Left ventricular noncompaction highlighted by three-dimensional and speckle tracking echocardiography
DOI: 10.31744/einstein_journal/2022AI6853
Left ventricular noncompaction (LVNC) is a relatively new and heterogeneous cardiomyopathy, first reported by Chin et al. in 1990.() It is characterized by prominent ventricular trabeculations, intratrabecular recesses and a bi-layered myocardium, composed of compacted and noncompacted layers.(,) Left ventricular noncompaction may be an isolated finding or associated to other cardiomyopathies, metabolic disorders and congenital heart diseases.() It is believed to result from failure of ventricular compaction in the embryogenic phase, with increasing evidence of a genetic component.()
Since its first description, much has been learned about this disease, but there are some limitations for its diagnosis. Cardiac magnetic resonance imaging is considered the gold standard for diagnosis of LVNC, but echocardiography remains the first line imaging modality due to its availability and cost-effectiveness.
