Repair of a left main coronary artery aneurysm using the circumflex femoral artery as a Y-interposition graft.

Left main coronary artery aneurysms are rare, and treatment options are poorly defined.

She was successfully managed with an interposition graft fashioned from the lateral femoral circumflex artery.
