BackgroundThe association between the prevalence of cirrhosis and the types of Fontan operations remains unclear.MethodsWe conducted a retrospective chart review of 332 patients who underwent the Fontan procedure at our institution. Four patients who underwent the atriopulmonary connection Fontan were excluded from the analysis. Patients who had intracardiac-extracardiac conduit (126) between 1989 and 2021 were pooled with those having extracardiac conduit (ECC) (134). The 260 patients who underwent the ECC and the 68 patients who had the lateral tunnel (LT) Fontan constitute the core of the study.ResultsMedian age at the Fontan procedure was 23.7 months (interquartile range [IQR], 20.8-32.6) in the LT group, compared with 28.8 months (IQR, 24.6-39.5) in the ECC group (P < .01). The median follow-up was 14.8 years (IQR, 12.5-16.5) in the LT group and 7 years (IQR, 2.8-10.4) in the extracardiac conduit group. During the follow-up period, 3 patients (4.4%) with LT and 17 patients (6.5%) with ECC (11 patients with 16 mm or less conduit size) were diagnosed with cirrhosis. The prevalence of cirrhosis at 1, 5, 10, and 15 years was 0%, 0%, 0%, and 4.4% in the LT group, respectively, and 0%, 0.9%, 7.7%, and 29.8% in the ECC group (P < .01) Rates of mortality, Fontan revision, Fontan takedown, transplant, and complications were comparable between the 2 groups.ConclusionsThe extracardiac conduit Fontan seems to be associated with faster development of cirrhosis.Copyright © 2024 The Authors.
