A Surgical Case of Sinus of Valsalva Aneurysm Diagnosed by Cardiac Multidetecter-Row Computed Tomography / 日本心臓血管外科学会雑誌

ABSTRACT

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. However it is difficult to make a definite diagnosis because of cardiac beating artifact. Cardiac multidetecter-row CT demonstrated an aneurysm of the noncoronary sinus of Valsalva connected to the sinus with a small aperture. Aortic valve replacement and patch closure were performed. The postoperative course was uneventful and follow-up CT showed thrombus formation in the sinus Valsalva aneurysm. Cardiac multidetecter-row CT was useful for accurate diagnosis of aortic root disease.
