[Operative transluminal coronary angioplasty as an adjunct to coronary artery bypass grafting: report of two cases].

Two successful cases undergone operative transluminal coronary angioplasty (OTCA) as an adjunct to coronary artery bypass grafting were reported. We performed retrograde OTCA for LAD with sequential stenotic lesions in one case and for Cx with such lesions in another. Postoperative coronary angiograms showed dilatation of the second stenosis and sufficient flow of the proximal branches to the bypass grafts. For the coronary artery with sequential stenotic lesions, OTCA is a beneficial technique for complete revascularization and shortening of aortic cross clamp time.
