Erythrocyte Destruction in Different Types of Starr-Edwards Aortic Ball Valves
Increased destruction of red blood cells follows the insertion of ball valves into the heart in most cases. Usually, hemolysis is slight, but in some patients uncompensated hemolytic anemia develops. To study the influence on hemolysis of the mechanical properties of the prostheses, the degree of erythrocyte destruction was evaluated in patients with Starr-Edwards aortic prostheses of different...

متن کاملClinical significance of multiple systolic clicks from Starr-Edwards prosthetic aortic valves.
The use of echocardiography, phonocardiography, and spectroanalysis has enhanced the ability to detect prosthetic valve dysfunction even before the onset of symptoms in many patients. Reduction in the intensity of the opening and closing clicks and the appearance of new murmurs have been the most frequently reported observations in predicting prosthetic valve dysfunction. Simultaneous echocardi...
متن کاملHaemolysis with Björk-Shiley and Starr-Edwards prosthetic heart valves: a comparative study.
Slater, S. D., Saflam, I. A., Bain, W. H., Turner, M. A., and Lawrie, T. D. V. (1974). Thorax, 29, 624-632. Haemolysis with Bjork-Shiley and Starr-Edwards prosthetic heart valves: a comparative study. A comparison was made of the haemolytic complications in 85 patients with two different types of Starr-Edwards cloth-covered ball and cage prosthesis with those in 44 patients with the Bjork-Shile...
متن کاملCineangiographic studies in patients with Starr-Edwards aortic valves.
RECENT REPORTS of postoperative clinical and cardiac catheterization studies in patients after replacement of their aortic valves with a ball-valve prosthesis have included adequate clinical and hemodynamic measurements both at rest and during exercise.'-6 There is, however, little information regarding the competency of these valves as determined angiographically, since aortic root cineangiogr...
