Fig. 2From: Partial cavopulmonary assist from the inferior vena cava to the pulmonary artery improves hemodynamics in failing Fontan circulation: a theoretical analysisAn electrical analog of the Fontan circulation. In the partial cavopulmonary assist (CPA) model, a rotational pump is added between the inferior systemic venous resistance (R v,s,i) and the junction of superior and inferior systemic venous return. In the total CPA model, a rotational pump is added between the junction of superior and inferior systemic venous return and the pulmonary characteristic impedance (R c,p)Back to article page
