As part of an etiological assessment of dyspnea, a transthoracic echocardiography showed a dilated left ventricle, reduced left ventricular ejection fraction at 40%, septo-apical myocardial hypokinesia and left ventricular hypertrabeculation. ( Figure 1).

The ratio of noncompacted myocardium to compacted myocardium was 3.1. ( Figure 2). It was concluded that the appearance was most likely left VNC cardiomyopathy with a LVEF at 30% without intra-cardiac thrombus or mitral insufficiency ( Figure 2).

The axial dissection of the heart found left ventricle hypertrabeculation with parietal thinning measured at 0.5cm and some intra-cavitary adhering thrombi ( Figure 3).
