In this study, we have focused on obtaining the pressure volume graphs of left ventricle for abdominal aortic aneurysm cases by utilizing a cardiovascular electronic circuit. In addition, these graphs were compared with a normal condition. The electronic circuit of the cardiovascular system consists of 42 segments including the main arterial vessels. Anatomical and physiological data for circuit parameters have been extracted from medical articles and textbooks. The pressure-volume graphs were obtained for fusiform and saccular aortic aneurysms at different values by using Matlab software. Finally, the results were compared with relevant clinical observations.
