Many surgeons have modified the technique to reduce bleeding from anastomosis line since Bentall and De Bono introduced aortic root replacement using a composite graft. We present a new composite, butterfly wing-shaped, valve graft fixated using hand-made double sewing cuff. The "wings of a butterfly" technique is a method of reinforcement suturing between an added sewing cuff and residual aortic wall at the proximal stump and helps to reduce bleeding after the modified Bentall's procedure.
