An association between bicuspid aortic valve disease and ascending aortic aneurysma has long been recognized. Root replacement with a composite valve graft for such disease is a well-established technique. But it may involve serious technical difficulties, and may be a more time-consuming procedure than separate valve replacement and graft replacement. We performed an aortic valve replacement with Freestyle stentless valve using the modified subcoronary technique and hemiarch replacement for a 72-year-old man with severe aortic stenosis and ascending aortic aneurysma. Angiographic studies after surgery showed no residual aortic regurgitation (AR) and no deformity of aorta. This technique is an acceptable option for an aortic disease and ascending aneurysma in elderly patients.
