Pectus index and CMR tissue tracking.
(A) The Haller Index (HI) is a ratio of the transverse diameter of the chest (line a) to the distance between the posterior aspect of the sternum and the anterior portion of the vertebra (line b): HI = a/b. The correction index (CI) measures the depression of the sternum relative to the anterior chest: CI = [(c-b)/c] x 100. (B) Right ventricular longitudinal strain. (C) and (D) Mid-cavity circumferential strain and peak value was recorded. The yellow colored contours show the tracking of the ventricle.
