A non-invasive screening tool that can identify impending decline is sought. The objective of this pilot study was to assess the microcirculation in Fontan-palliated patients by measuring tissue oxygen saturation (StO\n                    <jats:sub>2<\/jats:sub>\n                    ) in superficial and deeper tissues.\n                    <jats:italic>Approach<\/jats:italic>\n                    : Three patient cohorts were studied: Fontan group (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009\u2009=\u2009\u20098) and two patient control groups, liver disease group (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009\u2009=\u2009\u20098) and tetralogy of Fallot group (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009\u2009=\u2009\u20099). 22 healthy controls were also examined. Superficial and deeper StO\n                    <jats:sub>2<\/jats:sub>\n                    was measured at the forearm, thenar eminence, index and ring fingers of both arms using the LEA O2C spectrophotometry device.\n                    <jats:italic>Main results<\/jats:italic>\n                    : Superficial StO\n                    <jats:sub>2<\/jats:sub>\n                    was reduced in Fontan patients compared to healthy controls (\n                    <jats:italic>p<\/jats:italic>\n                    \u200a\u2009\u2009=\u2009\u20090.002) and tetralogy patients (\n                    <jats:italic>p<\/jats:italic>\n                    \u200a\u2009\u2009=\u2009\u20090.016), but not compared to the liver group (\n                    <jats:italic>p<\/jats:italic>\n                    \u200a\u2009\u2009=\u2009\u20090.313). Deeper StO\n                    <jats:sub>2<\/jats:sub>\n                    was similar between groups (\n                    <jats:italic>p<\/jats:italic>\n                    \u200a\u2009\u2009=\u2009\u20090.112).
