20090.9, 2.4\u2009\u00b1\u20090.7 and 2.9\u2009\u00b1\u20091.1 in the Aorta, ITA and LAA groups respectively. Days in intensive care, hospital stay, and major complications did not differ between the groups. Early patency of SVG did not significantly differ among groups: 93.0% in the Aorta group, 98.0% in the ITA group, and 100% in the LAA group. Mean follow-up period was 136.7\u2009\u00b1\u2009295.7 days, and follow-up coronary CTA revealed 18 SVG occlusions (Aorta group <jats:italic>n<\/jats:italic>\u2009=\u20098, ITA group <jats:italic>n<\/jats:italic>\u2009=\u20095, LAA group <jats:italic>n<\/jats:italic>\u2009=\u20095).
