Thromboembolism after Starr valve replacement.
One hundred and six patients who left hospital after Starr-Edwards ball valve replacements have beenfollowedfor a period of 6 months tO 4 years. All patients were maintained on oral anticoagulant therapy so that a prothrombin ratio of approximately I 7:I was attained. Four patients suffered minor nose bleeds. During the period offollow-up there have been 4 patients who have suffered embolic phe...
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 کاملIntravascular haemolysis after valve replacement: comparative study between Starr-Edwards (ball valve) and Björk-Shiley (disc valve) prosthesis.
Seventy-four patients with single prosthetic valves (Björk-Shiley or Starr-Edwards) in the mitral or aortic position and 18 controls with rheumatic valvar heart disease were investigated for evidence of intravascular haemolysis. Serum lactate dehydrogenase (LDH) was used as the most sensitive indicator of haemolysis. Raised concentrations were found in a third of 39 patients with Björk-Shiley p...
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 کاملPhonocardiographic method of assessing changes in left ventricular function after Starr-Edwards replacement of aortic valve.
A phonocardiographic method is described for measuring the time taken by the ball of a Starr-Edwards prosthesis to move to the apex of the cage at the onset of left ventricular ejection, and from this its acceleration can be derived. The acceleration is conspicuously increased in post-ectopic beats and in exercise, but is unaffected by posture and tachycardia induced by atropine or ventricular ...
