Methods for Measuring Lateral Cardiac Displacement and Angle of Rotation on CMRI Measurements as shown were made with a horizontal long-axis acquisition at end diastole. %LatD = percentage of circumferential displacement of the right ventricle apex toward the left axilla; ∠septal = angle of interventricular septum with respect to the thoracic midline (degrees). L1 = distance from Line A to the cardiac apex along the internal thoracic cage; L2 = distance from the cardiac apex to Line B along the internal thoracic cage; Line A = passing through the mid-point of the sternum and thoracic vertebrae; Line B = orthogonal to and bisecting Line A, passing through the axilla; Line C = passing through the atrioventricular crux and the cardiac apex.
