|March 1, 1979
Summary
The Beall mitral prosthesis showed an 11.34% early mortality and 8.14% thromboembolic complications in 97 patients undergoing mitral valve replacement. Most survivors achieved good functional capacity.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
Context:
- Mitral valve replacement is a critical procedure for patients with severe mitral regurgitation or stenosis.
- The Beall mitral prosthesis (103, 104 & 105 series) was evaluated between 1970 and 1973.
Purpose:
- To assess the early and late outcomes of isolated mitral valve replacement using the Beall mitral prosthesis.
- To report on complications including mortality, thromboembolism, prosthetic malfunction, and hemolysis.
Summary:
- A total of 97 patients underwent isolated mitral valve replacement with the Beall prosthesis.
- Early surgical mortality within 30 days was 11.34%.
- Among 86 survivors, 8.14% experienced thromboembolic complications, and 20 late deaths occurred. Other complications were also noted.
Impact:
- The study provides historical data on the performance of an early mechanical mitral valve prosthesis.
- Understanding these outcomes informs the development and selection of prosthetic devices for valvular heart disease.
- A significant majority of late survivors (92.42%) demonstrated good functional status (NYHA Class I or II).
