A Case of Unruptured Aneurysm of the Sinus of Valsalva

Abstract

A 36-year-old woman was admitted because of dyspnea on exertion and palpitations, during follow-up for ventricular septal defect since age 5. Physical examination revealed a grade IV/VI ejection systolic murmur at the second left intercostal space. Echocardiogram failed to recognize an unruptured aneurysm of the sinus of Valsalva protruding into the right ventricle which was seen on right ventriculogram (type I of Konno). Surgical treatment was successfully performed. Right ventriculography was much more effective rather than echocardiography in this case.
