The use of an extracardiac conduit in the treatment of complex congenital heart disease was first reported by Rastelli in 1965 (1) and by Ross and Somerville in 1966 (2) with an aortic valve allograft. Irradiated aortic allografts were abandoned early (3, 4). The use of a conduit containing a porcine aortic valve was first reported by Planche (5), but late complications in some series (6, 7) led to the discontinuation of their use. If non-valved conduits and direct cardiopulmonary anastomosis, first described by Lillehei (8), are often advocated, the use of aortic valve allografts is frequently favored by several groups: Shabbo (9) and Radley-Smith (10).
