“…Recent advances in surgery and perioperative care have improved Fontan patient survival [ 4 ]. However, long-term outcomes remain challenging, which calls for the integration of novel methods such as computational modelling into cardiology practice [ [6] , [7] , [8] ]. The Fontan circulation has been simulated using three-dimensional (3-D), one-dimensional (1-D), and zero-dimensional (0-D) haemodynamic models.…”
