A mathematical model of the flow of blood through the left coronary artery.

ABSTRACT

Several models of the coronary circulation have been proposed, relating arterial flow waveform and cardiac contraction. Some of them have produced new concepts, such as back pressure, and zero flow pressure, founded on an over-simplified description of vascular collapse. Experimental studies have shown that the actual dynamics of a collapsible tube cannot be adequately described using a lumped parameter model. A distributed parameter model is therefore proposed and compared with the previous models.
