The internal mammary artery arises from the first part of the subclavian artery. The left internal mammary artery (LIMA) is an excellent graft for myocardial revascularization of the left anterior descending artery. In this article, we describe a quite important variation of an anomalous origin of LIMA, which is rarely seen. In our case, LIMA was arising from the distal of the third part of the subclavian artery. Therefore, it is of utmost importance to perform LIMA angiography before coronary artery bypass grafting surgery.
