Coronary artery bypass graftings were performed to the left circumflex artery (LCX) system in the atrioventricular groove (#11 or #13) in addition to revascularization to the left anterior descending artery system using conventional technique in 10 patients with left main trunk lesion. Distal anastomosis was done at #11 of LCX in 6 patients using saphenous vein graft, and at #13 of LCX in 4 patients using 2 saphenous vein grafts and using 2 internal thoracic artery grafts. The mean flow rate of SVG operated by this technique showed larger values than that of SVGs by sequential bypass or individual bypass technique to #12 and/or #14 of LCX. Postoperative angiographies showed excellent graft patencies and symptomatic improvements were achieved. This technique of coronary artery revascularization is recommended and useful in patients whose #12 and #14 of LCX system is too small to make distal anastomosis.
