LVNC with preserved LVEF.A.Transthoracic ecocardiography, apical 4 chamber view, and B. cardiac magnetic resonance, short axis view: bilayered myocardium, with a thick non-compacted myocardium (NCM) endocardial layer (green line-panel A-B), with broad myocardial trabeculations and deep intertrabecular recesses, communicating with the left ventricular cavity (blue arrows-panel B), and a thinner compacted myocardium (CM) epicardial layer (red line-panel A-B). C. Speckle tracking ecocardiography: slightly decreased deformation of the basal and mid septal segments, with normal apical deformation D-E. Myocardial work analysis: decreased myocardial work efficiency (MWE) in the septal segments and also in the apical non-compacted segments, dominantly in the posterior and lateral ones, by increasing the wasted work (WW), with a preserved constructive work (CW).

LVNC with reduced LVEF.A. 2D transthoracic ecocardiography, apical three chamber view, and B. 3D transthoracic ecocardiography, focused on sections apically to the insertion of the papillary muscles, showing a bilayered myocardium, with a thin epicardial CM layer (red lines-panel B) and a sponge-like NCM endocardial layer (green lines-panel B), gradually increasing in thickness from papillary muscles level to the apex. C. Speckle tracking ecocardiography: gradually decreased deformation from basal anterior and septal segments to mid apical posterior and lateral segments, in a “yin yang” pattern, corresponding to NC segments. D-E. Myocardial work analysis: severely decreased myocardial work efficiency (MWE) in the same segments with reduced deformation, with the collapse of constructive work (CW) and significantly increased wasted work (WW), especially in mid posterior and lateral NC segments.
