Abstract

To explore the assistant effect of balloon pump coupled with ascending aorta on heart failure, the model of balloon pump coupled with ascending aorta and the model of valve added after balloon pump were established on the basis of systemic blood circulation system model by electro-hydraulic analogy, and the mathematics equation was established according to the equivalent circuit diagram.Using Matlab to complete numerical simulation and the auxiliary effect of the two methods on heart failure was explored. It is found that both models can increase aortic diastolic pressure, reduce left ventricular ejection resistance and ventricular work, and increase stroke output and ejection fraction. Both models have auxiliary effect on heart failure. By comparing between the two methods, it is found that the artificial valve placed behind the balloon can prevent the peripheral blood from refluxing during the balloon deflation, enhance the suction of aorta, reduce the pressure of aortic sinus, and further reduce the left ventricular ejection resistance and ventricular work. The model of balloon-assisted valvular implantation coupled with ascending aorta is feasible. It has better effect on heart failure.
