Conceptual model of the ageing Fontan circulation. a) Schematic of i) normal and ii) Fontan circulation; b) relationship between circulatory output at rest and pulmonary vascular resistance (PVR) modulated by ventricular function for a normal subject and patients with a univentricular heart (UVH) and depressed ventricular function; c) relationship between circulatory output at rest and ventricular function modulated by PVR for a normal subject and patients with a UVH and depressed ventricular function; d) relationship between cardiac output, PVR and ventricular function during exercise for normal subjects and patients with Fontan circulation.
