[Experimental simulation of dyskinetic heart wall aneurysms]

A mechanical model for the quantitative investigation of the loss of performance of a ventricle caused by aneurysms of different sizes is described. The model permits an accurate simulation of the geometry of both the ventricle and the aneurysm, as well as the mechanical flow situation as expressed by the changing pattern of the intraventricular pressure. Investigations are limited to a determination of the loss of ventricular performance brought about by the dyskinetic motion of the aneurysm.
