Cineangiographic 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...
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 کاملThe Starr-Edwards valve.
This report reviews the results obtained with the current models of the Silastic ball valve, classifying the experience with the mitral and aortic models into the periods (formula: see text) before and after 1973. Valve failure is defined according to the Stanford method and includes any valve-related death or complication necessitating valve removal (there have been no mechanical failures). Co...
متن کاملErythrocyte 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...
