Summary
The Starr-Edwards 6120 prosthetic valve demonstrated a 73% survival rate at 12 years in 230 patients undergoing mitral valve replacement. Valve-related complications were similar to other prostheses, with a long follow-up period analyzed.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
- Clinical Outcomes Research
Background:
- The Starr-Edwards 6120 prosthesis is a mechanical heart valve used for mitral valve replacement.
- Long-term data on the safety and efficacy of this specific model are crucial for clinical decision-making.
Purpose of the Study:
- To evaluate the long-term outcomes of mitral valve replacement using the 6120 Starr-Edwards prosthesis.
- To assess operative mortality, survival rates, and valve-related complications.
Main Methods:
- A retrospective analysis of 230 patients who underwent mitral valve replacement with the 6120 Starr-Edwards prosthesis over 12 years.
- Follow-up data were collected to determine survival rates and incidence of complications like thromboembolism.
Main Results:
- Operative mortality was 6.5%.
- Estimated late survival rates were 80% at 5 years and 73% at 12 years.
- Valve-related deaths accounted for 38% of late deaths. Thromboembolism occurred at 4.7% per patient-year.
Conclusions:
- The 6120 Starr-Edwards prosthesis shows acceptable long-term survival and complication rates comparable to other mechanical valves.
- This study provides extensive follow-up data for this specific prosthetic valve model.
