Background: LIMA/coronary steal syndrome is a rare but significant complication in patients with severe coronary artery disease (CAD) who have undergone coronary artery bypass grafting (CABG) and concurrently have high-flow arteriovenous (AV) fistulas for hemodialysis. The left internal mammary artery (LIMA) is a preferred conduit for CABG due to its long-term patency and ability to sustain myocardial perfusion. However, in patients with end-stage renal disease (ESRD) requiring hemodialysis, excessive AV fistula flow can divert blood away from the LIMA graft, leading to myocardial ischemia despite graft patency. Early recognition and appropriate intervention are essential to prevent further deterioration of cardiac function.
