The chance finding of an aneurysm of the right sinus of Valsalva in an 11-year-old child with a ventricular septal defect and a pericardial effusion.

Ventricular septal defects can occur as part of other congenital cardiac malformations or as an isolated finding. Aneurysms of the sinus of Valsalva are rare, most commonly involving the right or noncoronary sinuses. They can be congenital or acquired through infection, trauma, or degenerative diseases. They frequently co-exist with ventricular septal defects, aortic valve dysfunction, or other cardiac abnormalities. More commonly, sinus of Valsalva aneurysms are diagnosed after the clinical sequelae of rupture. Several etiologic factors may lead to the development of pathologic pericardial effusion and the detection of pericardial effusion was one of the first applications of echocardiography to gain widespread acceptance. We present a case of a chance finding of an aneurysm of the right sinus of Valsalva in an 11-year-old Italian child with a ventricular septal defect and a pericardial effusion.
