Fig. 1

Right lateral thoracic view. Vertebral heart size (VHS), long (L) and short (S) cardiac axes are shown. VHS is expressed as total units of vertebral length: 12.2v. Radiographic left atrial dimension (RLAD) is shown (white line). Both measurements were repositioned parallel over thoracic vertebrae beginning with the cranial edge of the fourth thoracic vertebra (T4). The size of the LA was thus expressed as total units of vertebral length: 2.6v
