A dissecting aneurysm of the sinus of Valsalva involving the interventricular septum in a patient with syphilis and a quadricuspid aortic valve

Aneurysms of the sinus of Valsalva are rare, with dissecting aneurysms of the sinus of Valsalva that extend into the interventricular septum being even more rare. This report describes a young patient with syphilis and a quadricuspid aortic valve who experienced a spontaneously dissecting aneurysm of the sinus of Valsalva and the basal interventricular septum.
