Functional 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...
متن کاملValve 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 کاملFixation of aortic ball valve prosthesis (Starr-Edwards).
The technique of fixation of a ball valve prosthesis in the area of the non-coronary cusp by bringing the sutures from the collar of the prosthesis out through the wall of the aorta and tying them over strips of dacron has been discussed by Starr, Edwards, McCord, and Griswold (1963), and advocated by Effler, Groves, and Favaloro (1964). We have never in our first 100 operated cases seen a leak...
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 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...
