Assessment of the trabeculated to compacted layer ratio of the left ventricle using short and longitudinal axis views in young patients presenting with ventricular dysrhythmias

Background Cardiac MRI (CMR) is increasingly being used clinically to assess the regional thickness of the compacted and trabeculated layers of the left ventricle (LV) in patients with suspected non-compaction. However, there is no consensus on whether the short or longitudinal axis view is preferred. We sought to assess the compacted and trabeculated layers in a young ventricular dysrhythmia population with age matched controls and to compare the measurements derived from both the short axis and longitudinal views.
