Valve type and size associated with hemolysis severity; leaves open relevance to contemporary mechanical prostheses.
Does the type and size of Starr-Edwards aortic ball valves influence the degree of erythrocyte destruction?
Valve type (metallic vs silastic) and size are the most important factors in producing hemolysis in patients with Starr-Edwards aortic ball valves.
Myhre et al. (1970) studied this question.
