Abstract: The present invention provides a computer device and a computer-implemented method to quantify the extent of functional coronary artery disease. In addition, the invention provides a computer device for determining the functional pattern of coronary disease in a mammal. It is shown that a mismatch in the extent of CAD between anatomical and physiological evaluations is predictable for an improvement in epicardial conductance with percutaneous revascularization. More particularly the invention provides methods to select a mammal suffering from coronary disease to benefit from a percutaneous coronary intervention.

Abstract: Embodiments include a system for determining cardiovascular information for a patient. The system may include at least one computer system configured to receive patient-specific data regarding a geometry of the patient's heart, and create a three-dimensional model representing at least a portion of the patient's heart based on the patient-specific data. The at least one computer system may be further configured to create a physics-based model relating to a blood flow characteristic of the patient's heart and determine a fractional flow reserve within the patient's heart based on the three-dimensional model and the physics-based model.

Abstract: The present disclosure relates to a system (100) for generating a diagnostic model. The system (100) includes a processor (108) configured to analyse a plurality of reference data sets. The reference data sets each include at least one image (230, 240). The analysis identities at least one feature in each image (230, 240). A metric is calculated in dependence on the at least one identified feature. Outcome data associated with at least some of the reference data sets is acquired. The diagnostic model is compiled in dependence on the at least one calculated metric and the associated outcome data. The present disclosure also relates to a method of generating a diagnostic model; and a non-transitory computer-readable medium.
