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...
متن کاملDiastolic murmurs in the presence of Starr-Edwards mitral prosthesis.
Diastolic murmurs associated with the Starr-Edwards mitral prosthesis have not been described previously. In this report, five patients with mitral prostheses are described in whom apical mid-diastolic and presystolic murmurs resulted from two different causes. Three patients had clots obstructing the prosthetic orifice. The other two had normally functioning protheses and moderately severe aor...
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 کاملImpaired function of cloth-covered Starr-Edwards mitral valve prosthesis. Detection by phonocardiography.
was suspected because of phonocardiographic abnormalities. A prolonged interval from aortic closure to opening of the mitral ball suggested an impediment to movement of the ball. This was confirmed by catheterization and cinefluorography. At autopsy the impaired ball movement was found to be due to thrombus buildup on the outflow face of the mitral valve orifice. It is suggested that frequent p...
