Why the study?
Does ejecting through a rigid versus distensible outflow system alter left ventricular performance and oxygen consumption in isolated hearts?
Does ejecting through a rigid versus distensible outflow system alter left ventricular performance and oxygen consumption in isolated hearts?
Ventricular performance in isolated hearts is significantly modified by the elastic properties of the outflow system, highlighting the need for physiologically accurate distensibility in experimental setups.
No takes yet. Share an insight, caveat, or question.
Requires distensible outflow tracts in isolated heart models; leaves open translation to intact or human physiology.
Salisbury et al. (1962) studied this question.
