Diagram of the human heart Several adaptations of the<unk>  have evolved, but the principle is essentially the same; to replace a diseased aortic valve with the person's own pulmonary valve (autograft), and replace the person's own pulmonary valve with a pulmonary valve from a cadaver (homograft) or a stentless xenograft. It is an alternative to a mechanical valve replacement, particularly in children and young adults. It avoids the need for thinning the blood, has favourable blood flow dynamics and the valve grows as the person grows. The most common reason for performing the<unk>  in children and young adults is for bicuspid aortic valve.
