A 69-year-old man was admitted to our hospital due to cardiomegaly on plain chest radiography. He did not have any history of chest pain, trauma or fever of unknown origin. Echocardiography showed severe aortic valve regurgitation. Standard enhanced computed tomography(CT)showed a localized dissection or an aneurysm of the noncoronary sinus of Valsalva.

Three-dimensional CT was useful to detect the association between the arch aneurysm and neck vessels. Graft replacement, from the distal arch to the descending thoracic aorta, was
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
