Circuit resistance modeling in failing heart rotary pump support
Musil J., Leitermann D., Pražák J.
pages 179 - +3p, full text

The stepwise resistance increase caused by the throttle valve usage in the mock-line circuit comprising the pulsating ventricle in failing heart modus and supported by rotary pump set up in parallel was studied. Though this kind of throttling does not simulate the mechanism of the resistance increase in the cardiovascular system rather a significant portion of flow kinetics due to the rotary pump performance was demonstrated. It appears thus important to regulate the support system producing a continuous type of flow to such a regime not allowing the pulsating flow of the failing heart to disappear and preventing the mean systemic pressure value before substantial lncrease.
