The Fontan procedure is frequently used for correction of complex congenital heart disease, but the postoperative morbidity and mortality rates are still high. The results in 35 consecutive patients who underwent the Fontan procedure from January 1980 to June 1991 are reviewed. The patients comprised 26 boys and nine girls aged from 1.7 to 14.8 (mean 6.8) years. The underlying diseases were univentricular heart (19 patients), tricuspid atresia (eight), complete atrioventricular canal (three patients, two of whom had straddling atrioventricular valve) and other conditions (five). Valved conduits were implanted in four patients and non-valved in 15. Direct right atrium-pulmonary artery anastomosis was performed in 16 patients. The overall hospital mortality rate was 23% (eight patients); in the final year of the review it was 11%. Follow-up of the survivors ranged from 1 to 120 (mean 25) months. All except two patients attained New York Heart Association functional class I or II. Three patients underwent reoperation for atrioventricular valve regurgitation and conduit stenosis with good results. It is concluded that the Fontan procedure is a good palliative operation for complex congenital heart disease.
