Left ventricular noncompaction.

摘要

Left ventricular noncompaction is a rare cardiomyopathy characterized by prominent ventricular hypertrabeculation. Here, we discuss the case of a 30-year-old man who presented with rapidly conducted atrial fibrillation. The images we present demonstrate appearances characteristic of this cardiomyopathy, with prominent trabeculations and an end-diastolic noncompacted to compacted myocardial thickness ratio of more than 2 noted on echocardiography and magnetic resonance imaging.
