Dynamic morphology of the cardiac ventricle.
OBJECTIVE
To describe the outline of the ventricular wall on the basis of physiologic data.


METHODS
Applying the finite deformation theory, we introduced equilibrium equations to obtain the stress-strain relationship of canine myocardial fibers. This was then applied to drawing the shape of the ventricular wall by the finite element method.


RESULTS
The outlines of the ventricle wall corresponded to those seen on an echocardiogram.


CONCLUSIONS
Our method is applicable to the present purpose.
