Abstract
Patent coronary artery bypass grafts are at risk of injury during redo cardiac surgery. In particular, damage to a patent left internal mammary artery (LIMA) graft during repeat surgery is a well-described and potentially lethal complication [1]. Precise anatomical information is important for planning the surgical approach in reoperative cardiac surgery. The standard preoperative work-up including coronary angiography and chest X-ray may provide unsatisfactory information about the exact anatomical location of grafts [2]. This case report illustrates the value of preoperative computed tomography angiography (CT angiography) in patients undergoing repeat cardiac surgery after prior aortocoronary bypass surgery.
