Aortic insufficiency produced by stent-graft displacement.

The following case report describes an unusual example of aortic valve damage caused by iatrogenic stent-graft rupture (disconnection of the proximal uncovered part of a stent-graft) during delivery of a proximal extension, resulting in the displacement of a stent-graft wire to the aortic root. The wire was extracted under cardiopulmonary bypass, using circulatory arrest, and the damaged aortic valve replaced by a mechanical valve.
