Valve dysfunction of the cloth-covered Starr-Edwards ball valve.
BACKGROUND Between June 1968 and March 1977, Starr-Edwards cloth-covered ball valves were used for valve replacement on a routine basis. METHODS AND RESULTS Among the 66 operative survivors who underwent an isolated aortic or mitral valve replacement, 20 patients required reoperation 22 times because of valve dysfunction, thromboembolic complication, paravalvular leakage, hemolytic anemia, an...
متن کاملCloth destruction and haemolysis with totally cloth-covered Starr-Edwards prostheses.
Four cases are described in which totally cloth-covered Starr-Edwards valves (model 2300) had to be removed. All were causing significant haemolysis, two in the absence of a peripheral leak. The principal operative finding was destruction of the Dacron covering the struts. Following replacement of these prostheses there was complete resolution of signs and symptoms. The possible causes of haemo...
متن کاملImpaired function of cloth-covered Starr-Edwards mitral valve prosthesis. Detection by phonocardiography.
was suspected because of phonocardiographic abnormalities. A prolonged interval from aortic closure to opening of the mitral ball suggested an impediment to movement of the ball. This was confirmed by catheterization and cinefluorography. At autopsy the impaired ball movement was found to be due to thrombus buildup on the outflow face of the mitral valve orifice. It is suggested that frequent p...
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...
متن کاملThrombo-embolic complications of the cloth-covered Starr-Edwards prostheses No. 2300 aortic and No. 6300 mitral.
The thrombo-embolic complications of the cloth-covered Starr-Edwards prostheses No. 2300 aortic and No. 6300 mitral followed for an average of 14 months in 155 patients are reviewed. There was a high incidence of early fatal and disabling thrombo-embolus in patients 'having mitral valve replacement. Late emboli were more common after aortic valve replacement. Anticoagulant control was unsatisfa...
