Note. Positive values: CFD-simulated values greater than the ECHO measured values; negative values: CFD-simulated values smaller than the ECHO measured values; CFD: computational flow dynamics; ECHO: echocardiography; SRV: single right ventricle; PFR: period of rapid filling; PSF: period of slow filing; PAS: period of atrial systole; PRF: period of rapid ejection; PSE: period of slow ejection; : length of the dominate ventricular chamber; : diameter of the dominate ventricular chamber; : width of the dominate ventricular chamber; SI: spherical index; : area of the atrioventricular valve; : perimeter of the atrioventricular valve; : length of the atrioventricular valve; : basal velocity of the left atrioventricular valve; : medial velocity of the left atrioventricular valve; : apical velocity of the left atrioventricular valve; : basal velocity of the right atrioventricular valve; : medial velocity of the right atrioventricular valve; : apical velocity of the right atrioventricular valve.
