Management of pulmonary regurgitation after tetralogy of fallot repair.

There are an increasing number of patients with moderate to severe pulmonary regurgitation who develop right ventricle dysfunction, with associated symptoms of fatigue and exercise intolerance, after surgical repair of tetralogy of Fallot. Critical longitudinal follow-up of these patients is needed, with assessment by clinical and laboratory studies of right ventricular size, function, and exercise capability. Pulmonary valve replacement is recommended before significant right ventricular dysfunction occurs. The search for an ideal valve to use in this condition continues.
