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...
متن کاملMalfunction of the mitral valve prosthesis (Cutter-Smeloff). Clinical and hemodynamic observations in three cases.
Three cases of intermittent obstruction of the mitral prosthesis (Cutter-Smeloff) due to ball variance have been reported. The typical findings were marked variation in the arterial pulse and the intensity of the mitral closing sound and intermittent absence of the opening click. The phonocardiography revealed varying intervals from aortic closing sound to the opening click (A2 OC interval). He...

متن کاملResults after mitral valve replacement with cloth-covered Starr-Edwards prostheses (models 6300, 6310/6320, and 6400).
The actuarial survival and thromboembolic rates for the three types of cloth-covered Starr-Edwards mitral prostheses, models 6300, 6310/6320, and 6400 followed 6, 5, and 2 years, respectively, were not significantly different throughout the years they were followed. The combined cumulative survival and thromboembolic proportion at 5 years for these prostheses were 71 and 66 per cent, respective...
متن کاملPathology of heart valve replacement surgery: autopsies of 62 patients with Starr-Edwards prostheses.
Hemorrhage in the atrioventricular conduction system and myocardial necrosis commonly occur in the first week after valve replacement. Later, thrombosis on the prosthesis and infarcts in other organs become important but developing or persistent myocardial damage continuously menaces. Occlusion of small vessels, especially by embolism of foreign material, may contribute to the development of th...
