BIOMECHANICS OF LEFT VENTRICULAR ANEURYSM DEVELOPMENT.

Aneurysm of the left ventricle (LV) is generally recognized as a consequence of myocardial infarction. This study provides the mechanics basis of size and shape of a ventricular aneurysm from myocardial infarcts of varying extents and fibrotic to muscular tissue proportion. Infarcts of left ventricles of varying sizes and severities are analysed, to determine the localized myocardial wall deformations or bulges required to enable the damaged myocardial segment with reduced muscular tissue to equilibrate the ventricular chamber.
