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. A transesophageal echocardiography was carried out, showing a fibrotic and dyskinetic left ventricular subaortic aneurysm of 19×18 mm. Given that the patient remained asymptomatic, a conservative approach was adopted. Congenital left ventricular subaortic aneurysm is an infrequent entity, and rupture, endocarditis, coronary compression, 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.
