From: Heart beat but not respiration is the main driving force of the systemic venous return in the Fontan circulation

Figure 5

Schematic drawing of the Fontan circulation as established in a patient with hypoplastic left heart syndrome. The right ventricle (RV) serves as the systemic ventricle that pumps blood through the aorta. The drawing shows the Fontan circulation in an anatomy where the IVC is guided through the right atrium by an intraatrial tunnel with fenestration. Systemic venous return from inferior (IVC) and superior (SVC) vena cava drains directly into the right (RPA) and left (LPA) pulmonary arteries without interconnection of a cardiac pump.
