Echocardiographic features of aortic ball valve prosthesis malfunction

Phonocardiogram of the ball-and-cage aortic valve prosthesis.

Fixation 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...

The Variable Echocardiographic Features in Aortic Valve

The echocardiographic abnormalities in five cases of aortic valve endocarditis are described and are correlated with the anatomical appearance of the valve at the time of aortic valve replacement. These echocardiographic findings are compared with those which have been reported previously in this condition. Thickening of the aortic leaflets in systole or multiple linear or coalescent aortic val...

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 ...
