a The electrical analog of the modified Norwood procedure with right ventricle (RV) to pulmonary artery (PA) shunt (Sano modification). The pressure gradient across the RV–PA shunt is described as a non-linear function. b Simulated aortic (black solid line), right ventricular (gray solid line) and pulmonary artery pressures (gray dashed line) of the Sano modification.
