The cardiac index decreased as the duration of Fontan circulation (Fontan duration) increased (<jats:italic>P<\/jats:italic> = 0.005). We found a statistically significant inverse correlation between liver stiffness and cardiac index (<jats:italic>P<\/jats:italic> = 0.02), as well as the ejection fraction (<jats:italic>P<\/jats:italic> = 0.002). Patients with long Fontan durations (\u226520 years) had greater liver stiffness compared with those having a shorter duration (<jats:italic>P<\/jats:italic> = 0.02).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>MRE shows promise as a monitoring tool in the Fontan population, demonstrating an elevated liver stiffness in all patients, which inversely correlated with the MR determined cardiac index. <jats:bold>J.
