“…Our method has shown that compliance of aneurysm aorta increased with the rate of aneurysm size growth. This is according to experimental observations [7] . Our results show that abdominal I aneurysm of aorta causes the pulse pressure (systole minus diastole) to rise from normal value of 40mmHg (volt) to average of 96 mmHg.…”

“…The study of 12 patients observed that there was an inverse relationship between maximum diameter of aneurysm, E and stiffness. The abdominal aneurysm aorta expansion was only associated with a significant increase in E and stiffness in non operated aneurysm [7] . However, the criteria for open repair were not clearly defined.…”

“…Therefore, genetic parameters and their variations could also affect on the elastic properties of the aorta and an important rule of aneurysm growth. It shall be noted that although elasticity module (E) decreased as a result of aneurysm which means that large aneurysms tended to be less compliant but the relationship is weak [7] . The study of 12 patients observed that there was an inverse relationship between maximum diameter of aneurysm, E and stiffness.…”

“…The aorta aneurysm has primarily been studied and the earliest study was by Long [7] and Morris-Stiff [8] who studied the compliance of aorta with aneurysm and observed the effects of aneurysm clinically. More recent studies have used clinical data to investigate the aorta aneurysm [9][10][11] .…”

Abstract:The fusiform and saccular aneurysms in different aorta artery sections were studied using an electronic circuit of cardiovascular system. The geometrical model of each artery section including thoracic and abdominal were generated in accordance with original anatomical data. By increasing the rate of aneurysm in each studied section, the pressure drop were calculated using CFD method, furthermore the compliance variations due to aneurysms were determined by mathematical method. The equivalent electronic circuit was then used to study the effects of the pressure drops and compliance variations on whole cardiovascular system. The results of the simulation exhibited the features of the pathology, including hypertension, the increase of the pulse pressure with the rate of aneurysm and the large magnitude of back flow during systole. Finally, the obtained results were compared with relevant clinical data .We have concluded from the study that aorta aneurysms in both fusiform and saccular, especially at highest diameters, may be the most important determinant of the artery rapture and heart failure.

“…The aortic aneurysm has primarily been probed and the compliance of aortic aneurysms was investigated and the effects of the pathology were observed (Long et al, 2004;Morris-Stiff et al, 2005). The cardiac pressure-volume loops for aortic aneurysms has been presented by utilizing electronic cardiovascular modeling (Abdolrazaghi et al, 2008).…”
