Acute dysfunction of Starr-Edwards mitral prostheses.
Four cases of acute dysfunction of Starr-Edwards mitral prostheses are recorded. The patients presented with sudden dyspnoea 4 to 18 months after apparently successful mitral valve replacement. The prosthetic valve dysfunction was caused by thrombus on the bare metal cage of the prosthesis. No warning thromboembolic phenomena had been recorded. Urgent replacement of the valve resulted in the su...
متن کاملPathology of heart valve replacement surgery: autopsies of 62 patients with Starr-Edwards prostheses.
Hemorrhage in the atrioventricular conduction system and myocardial necrosis commonly occur in the first week after valve replacement. Later, thrombosis on the prosthesis and infarcts in other organs become important but developing or persistent myocardial damage continuously menaces. Occlusion of small vessels, especially by embolism of foreign material, may contribute to the development of th...
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 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 کاملFunctional results with aortic ball valve prostheses (Starr-Edwards) followed for two to three years.
It is now believed that aortic insufficiency and calcific aortic stenosis must be treated with total valve replacement. Until recently this was performed with the aid of prostheses of teflon and similar materials. Even if the short-term results were promising, follow-up studies revealed a high percentage of breakdown of these prostheses (Bjork, Cullhed, and Lodin, 1963; Larson and Kirklin, 1964...
