(A) Effect of CVP on all-cause mortality in early and late Fontan survivors. High CVP has a significant adverse impact on mortality in both groups of survivors. The right upper figures show that Fontan survivors with high CVP (≥14 mmHg) have a high mortality. (B) Effect of arterial blood SaO₂ on all-cause mortality in early and late Fontan survivors. Low SaO₂ has a significant adverse impact on mortality in both groups of survivors. (A) and (B) are modified from those in reference ²³. The right lower figures show that Fontan survivors with low SaO₂ (≤93% in early survivors, ≤92% in late survivors) have high mortality.

CVP = central venous pressure; SaO₂ = oxygen saturation.
