Key Points

To document a case of severe hemolytic anemia caused by mechanical cloth wear on a ball-valve prosthesis decades after aortic valve replacement.
Evaluated a patient presenting with severe hemolytic anemia refractory to iron substitution therapy 23 years after aortic valve replacement with a cloth-covered Starr-Edwards model 2320 prosthesis.
Performed surgical valve explantation, macroscopically assessed the prosthesis struts, and replaced the device with a St. Jude aortic valve.
The explanted valve demonstrated extensive cloth wear along the inner surface of all three struts, with one strut entirely stripped of its cloth covering, despite exhibiting no prior hemodynamic dysfunction.
Hemolysis resolved immediately following replacement of the damaged device with a St. Jude aortic prosthesis.

Implication

Cloth wear on older Starr-Edwards aortic valve prostheses can cause severe hemolytic anemia decades after implantation, which resolves upon valve replacement.

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.
