Letter to the Editor 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 yuxtaaortic mass increase in size with somatic growth. A transesophageal echocardiography was carried out, showing a fibrotic and dyskinetic left ventricular subaortic aneurysmof19×18mm.Given thatthepatient remainedasymptomatic, aconservativeapproachwas adopted. Congenital leftventricular subaorticaneurysmisaninfrequent entity,andrupture,endocarditis,coronarycompression,thromboembolism,arrhythmias and aortic insufficiency are some of its complications, but, as in our patient, if aneurysm is not associated with complications, patient is asymptomatic, and aneurysm growth is not very important, a conservative approach can be adopted, with a close surveillance. © 2009 Elsevier Ireland Ltd.
