Imaging left ventricular non-compaction in a single patient. A: Short-axis echocardiogram at the level of the chordae tendineae, demonstrating normal-appearing myocardium. B: Apical 4-chamber echocardiogram acquired during early systole, depicting blood flow out of apical sinusoids (blue). C: Short-axis mid-ventricular CMR image, demonstrating abundant trabeculation overlying a very thin compacted myocardial layer in the lateral left ventricular (LV) wall. Red bar: trabecular thickness; white bar: compacted wall thickness. D: 4-chamber CMR image depicting LVNC extending from the apical septum clockwise to the lateral LV wall. RV: right ventricle.
