Abstract

One embodiment discloses a computerized method of facilitating cardiac intervention, comprising inputting patient data, creating a computerized interactive model of a heart based on the patient data, wherein the model comprises features, simulating at least one proposed cardiac intervention treatment by adding or deleting features to the model, and determining the effects of the proposed cardiac simulation upon the entire model. Simulations may be repeated to allow the user to determine an optimal cardiac intervention. Additionally, a template may be created from the model to use as a guide during the cardiac intervention.

Claims

1. A method of assessing a viability of human heart tissue, comprising:

providing two or more images of heart tissue from a human heart to a computer system;

dividing at least two of the images into a plurality of sections, comprising;

creating endocardial and epicardial left ventricle wall boundaries;

automatically segmenting at least a portion of left ventricle wall endocardial boundaries of at least two of the provided images of heart tissue into a selected number of endocardial left ventricle wall points;

automatically segmenting at least a portion of left ventricle wall epicardial boundaries of at least two of the provided images of heart tissue into a selected number of epicardial left ventricle wall points; and

automatically using endocardial left ventricle wall points and epicardial left ventricle wall points to create a model of at least a portion of the left ventricle wall over one or more periods of time;

assigning a value to at least one of the sections of the model, wherein the value is a function of a feature of the section; and

using the value of at least one of the sections to assess viability of human heart tissue in or proximate to at least one of the sections with an assigned value.

2. The method of claim 1, wherein the feature of the section is a color of the section.

3. The method of claim 2, wherein the color of the section comprises grayscale.

4. The method of claim 1, wherein the computer system divides at least one of the images into a plurality of images.

5. The method of claim 1, wherein the computer system assigns the value to at least one of the sections.

6. The method of claim 1, further comprising extrapolating at least one feature from at least one of the image.

7. The method of claim 1, wherein the computer system uses the value assigned to at least one of the sections to assess viability of human heart tissue in or proximate to at least one of the sections with an assigned value.

8. The method of claim 1, further comprising creating at least a second image of human heart tissue, wherein at least a portion of the second image appears at least three-dimensional.

9. The method of claim 1, further comprising creating at least a second image of human heart tissue, wherein at least a portion of the second image appears at least three-dimensional with different viabilities indicated on the image.

10. The method of claim 9, further comprising displaying the three-dimensional image.

11. The method of claim 1, further comprising creating a report comprising an image of human heart tissue appearing at least thee-dimensional, wherein the image is divided into sections based on the assessed viability of the sections.

12. A system configured to assess a viability of human heart tissue, comprising:

a CPU; and

a system memory coupled to the CPU, wherein the system memory stores one or more computer programs executable by the CPU;

wherein one or more computer programs are executable to;

provide at least two images of heart tissue from a human heart to a computer system;

create endocardial and epicardial left ventricle wall boundaries;

automatically segment at least a portion of left ventricle wall endocardial boundaries of at least two of the provided images of heart tissue into a selected number of endocardial left ventricle wall points;

automatically segment at least a portion of left ventricle wall epicardial boundaries of at least two of the provided images of heart tissue into a selected number of epicardial left ventricle wall points;

automatically use endocardial left ventricle wall points and epicardial left ventricle wall points to create a model of at least a portion of the left ventricle wall over one or more periods of time; and

assess viability of human heart tissue by using the computer system to assess a contrast between at least two sections in the model.
