Disappearance of opening sound of Starr-Edwards mitral valve due to valvular detachment.

The 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...

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...

Spread of the "mitral" Sound over the Chest. a Study of Five Subjects with the Starr-edwards Valve.

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...

Analysis of dynamics of mitral Starr-Edwards valve prosthesis using reflected ultrasound.

The speed of closure of the mitral valve during diastole, as recorded by ultrasonocardiography, is reduced in patients with mitral stenosis. A pattern of movement similar to that of severe mitral stenosis is seen in recordingsfrom patients with normally functioning mitral Starr-Edwards prostheses. Simultaneous ultrasound recordings of ball and cage movements show that the prosthetic valve remai...
