Abstract: Methods and systems for cardiovascular structure reconstruction are provided. A method of reconstructing a cardiovascular structure may include imaging the cardiovascular structure, producing a three-dimensional model of the cardiovascular structure based on the imaging, and creating a three-dimensional model of a patch corresponding to the three-dimensional model of the cardiovascular structure, where the patch is configured to reconstruct the cardiovascular structure to a normal geometry. A patch for a cardiovascular structure may include at least one layer of anisotropic material including an outermost perimeter and one or more notches extending inward from the outermost perimeter, where each of the one or more notches creates a discontinuity in the outermost perimeter. In some cases, each of the one or more notches includes a first edge and a second opposing edge, and the patch further includes one or more sutures configured to secure the first edge to the second opposing edge.
