Left ventricular non-compaction (LVNC) cardiomyopathy is a heterogeneous and relatively rare group of heart disease with the dominant feature being marked non-compactness of the myocardial luminal layer of some left ventricular segments. Its diagnosis is established by echocardiography, with the finding dominated by abnormal, appreciably prominent trabecularization of the left ventricular myocardium, particularly left ventricular postero-lateral segments with deep recessions.
Treatment is governed by the same rules as with dilated cardiomyopathy.
