Once tetralogy of Fallot has been repaired in infancy or childhood, about 5% of individuals require repair or replacement of the pulmonary valve. Because of better surgical results in the present era, long-term survivors are increasingly reported. In most of these individuals, pulmonary regurgitation is the clinical presentation and can be treated with a prosthetic tissue valve. [33]

Porcine valves are preferred over mechanical valves because they have lesser tendency to thrombose.
