Abstract
In order to improve the calculation accuracy of computed tomography angiography-derived fractional flow reserve (FFR
CT), a mathematical model for setting the patient-specific flow boundary condition was proposed, in which some independent physiological parameters, such as myocardial mass, diastolic blood pressure, heart rate and vessel volume were considered. This model was employed to simulate hemodynamics in sixteen patients with coronary stenosis. The results of FFR
CT demonstrated good consistency with invasively measured FFR. The diagnostic accuracy of FFR
CT was 85%. The proposed model offers a new approach to improve the accuracy of FFR
CT, as well as promotes the clinical application of FFR
CT.
