“…26 In our latest study, we introduced a new model with 42 compartments which was able to mimic the operation of the cardiovascular system under normal conditions. [27][28][29] In this study, we tried to advance our previous models by the inclusion of cerebral compartments and normal blood flow inside the efferent arteries, including the LACA-A2, RACA-A2, LMCA, RMCA, LPCA-P2 and the RPCA-P2. The effects of an aneurysm on the whole circuit by increasing the incremental rate of aneurysm of the left internal carotid artery are studied.…”

The circle of Willis (CoW) is a key asset in brain performance as it supports adequate blood supply to the brain. The lumped method (electrical equivalent circuits) is a useful model to simulate the process of the human cardiovascular system. In this study, the whole cardiovascular system is modeled, using an equivalent electrical circuit to investigate an aneurysm in an artery. The cerebrovascular system consists of 29 compartments, which includes the CoW. Each vessel is modeled by a resistor, a capacitor and an inductor. Using MATLAB Simulink, the left and right ventricles are modeled by controlled voltage sources and diodes. The effects of the left internal carotid artery aneurysm (Fusiform) on the pressure of the efferent arteries in the circle of Willis are studied. The modeling results are entirely in agreement with the available clinical observations. The results of the present study may have clinical implications for modeling different cardiovascular diseases, such as arterial stiffness and atherosclerosis.

This paper describes simulation and analysis of the human cardiovascular system using a complex electronic circuit. In this study we have taken a slightly different approach to the modelling of the system and tried to advance existing electrical models by increasing more segments and parameters. Anatomical and physiological data for circuit parameters have been extracted from medical articles and textbooks. The frequency of heart is 1 Hz and the system operates in steady state condition. Each artery is modelled by one capacitor, resistor and inductor. The left and right ventricles are modelled using AC power suppliers and diodes. The results of the simulation including pressure graphs exhibit operation of the cardiovascular system under normal condition. From the electrical cardiovascular model we have analysed some cases which reflect the real time functioning of the human cardiovascular system. Hence we have changed the circuit parameters and observed the output responses which satisfy the actual human responses in different situations.

“…We have tried to advance existing models by dividing aorta to different sections in order to study the pathology accurately, meanwhile the arterial system of the model are more detailed. Firstly, We modeled the cardiovascular system with an equivalent circuit and active elements [6] to enable us to show the normal and abnormal operation of the system then, in order to study the influence of aorta aneurysms, the geometry of different section of the artery including abdominal and thoracic were generated. The pressure drops which are caused by aneurysms were determined using CFD method.…”

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.
