Claim One:
1. A method of producing a mammalian vascular state score applicable to predict surgical intervention outcome, the method comprising: receiving vascular image data including: relative positions in one or more two-dimensional angiographic images of a plurality of vascular segments and their linkages by branch points; creating a computerized three-dimensional model of the plurality of vascular segments by combining the one or more two-dimensional angiographic images, the three-dimensional model including at least one of a cross-sectional area and a diameter of the plurality of vascular segments; analyzing the three-dimensional model of the plurality of vascular segments to determine locations of potential lesions by identifying portions along the plurality of vascular segments where the at least one of the cross-sectional area and the diameter decrease below a threshold from an expected decrease based on the at least one of the cross-sectional area and the diameter of adjacent portions of the plurality of vascular segments; for each potential lesion: determining a first vascular state scoring tool (“VSST”) subscore based on a size of the potential lesion, determining a second VSST subscore based on a distance of the potential lesion from a branch point in the plurality of vascular segments, determining a third VSST subscore based on a distance of the potential lesion to an adjacent potential lesion, applying a first predetermined weight to the first VSST subscore, a second predetermined weight to the second VSST subscore, and a third predetermined weight to the third VSST subscore, and calculating a total VSST score by combining at least the weighted first VSST subscore, the second VSST subscore, and the third VSST subscore; determining a recommendation based on the total VSST scores of the potential lesions where (i) no recommended action is determined when a combination of the total VSST scores of the potential lesions is below a first threshold, (ii) a percutaneous coronary intervention action is determined when the combination of the total VSST scores of the potential lesions is above the first threshold, and (iii) a coronary artery bypass surgery action is determined when the combination of the total VSST scores of the potential lesions is above a second threshold; and displaying the recommendation.
