title: Severe hemolysis due to cloth wear 23 years after aortic valve replacement on a Starr-Edwards ball valve model 2320.
abstract: Despite iron substitution therapy, a patient developed severe hemolytic anemia 23 yr after insertion of a cloth-covered Starr-Edwards model 2320 aortic valve prosthesis. The prosthesis showed no sign of significant dysfunction. Upon removal, it showed extensive cloth wear on the inner surface of all three struts; one strut was completely denuded of its cloth covering. Hemolysis immediately resolved after replacement with a St Jude aortic prosthesis.
