US 2022/0044825 A1 · MODELING OF FLOW THROUGH A LEFT VENTRICULAR ASSIST DEVICE (LVAD)

Abstract

A model of flow through a left ventricular assist device (LVAD) can be used for preoperative planning of implantation of the LVAD into a patient and/or optimization of the LVAD after implantation into the patient are described. At least one imaging data set related to a patient and at least one physiological data set related to the patient can be received. An ideal parameter related to the LVAD can be determined based on the at least one imaging data set related to the patient, the at least one physiological data set related to the patient using a model of circulation in a large spatial region of the patient's body and a three-dimensional anatomical model of at least one component of the region of the patient's body and at least one component of the LVAD. Flow patterns within the three-dimensional anatomical model are calculated using computational fluid dynamics.
