We report a case of septal branch aneurysm. A 61-year-old woman was referred to our hospital because of heart murmur. Septal branch aneurysm(25×15mm)was diagnosed by echocardiography and coronary angiography, and followed up annually with multi-detector row computed tomography(MDCT). Nine years later, another aneurysm proximal to the known aneurysm, which protruded above the epicardium, has rapidly dilated from 5 to 11mm. We therefore performed closure of the orifice of the septal branch concomitant with bypass grafting;left internal mammary artery to distal LAD. After the procedure, the aneurysm in the septum had completely collapsed. Her postoperative course was uneventful.
