Noncompaction-like membranous structure in left ventricle.

A 22-day-old boy born to a 21-year-old gravida 1, para 1 mother was admitted to our hospital for routine newborn examination. On physical examination, any clinical abnormality or malformations were not observed except 1/6 systolic murmur. A well-demarcated membranous structure was confirmed by echocardiography which was starting from left ventricular apex, extending to the mitral chords including papillary muscles in apical four-chamber and parasternal long-axis examination. This structure was considered as a variant of left ventricular noncompaction. The patient is still being followed up in our pediatric cardiology department.
