title: Fontan operation: modification of the valve position in conduit with brief review of the literature.
abstract: A Fontan operation was performed on a 10-year-old child for correction of tricuspid atresia. A xenograft, valved conduit was used to establish continuity between the right atrium and the small right ventricle. Atrial and ventricular septal defects were repaired with Dacron patches. Two hours postoperatively, the patient suffered a cardiac arrest secondary to hypoxia and was successfully resuscitated. Partial recurrence of a right-to-left shunt at the atrial level necessitated the patient's return to surgery. The insufficient conduit was replaced and the leaking patches were resutured. The conduit was shortened to one-third its length, and the conduit valve was repositioned directly at the proximal end, over the right atriotomy. Ten months postoperatively, the patient remains in stable condition.
