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 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...

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 کاملPremature valve closure in patients with a mitral Starr-Edwards prosthesis and aortic incompetence.
A mitral Starr-Edwards ball valve has, in three patients with concomitant aortic incompetence, permitted recognition of intermittent premature valve closure by auscultation and this has been documented by phonocardiograms. In two instances the observations were confirmed during cardiac catheterization. The features of premature Starr valve closure are described and the mechanism is discussed.
