Note. CFD: computational flow dynamics; SRV: single right ventricle without heart failure; SRV + HF: single right ventricle with heart failure; 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; Inlet L: left inlet, mitral valve or left atrioventricular valve level; Inlet R: right inlet, tricuspid valve or right atrioventricular valve level; Outlet L: left outlet, aortic valve level; Outlet R: right outlet, pulmonary valve level.
