Summary
Combined mitral and aortic valve replacement using Björk and Starr prostheses showed a 6-year survival of 84%. Post-operative complications were low, with survivors experiencing functional improvement.
Area of Science:
- Cardiovascular Surgery
- Prosthetic Valve Design
- Clinical Outcomes Research
Context:
- Between 1970 and 1976, 75 patients underwent combined mitral and aortic valve replacement.
- Prostheses used included the Björk prosthesis (aortic) and Starr 6120 (mitral).
- Follow-up ranged from 12 months to a mean of 3.72 years.
Purpose:
- To evaluate the early and late outcomes of combined mitral and aortic valve replacement.
- To assess survival rates and post-operative complications.
- To investigate the influence of pre-operative factors on mortality.
Summary:
- Early and late mortality rates were 5.3% and 8.4%, respectively.
- Actuarial survival projected 16% mortality at 6 years, comparable to mitral valve replacement alone.
- Only 3 embolic complications were observed; heart failure, heart size, and hemodynamics did not significantly impact mortality.
Impact:
- Survivors demonstrated functional improvement, with significant reductions in pulmonary arterial and capillary wedge pressures.
- Radiological heart size was significantly reduced post-operatively.
- This study provides insights into the long-term efficacy and safety of combined valve replacement procedures using specific prostheses.
