Method and system for determining treatments by modifying patient-specific geometrical models

摘要

Systems and methods are disclosed for evaluating cardiovascular treatment options for a patient. One method includes creating a three-dimensional model representing a portion of the patient's heart based on patient-specific data regarding a geometry of the patient's heart or vasculature; and for a plurality of treatment options for the patient's heart or vasculature, modifying at least one of the three-dimensional model and a reduced order model based on the three-dimensional model. The method also includes determining, for each of the plurality of treatment options, a value of a blood flow characteristic, by solving at least one of the modified three-dimensional model and the modified reduced order model; and identifying one of the plurality of treatment options that solves a function of at least one of: the determined blood flow characteristics of the patient's heart or vasculature, and one or more costs of each of the plurality of treatment options.

1. A system for evaluating cardiovascular treatment options for a patient, the system comprising: at least one computer system configured to:
create a three-dimensional model representing at least a portion of the patient's heart or vasculature based on patient-specific data regarding a geometry of the patient's heart or vasculature; retrieve a stored plurality of treatment geometries, each treatment geometry including a geometry of a stent or a bypass graft; for each of the plurality of treatment geometries, modify at least one of the three-dimensional model or a reduced order model of the patient's heart or vasculature based on a respective one of the retrieved treatment geometries; determine, for each of the plurality of treatment geometries, a value of a blood flow characteristic calculated from at least one of the modified three-dimensional model and the modified reduced order model; and identify one of the plurality of treatment geometries that solves a function of at least one of: the determined blood flow characteristics of the patient's heart or vasculature, and one or more costs stored in association with each of the plurality of retrieved treatment geometries.
