[The Fontan operation in tricuspid atresia. Effect of age, shunt and type of atrial pulmonary connection in tricuspid atresia].
Between 1977 and 1988, 20 patients underwent the Fontan operation. Their age ranged from 4 to 24 years (mean 11 years). The basic disease was tricuspid atresia with ventriculo arterial concordance and right ventricular hypoplasia. Pulmonary stenosis was present in 16 patients. Twenty-eight palliative procedures had been performed previously in the group of patients presenting some forms of pulmonary stenosis. In 2 cases a non-valved conduit has been used for correction, in a third case a valve conduit was utilised, and in a fourth case a right atrioventricular connection was carried out. In the remaining 16 patients, a wide posterior connection between the right atrium and the pulmonary arteries was performed. There were 2 early deaths (10%), and 2 late deaths (10%). After a follow-up ranging from 6 months to 11 years, all survivors are in a satisfying functional condition. We think that a wide unrestricting atriopulmonary anastomosis is mainly responsible for those good functional results. Age at operation has not influenced the results. Previous and long standing shunts may be responsible for immediate and late postoperate cardiac failure. Consequently, we now prefer an earlier corrective procedure, particularly when the patient has a patent systemic pulmonary shunt.
