Why the study?
Does the type of aortic ball-valve prosthesis affect the severity of hemolysis in patients after aortic valve replacement?
Does the type of aortic ball-valve prosthesis affect the severity of hemolysis in patients after aortic valve replacement?
Hemolysis is significantly more severe in patients with Starr-Edwards aortic ball-valve prostheses compared to Magovern or Cutter valves.
No takes yet. Share an insight, caveat, or question.
Starr-Edwards valves were associated with more severe hemolysis; leaves open whether prosthesis design affects hemolytic risk in modern aortic replacement.
Eyster et al. (1971) studied this question.
