Coronary angiogram before the redo coronary artery bypass grafting. Coronary angiogram before the redo coronary artery bypass grafting shows patent bypass grafts 27 years after the initial coronary artery bypass grafting to the second diagonal branch using the left internal thoracic artery (a), and to the obtuse marginal branch using a saphenous vein graft (b). However, the left anterior descending artery (red arrows) was supplied only via poor collateral flow from the right coronary artery (c)
