Key result
Incorporating patient-specific wall motion in TCPC simulations altered predictions of energetic efficiency, hepatic flow distribution, and particle transit time compared to rigid wall models.
Why the study?
How do simulated interventions and wall motion assumptions affect hemodynamic predictions in a patient-specific TCPC model?
How do simulated interventions and wall motion assumptions affect hemodynamic predictions in a patient-specific TCPC model?
Incorporating patient-specific wall motion from 4DMRI in computational fluid dynamics models of TCPC significantly alters predictions of energetic efficiency and flow distribution compared to standard rigid wall assumptions.

Rigid-wall CFD may misestimate TCPC flows; leaves open validation before guiding surgical planning.
Mirabella et al. (2012) studied Total cavopulmonary connections (TCPC) (n=1). Simulated interventions (decreased pulmonary vascular resistance, surgical revision, fenestration) under moving wall assumptions vs. Baseline condition and rigid wall assumption was evaluated on Energetic efficiency, hepatic flow distribution, and transit time. Incorporating patient-specific wall motion in TCPC simulations altered predictions of energetic efficiency, hepatic flow distribution, and particle transit time compared to rigid wall models.
