Noncompaction cardiomyopathy (NCCM) is characterized by heavy trabeculations, deep intertrabecular recesses, and a thickened myocardium consisting of a thin compacted and a thick non-compacted layer.1 Previously an "unclassified cardiomyopathy", NCCM is now recognized as a congenital cardiomyopathy that can occur with other congenital heart diseases or as isolated cases. Although a rare condition, isolated NCCM shares a genetic profile with hypertrophic cardiomyopathy and dilated cardiomyopathy, leading to a strong familial association of heart failure, embolic events, and arrhythmias.
