Abstract
Systems, methods, and computer-readable media are disclosed for patient-specific modeling of hemodynamic parameters in coronary arteries. Example methods may include performing computational fluid dynamics simulations using a patient-specific coronary artery anatomical model derived from medical imaging data and patient-specific boundary conditions derived from a continuously recorded blood pressure waveform to determine patient-specific hemodynamic parameters in a patients coronary arteries.

A method comprising:
- receiving patient-specific anatomical structure data and patient-specific physiological data, wherein the anatomical structure data comprises structural information about a patient's coronary arteries, and wherein the patient-specific physiological data comprises a continuously recorded blood pressure waveform;
- generating, based at least in part on the anatomical structure data, an anatomical model of at least a portion of the patient's coronary arteries;
- determining, based at least in part on the continuously recorded blood pressure waveform, boundary conditions for a computational fluid dynamics (CFD) simulation of blood flow in the anatomical model;
- simulating blood flow in the anatomical model using CFD and the boundary conditions;
- and
- determining, based at least in part on the simulation, one or more hemodynamic parameters associated with the patient's coronary arteries,
- wherein
- the continuously recorded blood pressure waveform is from a non-invasive measurement, and
- wherein determining the boundary conditions comprises:
- determining, based at least in part on a blood circulation system model and the continuously recorded blood pressure waveform, volumetric blood flow rate data;
- determining, based at least in part on a heart chambers pressure-volume model and the volumetric blood flow rate data, ventricle pressure data;
- determining, based at least in part on a coronary blood flow model, the continuously recorded blood pressure waveform, and the ventricle pressure data, coronary artery inlet flow data, and
- determining, based at least in part on an allometric scaling law and the coronary artery inlet flow data, coronary artery outlet flow data.
