Coronary subclavian steal syndrome is a rare but important condition that occurs after a left internal mammary artery (LIMA) to coronary artery bypass in the setting of a stenotic left subclavian artery. The lack of blood flow through the subclavian artery causes the reversal of flow in the LIMA so that it essentially steals blood from the myocardium. In order to avoid this complication, many surgeons now opt to either revascularize the stenotic subclavian artery prior to coronary artery bypass grafting or to use an alternate vessel as the bypass graft. Here, we present the case of an asymptomatic patient with poor exercise tolerance who was recently diagnosed with both triple-vessel coronary disease and peripheral arterial disease, which was most notably characterized by occlusion of the left subclavian artery. This case demonstrates the surgical management of this complex clinical entity.
