Pressure-volume loops of the right ventricle-to-pulmonary artery shunt (left) and modified Blalock-Taussig Shunt (right). End-Systolic Pressure-Volume Relationship (ESPVR) and End-Diastolic Pressure-Volume Relationship (EDPVR) lines are marked. Stroke work (shaded blue) and potential energy (shaded red) are illustrated. Potential energy + stroke work = pressure-volume area. PVL = pressure-volume loops.
