Key result
A physiological flow path in a simulated ventricle did not save energy compared to a nonphysiological path (0.864 vs. 0.874 J at 60 bpm) but facilitated blood clearance at high heart rates.
Why the study?
Does a physiological flow path save energy or improve blood clearance compared to a nonphysiological flow path in a computational heart model?
Does a physiological flow path save energy or improve blood clearance compared to a nonphysiological flow path in a computational heart model?
Absolute Event Rate: 0.864% vs 0.874%
A computational heart simulator demonstrates that the physiological looped heart flow path does not save energy but facilitates blood clearance and prevents mixing at high heart rates.
No takes yet. Share an insight, caveat, or question.
No energy benefit from physiological flow in ventricular models; leaves open clearance advantages at high rates for further simulation studies.
Watanabe et al. (2008) studied Cardiac hemodynamics. Physiological flow path vs. Nonphysiological flow path was evaluated on Work performed by the ventricular wall at 60 beats/min (J). A physiological flow path in a simulated ventricle did not save energy compared to a nonphysiological path (0.864 vs. 0.874 J at 60 bpm) but facilitated blood clearance at high heart rates.
