Abstract
OBJECTIVE: Transient elastography (TE; Fibroscan, Echosens, France) is a non-invasive and reproducible approach to assess liver stiffness (LS). LS has been reported to be associated with fibrosis but central venous pressure (CVP) can also influence LS values. We sought to evaluate the correlation between LS and CVP in a large cohort of children and adults with congenital heart disease. METHODS: All patients referred in our institution between 2012 and 2013 for diagnostic or interventional right heart catheterisation (RHC) were prospectively enrolled excluding patients with acute heart failure, chronic alcohol abuse, chronic liver disease, severe obesity and ascites. Patients underwent LS measurement and CVP measurement by RHC under general anaesthesia within the same or subsequent day. RESULTS: Sixty children (7.4±5.5 years) and 36 adults (38±16 years) were included. Median CVP was 6 mm Hg (range 3-15), median LS was 5 kPa (range 2.8-47.2). LS significantly correlated with CVP (r=0.75, p<10(-4)). In the two subgroups (ie, children and adults), correlation was r=0.68 and r=0.84 (p<10(-4)), respectively. In the overall population, the area under the curve of LS for identification of CVP >10 mm Hg was 0.972 (95% CI 0.855 to 1; p<0.05). Optimal cut-off value of LS for detection of CVP >10 mm Hg was 8.8 kPa (sensitivity=91.67%, specificity=96.25%). CONCLUSIONS: LS measurement using TE is a rapid and reliable method to evaluate CVP in patients with congenital heart disease. Published by the BMJ Publishing Group Limited.
