Abstract

One embodiment of the present subject matter includes a patch for attachment to a heart having a left atrium which includes a coronary sulcus, a line of reflection between the oblique and transverse pericardial sinuses, and left and right pulmonary veins, the patch sized to have a first edge portion disposed along the coronary sulcus and a second edge portion disposed along the line of reflection between the oblique and transverse pericardial sinuses. In one embodiment, the patch formed by the process including measuring left atrial diameter during over-distension, determining a patch size such that the patch is substantially inelastic when the left atrium is in over-distension, cutting the first edge portion of the patch to fit along the coronary sulcus and cutting the second edge portion of the patch to fit along the line of reflection between the oblique and transverse pericardial sinuses.
