Abstract:
Described herein is a 53-year-old man who underwent resection of a fusiform aneurysm of the ascending aorta, and excision of a congenitally malformed stenotic unicuspid aortic valve. Examination of the wall of the aortic aneurysm disclosed classic features of syphilis. Although some degree of pure aortic regurgitation is common in patients with aortic syphilis, the presence of associated aortic valve stenosis, such as occurred in this patient, has been mentioned in only 4 previous publications, none of which included morphologic examination of the ascending aorta or aortic valve.

The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
