Left internal mammary artery (LIMA) graft is the commonly preferred graft for bypass surgery and is particularly anastomosed to the left anterior descending artery. Stenosis of this graft frequently develops in the distal anastomosis site or within the distal native vessel after surgery, whereas it rarely develops in the ostial site. The pathophysiology of stenosis in the ostial site remains unclear. Percutaneous stenting of ostial lesions has rarely been reported in literature. We believe that such percutaneous transluminal stenting is appropriate for ostial lesions of LIMA grafts.
