In this study, we performed a detailed hemodynamic and hepatic assessment to analyze the incidence and spectrum of FALD and its association with patients' hemodynamics. From 2017 to 2019, 145 patients underwent a detailed, age-adjusted hepatic examination including laboratory analysis (FibroTest<jats:sup>\u00ae<\/jats:sup>, <jats:italic>n<\/jats:italic>\u2009=\u2009101), liver ultrasound (<jats:italic>n<\/jats:italic>\u2009=\u2009117) and transient elastography (FibroScan<jats:sup>\u00ae<\/jats:sup>, <jats:italic>n<\/jats:italic>\u2009=\u200961). The median patient age was 16.0\u00a0years [IQR\u00a014.2], and the median duration of the Fontan  circulation was 10.3\u00a0years [IQR 14.7]. Hemodynamic assessment was performed using echocardiography, cardiopulmonary exercise capacity testing and cardiac catheterization. Liver ultrasound revealed hepatic parenchymal changes in 83\u00a0patients (70.9%). Severe liver cirrhosis was detectable in 20\u00a0patients (17.1%). Median liver stiffness measured by FibroScan<jats:sup>\u00ae<\/jats:sup> was 27.7\u00a0kPa [IQR\u00a014.5], and the median Fibrotest<jats:sup>\u00ae<\/jats:sup> score was 0.5 [IQR\u00a00.3], corresponding to fibrosis stage\u2009\u2265\u20092. Liver stiffness values and Fibrotest<jats:sup>\u00ae<\/jats:sup> scores correlated significantly with Fontan duration (<jats:italic>P<\/jats:italic><jats:sub>1<\/jats:sub>\u2009=\u20090.013, <jats:italic>P<\/jats:italic><jats:sub>2<\/jats:sub>\u2009=\u20090.012). Exercise performance was significantly impaired in patients with severe liver cirrhosis (<jats:italic>P<\/jats:italic>\u2009=\u20090.003). Pulmonary artery pressure and end-diastolic pressure were highly elevated in cirrhotic patients (<jats:italic>P<\/jats:italic><jats:sub>1<\/jats:sub>\u2009=\u20090.008, <jats:italic>P<\/jats:italic><jats:sub>2<\/jats:sub>\u2009=\u20090.003). Multivariable risk factor analysis revealed Fontan duration to be a major risk factor for the development of FALD (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001, OR\u00a00.77, CI\u00a00.68\u20130.87). In the majority of patients, hepatic abnormalities suggestive of FALD were detectable by liver ultrasound, transient elastography and laboratory analysis. The severity of FALD correlated significantly with Fontan duration and impaired Fontan hemodynamics. A detailed hepatic assessment is indispensable for long-term surveillance of Fontan patients.<\/jats:p>","DOI":"10.1007\/s00246-020-02291-5","type":"journal-article","created":{"date-parts":[[2020,2,1]],"date-time":"2020-02-01T03:02:37Z","timestamp":1580526157000},"page":"736-746","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":62,"title":["Severity of Fontan-Associated Liver Disease Correlates with Fontan Hemodynamics"],"prefix":"10.1007","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2008-2483","authenticated-orcid":false,"given":"Anastasia","family":"Schleiger","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madeleine","family":"Salzmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Kramer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Friederike","family":"Danne","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Schubert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Bassir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"M\u00fcller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans-Peter","family":"M\u00fcller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix","family":"Berger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stanislav","family":"Ovroutski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,2,1]]},"reference":[{"key":"2291_CR1","doi-asserted-by":"crossref","first-page":"240","DOI":"10.1136\/thx.26.3.240","volume":"26","author":"F Fontan","year":"1971","unstructured":"Fontan F, Baudet E (1971) Surgical repair of tricuspid atresia.
