Acute occlusion of a left internal mammary artery graft immediately after redo coronary artery bypass surgery: successful rescue PTCA.

A patient with a patent left internal mammary artery (LIMA) to the left anterior descending (LAD) artery required repeat bypass grafting to the distal right coronary artery (RCA). Intraoperative injury to the LIMA resulted in acute anterior myocardial infarction, which was managed by successful rescue percutaneous transluminal coronary angioplasty (PTCA).
