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.
