Geometrical evaluation of the Scar in Left ventricle using TDA

Once the muscular wall dies because of a heart attack; it is recovered by the scar tissue in the many weeks. The structure and mechanical properties of the curative scar are the entire significant determinants of the chance of patients who survive the initial infarction. Here, our goal is to compare the geometry of the scar tissue with the healthy myocardium of the Left ventricular (LV) using Topological Data Analysis (TDA). The morphological image processing method was performed on delayed enhancement CT images for defining the scar regions of the left ventricular endocardial wall using the MATLAB platform. Predicted scar region images and normal myocardium wall images were used for the geometry of the scar tissue and healthy tissue using the geometrical topological approach. Barcode was generated for scar and healthy myocardium and found the dissimilarity distance between scar and the normal tissue distances to be 9.37. This research helps in a better understanding of the normal and scar architecture difference of the LV endocardial wall.
