Mathematical Modeling of the Operation of Pediatric Systems of Auxiliary Blood Circulation of Pulsatile Type with Different Types of Inlet Valves

Abstract

In the work, we present results of the mathematical modeling of hemodynamic processes of a system of auxiliary blood circulation (ABC) of pulsatile type with an ejection volume of 30 cm³ and two types of domestic mechanical heart valves. We show the influence of the type of inlet valve and the angle of its orientation on hemodynamic processes that occur during the operation of the blood pump. On the basis of results obtained, we give recommendations for the selection of the type of valve and its spatial arrangement in order to ensure optimal blood flow and minimization of stagnant zones inside the chamber of the blood pump.
