Giant pseudoaneurysm of the right sinus of Valsalva

A pseudoaneurysm of the sinus of Valsalva is a very rare cardiac abnormality. We report a surgical case of the pseudoaneurysm of the right sinus of Valsalva in a 77-year- old woman. The histopathological examination of the resected aneurysmal wall revealed that it was a pseudoaneurysm without any specific inflammatory changes. Although we cannot identify the clear cause of the formation of the pseudoaneurysm, we believe it may have been a type of spontaneous rupture of the sinus of Valsalva.
