(a): Computer simulation model for a 4 yr old with univentricular Fontan circulation without (left) and with (right) cavopulmonary assist device (VIP) support. Systemic ventricular pressure (SVP, solid), Aortic pressure (AoP, dashed), pulmonary artery pressure (PAP, dash-dot), and vena cava pressure (VCP, dotted) waveforms generated by the (b): Aortic (AoP) and single ventricular pressure waveforms (SVP) obtained from the mock circulation studies with no VIP support (left) and with 100% VIP support (right). VIP support increases ventricular end diastolic pressure and systolic and diastolic pressures. (c): Single ventricular pressure volume loops for Fontan circulation (solid), and Fontan circulation with cavopulmonary assist device (VIP) support (dashed) from the computer simulation show that VIP support increases the stroke volume, peak ventricular pressures, and end systolic and end-diastolic ventricular volumes.
