Dear Listmembers:

On March 27 I submitted the following request for information:

> I am looking for normal geometrical dimensions for the inside
> of the left ventricle and left atrium for use in a simple finite
> element model of mitral regurgitation (using FIDAP). I really don't
> need the detail provided by, for example, the gigabytes of data
> contained in the NLM visible human. An axisymmetric elliptical model
> may be good enough for a first effort. However, I would also be
> interested in a fairly detailed 3-d mesh of the inner dimensions of the
> left heart for asymmetric simulation. In the latter case, a data set
> of x,y,z points in some common file format would be useful.

Many thanks to those who responded to my request. An edited
summary of responses follows:


I have some fairly detailed FEM mesh data for the entire canine heart as
end-diastole and end-systole, including the LV. The data was obtained
from gated MRI. Drop me a line if you are interested.

An EXCELLENT source of this information is the Geigy Scientific Tables:
Volume 1. They list all dimensions across many age groups and other
prevailing conditions.

You should probably check out the work of Dr. Andrew McCulloch at the
University of California - San Diego. He has developed several Finite
Element models of the heart that include actual geometries. Most of his
work has been done using prolate spheriodal coordinates.
