Preparation of left ventricular wall samples for biaxial testing. (A) The left ventricle (LV) of the rat heart is shown, with the position of the left anterior descending (LAD) coronary artery, the ligating suture, the ischemic territory, and the four borderzone injection sites labeled. (B–C) The septum and lateral-most aspect of the LV wall are excised, and the remaining anterolateral LV wall is flattened into a square block of tissue. (D) The LV wall sample is mounted onto the biaxial testing device, aligned along the circumferential and longitudinal axes of the heart.
