Short-axis echocardiographic end-systolic view consistent with left ventricular noncompaction

Parasternal-short-axis echocardiographic end-systolic view of the left ventricle. The ratio of noncompacted myocardium (spanned by the red line [top section]) to compacted myocardium (spanned by the yellow line [bottom section]) is 3:1. Thickened left ventricular wall with a ratio ≥2:1 of non-compacted to compacted myocardium at end-systole and prominent trabecular meshwork in the LV apex or midventicle (along with color Doppler evidence of flow within the deep intertrabecular recesses) are the criteria for left ventricular noncompaction proposed by Jenni et al.
