Calcific stenosis of a glutaraldehyde-treated porcine bioprosthesis in the aortic position
MH Gordon, MB Walters, P Allen and JD Burton
The porcine xenograft bioprosthesis is used widely at the present time,
although its long-term durability is still being evaluated. Calcification
resulting in stenosis of the glutaraldehyde-treated bioprosthesis has been
reported infrequently. In the patient described herein, severe calcific
stenosis of a porcine xenograft in the aortic position occurred 45 months
after implantation. This report emphasizes the life-threatening and rapidly
progressive nature of this complication in the long-term survivor after
valve replacement.
