Non-compaction du ventricule gauche : diagnostic et prise en charge.

Isolated left ventricular non-compaction (LVNC) is a congenital disorder characterized by prominent myocardial trabeculations and deep intertrabecular recesses. Although LVNC is diagnosed by echocardiography and cardiac magnetic resonance, there is no evidence-based imaging diagnostic criteria. Affected individuals are at risk of left ventricular failure, life-threatening arrhythmias and cardio-embolism. The diagnosis may be difficult in the atypical forms. The management remains controversial and depends on the clinical manifestations. Familial forms exist, ordering for genetic counseling. The aim of this article is to optimize the knowledge and the management of LVNC by reminding the diagnostic criteria used.
