Diagram of the human heart. Several adaptations of the Ross procedure 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.
A pulmonary homograft (a pulmonary valve taken from a cadaver) is then used to replace the patient's own pulmonary valve. This procedure was first performed in 1967 and is used primarily in children, as it allows the patient's own pulmonary valve (now in the aortic position) to grow with the child. [17] Tissue valves can last 10–20 years. [18]
The durability of homograft valves is probably the same as for porcine tissue valves. Another procedure for aortic valve replacement is the Ross procedure (after Donald Ross) or pulmonary autograft. The Ross procedure involves going to surgery to have the aortic valve removed and replacing it with the patient's own pulmonary valve.
Moreover, while there is a decreased reoperation rate in the first 5 years seen with the Bentall procedure, the need for reoperation after Bentall and VSARR are then comparable thereafter.

The catheter procedure was invented and developed in Aarhus University Hospital Denmark in 1989 by Henning Rud Andersen, [28] who performed the first animal implantations that year. [29] The first implantation in a human was performed on 16 April 2002 by Alain Cribier in Hopital Charles Nicolle, at the University of Rouen , France. [ 30 ]
