For the long-term patency, LIMA graft is considered as the ‘gold standard’ for left anterior descending artery (LAD) revascularization. The occlusion of the LIMA graft may be related to atherosclerosis, narrowing at the anastomotic locations, fixed torsions within the graft, straight tubular stenosis, dissection and vasospasm. Late thrombotic occlusion of LIMA is rare and the cause is not known, though case reports can be found in literature. In the present case, we report successful revascularization of the ostial LIMA thrombotic occlusion with percutaneous intervention, in a 71-year old patient diagnosed the acute coronary syndrome, five years after bypass surgery.
