Congenital left ventricular subaortic aneurysm in an asymptomatic child.

A newborn was referred to our department, due to the presence of a cardiac murmur. Echocardiographic study showed a small membranous ventricular septal defect and a yuxta-aortic mass. In the follow-up, patient remained asymptomatic, ventricular septal defect closed, and yuxta-aortic mass increase in size with somatic growth.

An asymptomatic 1-month-old girl was studied in another institution because of the presence of a cardiac murmur, and referred to our center for further evaluation as a result of tricuspid valve abnormalities detected in the echocardiographic study. Echocardiography revealed a very redundant, thin, freely mobile structure in the right atrium, moving rapidly in (systole) and out (diastole) of the right ventricle through the tricuspid orifice. It arose from near the border of the inferior vena cava and attached to the atrial wall close to the coronary sinus ostium, suggesting an unusually prominent Chiari's network.
