Aortic valve destruction and pseudoaneurysm of the sinus of Valsalva associated with infective endocarditis.

: We report the successful surgical treatment of a case of aortic valve destruction and pseudoaneurysm of the sinus of Valsalva associated with infective endocarditis (IE) in an 80-year-old woman. Multidetector-row computed tomography revealed an abnormal cavity in the left posterior aortic root. We had made the diagnosis of the aortic valve destruction and saccular pseudoaneurysm of the sinus of Valsalva associated with IE. Aortic valve replacement and patch plasty of the left sinus of Valsalva was performed successfully. A histopathologic examination of the resected aortic valve leaflet revealed inflammatory changes consistent with IE. We describe the surgical technique used in this rare case of pseudoaneurysm of the sinus of Valsalva resulting from IE.
