Application of Mathematical Modeling for Simulation and Analysis of Hypoplastic Left Heart Syndrome (HLHS) in Pre- and Postsurgery Conditions

Figure 2

Lumped parameter model of HLHS. Model is made up of three parts: (a) hypoplastic left heart, (b) pulmonary circulation, and (c) systemic circulation. Direction of blood flow is shown by arrows. ASD: atrial septal defect; RA: right atrium; LA: left atrium; TV: tricuspid valve; RV: right ventricle; PV: pulmonary valve; PA: pulmonary artery; PAB: pulmonary arterial bed; PVB: pulmonary venous bed; PDA: patent ductus arteriosus; DA: descending aorta; SAB: systemic arterial bed; SVB: systemic venous bed; SLV: systemic large veins.
