The use of Amplatzer Vascular Plug(®) to treat coronary steal due to unligated thoracic side branch of left internal mammary artery: four year follow-up results.

Left internal mammary artery (LIMA) is the most commonly used graft during coronary bypass surgery. LIMA side branches are clipped during surgery in order to prevent coronary steal. In cases of patent LIMA side branches, there are differingapproaches. Herein, we report a case with patent thoracic side branch of LIMA graft, occlusion of this side branch by Amplatzer Vascular Plug because of documented myocardial ischemia, and long term follow-up results.
