At the Niigata University Hospital, various kinds of prosthetic valves such as the Starr-Edwards nonclothand cloth-covered, Bjork-Shiley tilting disc, and Carpentier-Edwards porcine valves, have been used from September, 1965 to March, 1979 for replacement of diseased valves on 176 patients. The patients with Starr-Edwards nonclothand cloth-covered ball valves showed survival rates of 90 and 84...

Sinus of Valsalva aneurysm is a rare anomaly, most often caused by a congenital absence of muscular and elastic tissue in the aortic wall of the sinus of Valsalva. It was first described in 1938. The incidence is higher in eastern than western populations. Various surgical repair techniques have been reported with good results. In this case, a 61 years old man, with history of aortic valve repl...

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...

C atheter assessment of Starr-Edwards prosthetic aortic valve stenosis requires simultaneous recording of left ventricular (LV) and aortic pressures. Passage of conventional Dacron catheters across mechanical valves can damage the mechanism and induce valvar incompetence. The alternative Bockenbrough procedure requires atrial septal puncture with potential lethal complications. The availability...

Ö o ( c p e fi ( ( t d v ( l With the advent of the Starr-Edwards mechanical mitral and aortic valves in the 1960s, the surgical era of the treatment of cardiac valvular disease began in earnest. Although considered definitive, valve replacement surgery effectively represents an exchange of the pathophysiology of severe valvular dysfunction for the diseases and complications associated with pro...

The long term performance characteristics of the 2400 and 1260 series of Starr-Edwards aortic prostheses were investigated by a follow up study of clinical outcome of 327 patients discharged from hospital with isolated aortic valve replacement. Follow up lasted for up to 10 years and was based on 1616 patient-years. The 2400 series cloth covered tracked valve was implanted in 182 patients from ...

Total mitral valve replacement was first successfully accomplished by Starr and Edwards (1961) using a ball valve prosthesis. We have adopted their method for patients in whom the pathological changes make it impossible to obtain a mobile anterior mitral leaflet due to calcifications or shortened fused chordae tendineae. This paper describes an instrument that holds the ball valve prosthesis in...
