Between 1979 and 1989, 84 patients underwent a Fontan operation or one of its modifications; the ages ranged from 5 months to 31 years. Patients were placed into five anatomic groups: 1) tricuspid atresia la (3 cases, 1 death, 33.3%); 2) tricuspid atresia lb (48 cases, 5 deaths, 10.4%); 3) single ventricle (18 cases, 2 deaths, 11.1%); 4) pulmonary atresia, intact ventricular septum (5 cases, 1 death, 20.0%); 5) complex anomalies (10 cases, no deaths). The subgroup of complex anomalies was divided in: with situs inversus and with situs solitus. In the majority of these patients, additional procedures were performed; in 5, one A-V valve was closed; in 2, complex atrial septation was done; in 1, a mitral valvuloplasty and the septation of the single atrium were performed; in 1, the section of an anomalous pathway (Kent bundle) was carried out.
