Cardiac magnetic resonance imaging provides detailed morphological assessment and high diagnostic accuracy for left ventricular noncompaction cardiomyopathy, overcoming limitations of echocardiography.
Supports detailed CMRI assessment for left ventricular noncompaction; leaves open routine adoption pending higher-level evidence.
Left ventricular noncompaction cardiomyopathy is a very rare condition, yet believed to be often overlooked. It is thought to be caused by the developmental arrest in embryogenesis and characterized by an increase in the noncompacted, trabeculated myocardium adjacent to compacted myocardium in the left ventricular. The clinical presentations of this type of cardiomyopathy are of variable severity. Echocardiography used to be the diagnostic modality, but recent reports suggest that cardiac magnetic resonance imaging has higher sensitivity and specificity by showing a ratio of the noncompacted myocardium to compacted myocardium of >2.3.
