Interventional treatment of the left subclavian in 2 patients with coronary steal syndrome

Figure 3 After selective contrast injection into the left internal mammary artery graft no contrast opafication. It was shown in the left artery disease (red arrow in A). Subsequently, a high grade stenosis of the left subclavian artery was observed (red arrow in B). During coronary angiography retrograde flow from the left artery disease up to the origin of the LIMA graft could be demonstrated (C), despite left main stenosis (orange arrow in D). After angioplasty and stent placement (E) antegrade flow could be re-established in the subclavian artery (F). LIMA: Left internal mammary artery.
