The genetically determined role of the compact myocardial layer in excessively trabeculated left ventricular noncompaction
Background: Left ventricular excessive trabeculation (LVET) ranges from preserved ejection fraction (EF) morphology to reduced EF Noncompaction cardiomyopathy. Emerging evidence indicates that EF reduction is more strongly associated with thinning of the Compact myocardial layer (CL) than with trabeculation alone, alth...
