Mitral Ball-Valve Prosthesis
REPLACEMENT of nonfunctioning valves is a significant recent advancement in the correction of cardiac valvular disease. The most widely used artificial device replacing the mitral valve is the Starr-Edwards ballvalve prosthesis.' Its effectiveness was shown in recent reports by the marked clinical improvement in properly selected patients.2 However, cardiologists and cardiac surgeons are faced ...
متن کاملMitral replacement: clinical experience with a ball-valve prosthesis. Twenty-five years later.
The purpose of this report is to review the results of mitral valve replacement since a first report in the Annals of Surgery in 1961, in order to determine the relative importance of new valve designs versus other surgical variables. The continued use of the silastic ball valve in its 1966 configuration (Model 6120), by providing a comparative data base for other new prosthetic valves, allows ...
متن کاملMitral valve replacement with Alvarez prosthesis: long-term results.
Since the introduction of the Alvarez mitral valve prosthesis in 1964 it has been used clinically in Leeds General Infirmary because it was thought that it would produce better haemodynamic results than the other prosthetic valves. The aim of this study is to present the longterm results in patients who had this prosthesis inserted in the mitral valve position, and to show the high incidence of...
متن کاملRight sided heart evaluation after successful mitral valve replacement.
Introduction: It is well-documented that right-sided heart dysfunction and significant tricuspid valve regurgitation (TVR) have adverse effects on patient outcomes after left-sided heart valve surgery. Therefore, the evaluation of right ventriclular (RV) function and TR severity in patients who had undergone mitral valve replacement (MVR), associated with/without concomitant su...
متن کاملHaemolysis after mitral valve replacement with the Björk-Shiley and the Lillehei-Kaster disc valve prosthesis.
The present study reports on the incidence and degree of intravascular haemolysis in 33 patients with Björk-Shiley tilting disc prosthesis and in 34 patients with Lillehei-Kaster pivoting disc valve prosthesis in the mitral position examined 12 to 24 months after the operation. Serum haptoglobin, serum lactate dehydrogenase, serum bilirubin, and haemoglobin estimations were performed. Significa...
