Failure of Beall mitral valve prosthesis

Advantages of the Beall valve prosthesis.

Followup of 29 patients with a Beau mitral valve prosthesii has shown important advantages over the KayShiiey valve. No late deaths and no emboli were noted during an average 14 month (range 8 to 27 months) follewup. Mitral insufficiency was not noted clinically or by angiography. Hernodynamic studies in nine patients 16 months postoperation showed improvement. Although all patients had evidenc...

Haemolysis related to mitral valve replacement with the Beall valve prosthesis.

Ten-year pathological study of Beall mitral valve prostheses.

Detailed pathological studies are reported on 20 cloth-covered Beall mitral valve prostheses, which had to be removed for valve failure nine months to 10 years after implantation. Results in all patients except one indicated that there was a progressive and persistent granulomatous reaction that continued up to at least 10 years. Although the rate of tissue ingrowth into the valve decreased wit...

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 ...

Fulminant thrombosis of mechanical mitral valve prosthesis.

In patients with prosthetic heart valves non-cardiac surgery may require temporary discontinuation of oral anticoagulation. Although the risk of valve related thromboembolic complications may generally be only slightly increased during the short perioperative period, in the presence of certain risk factors, replacement of oral anticoagulation with heparin is recommended. In the presented patien...
