Popis: Aims Fontan operation represents the surgical palliative option for congenital heart disease with single ventricle physiology. With the improvement of surgical and percutaneous technique, we are facing a growing population of patients with an unique pathophysiology and potential complications. Methods and results Patients that underwent Fontan palliation in our centre between 1993 and 2016 were included in this prospective study. We excluded patients with major congenital renal anomalies, those that underwent cardiac transplantation, and redo-Fontan patients. All the subjects underwent clinical evaluation, laboratory exams with complete renal and hepatic function, transient hepatic elastography, and complete cardiac evaluation. We used Schwartz equation for estimating glomerular filtration rate in patients younger than 18 years, and CDK-EPI equation for adult patients. We enrolled 35 patients, 46% female (N = 16), and 54% male (N = 19). Medium age was 17 years old, median age 15 years old (range: 10–31 years old). Medium time from Fontan completion was 160 months (range: 57–340 months). Regarding to cardiac anatomy, 10 patients had functional single left ventricle (FSLV, 28.5%) and 21 a functional single right ventricle (FSRV, 60%); 4 patients had undetermined single ventricle (11.5%). Total cavo-pulmonary connection (TCPC) with intracardiac lateral tunnel was performed in 7 patients (20%, N = 7), whereas 28 patients had TCPC with external conduit (80%). Data from echocardiographic evaluation showed a medium EF established with Simpson’s method of 60% in patients with FSLV; patients with a FSRV or undetermined single ventricle had a medium FAC of 41.1%, with 15.1% having a reduced FAC Conclusions Our population showed an higher prevalence of FSRV Fontan patients, with an expected lower systolic function compared with FSLV. 2D evaluation of systolic function showed a linear inverse correlation with renal function, suggesting that Fontan patients need a closer renal monitoring. Hepatic stiffness, which is a warning sign of potential hepatic cirrhosis need to be monitored in all Fontan patients, especially those with a worse AV valve insufficiency.
