Left ventricular non-compaction (LVNC) is characterized by prominent left ventricular trabeculae and deep inter-trabecular recesses. The myocardial wall is often thickened with a thin, compacted epicardial layer and a thickened endocardial layer. In some patients, LVNC is associated with left ventricular dilatation and systolic dysfunction, which can be transient in neonates. [ http://www.ncbi.nlm.nih.gov/pubmed/17916581 ]

Left ventricular noncompaction cardiomyopathy (LVNC), also known as spongy myocardium, is a distinct form of cardiomyopathy occurring in-utero when segments of spongy myocardium fail to transform into compact, mature musculature resulting in prominent myocardial trabeculae, deep intra-trabecular recesses, and decreased cardiac function. It has been proposed that LVNC results from arrest of the compaction process during the second month of embryological development.
