(a) Resting flow waveforms of IVC and SVC of Patient 1 at FB and BH conditions for 1 respiratory cycle (4 cardiac cycles for BH), along with the respiratory cycle determined by tracking the chest wall motion from the IVC MRI images; (b) Particle tracking results within the TCPC under simulated FB and BH conditions for Patient 1 at various time points. Particles were seeded at the IVC and SVC for 1 respiratory cycle, and were allowed to advect for additional 5 respiratory cycles.
