Abstract

One embodiment discloses a computerized method of facilitating cardiac intervention, comprising inputting patient data, creating a computerized interactive model of a diseased heart based on the patient data, wherein the model comprises structural elements, simulating at least one proposed cardiac intervention treatment by adding or deleting structural elements 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.

Independent Claims | See all claims (44)

  1. 1. A method of diagnosing a human heart, comprising: providing to a computer system a plurality of first images of heart tissue from the heart; using the plurality of first images to create at least one second image of human heart tissue using the computer system, comprising: creating endocardial and epicardial left ventricle wall contours; automatically segmenting at least a portion of left ventricle wall endocardial contours 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 contours 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; wherein the second image comprises one or more structural elements; and comparing at least one structural element to one or more heart reference structural elements in a database to assess a state of the heart.
  2. 32. A method of diagnosing a human heart, comprising: providing two or more sectional views of heart tissue from the heart to a computer system; creating endocardial and epicardial left ventricle wall contours; automatically segmenting at least a portion of left ventricle wall endocardial contours of at least two of the sectional views into a selected number of endocardial left ventricle wall points; automatically segmenting at least a portion of left ventricle wall epicardial contours of at least two of the sectional views into a selected number of epicardial left ventricle wall points; 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; and automatically comparing the model of at least a portion of the left ventricle wall with one or more corresponding portions of reference left ventricle wall in a database; and automatically assessing a state of the human heart.
