A fenestrated aortic valve contributing to iatrogenic aortic insufficiency post mitral valve replacement

A case of an unusual local complication of cardiac valvular surgery is presented. Distortion of the geometry of the aortic valve base by a prosthetic mitral valve sewing ring allowed aortic insufficiency through the aortic valveʹs central orifice, as well as through an aortic valve cusp fenestration. During the 6 years after valve surgery, this patient developed chronic left heart failure contributed to by the aortic insufficiency and eventually, at age 65, required cardiac transplantation. Surgeons and pathologists should be aware of this unusual local complication of cardiac valve surgery, as it may have serious consequences.
