Embodiment Construction

[0022] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0023]In general, the present disclosure relates to performing a digital assessment of a patient's coronary vasculature (e.g., through a patient's coronary vasculature score). In one embodiment, the present disclosure relates to systems and methods for non-invasively assessing coronary artery anatomy, coronary artery disease, myocardial perfusion, and coronary blood flow. The presently disclosed systems and methods help cardiologists assess the complexity and extent of disease in a patient's coronary vasculature and identify the most appropriate intervention (eg, PCI versus CABG). Accordingly, systems and methods are disclosed for assessing the complexity and extent of disease in a patient's coronary vasculature by autom...

Abstract

The present invention discloses systems and methods for providing cardiovascular scoring to patients. A method comprising: using at least one computer system to receive patient-specific data regarding the geometry of a plurality of coronary arteries of a patient; and using at least one computer system to create, based on the patient-specific data, a representation of A 3D model of at least part of the . The method also includes using at least one computer system to evaluate a plurality of characteristics of at least some of the coronary arteries represented by the model; and using at least one computer system to generate the heart rate based on the evaluation of the plurality of characteristics. Vascular scoring. Another method includes generating the cardiovascular score based on a plurality of features evaluated for a portion of the coronary artery having a fractional flow reserve value of at least a predetermined threshold.

Description

[0001] describe technical field [0002] Embodiments of the present disclosure include systems and methods for numerically assessing vasculature, such as scoring coronary vasculature by modeling coronary anatomy. More specifically, embodiments relate to methods for patient-specific scoring of coronary vasculature based on coronary anatomy and optionally also based on fractional flow reserve or other functional measures calculated from computer modeling of blood flow systems and methods. Background technique [0003] Coronary artery disease can produce changes in the coronary arteries, such as stenosis (abnormal narrowing of blood vessels), in the blood vessels that supply blood to the heart. As a result, blood flow to the heart is restricted. Patients suffering from coronary artery disease may experience chest pain during strenuous physical activity (called chronic stable angina) or when the patient is resting (called unstable angina). More severe disease manifestations m...
