Generally acceptable indices for LVNCC consideration by cardiac imaging include demonstration of 1) two ventricular layers: the outer compacted and inner noncompacted zone with a maximum ratio of noncompacted to compacted myocardium >2:1 at end-systole in the parasternal short-axis view; 2) deep trabeculations in the left ventricular apex or midventricular segments of the inferior and lateral wall; and 3) color Doppler evidence of flow within the deep muscular recesses.
The two discrete ventricular layers found in LVNCC should be characterized by an inner (periventricular), spongy, noncompacted layer that lies beneath the outer, more notably dense compact layer.
Nevertheless, a wide neck, the absence of normal ventricular layers and paradoxical contraction point to the presence of an aneurysm (4).
