OBJECTIVE: To show the mortality rate of children undergoing to Fontan operation and determine whether the hypoplastic left heart syndrome (HLHS) is a risk factor for hospital mortality. METHODS: From August 2001 to June 2008, 76 patients underwent Fontan operation and were divided into two groups: group A with 54 patients, 31 (40.7%) patients with tricuspid atresia and variants, six (7.8%) of double-inlet left ventricle, four (5.3%) and atrioventricular septal defect and total 13 (17.1%) of other complex congenital heart disease and group B all patients with HLHS a total of 22 (28.9%) patients. RESULTS: Group A patients had a mean age of 6.47 years ± 4.83 and group B of 2.08 years ± 0.24 P <0.001, the average weight was 22.42 ± 11.04 against 12.99 ± 1.2 P = 0.016, the mean CPB time was 119.5 min versus 113.3 min P = 0.0, with a mean clamping time of 74.8 min and 73.5 min p = 0.75. The mean ICU stay was 4.1 days for group A versus 7.52 days for group B p = 0.0003. In total (group A + B) three patients died, with hospital mortality of 3.9%, and one patient with HLHS (4.54%) (P <0.001, 95% CI 0.001 to 0.228). CONCLUSION: Our study shows that despite higher morbidity in HLHS is not a risk factor for hospital mortality.
