Our experience with the Carpentier-Edwards bioprosthesis
Scandinavian Journal of Thoracic and Cardiovascular Surgery
|January 1, 1979
Summary
This study evaluated Carpentier-Edwards porcine bioprosthetic valves in 55 patients, finding no thromboembolic complications or cusp ruptures within a 12-month follow-up. Paravalvular leakage required re-operation in a small percentage of cases.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
- Clinical Medicine
Background:
- Acquired and congenital heart diseases necessitate valve replacement.
- Porcine bioprosthetic valves offer an alternative to mechanical prostheses.
- Glutaraldehyde stabilization is a common method for preserving bioprosthetic tissue.
Purpose of the Study:
- To assess the early clinical performance and safety of Carpentier-Edwards porcine valve bioprostheses.
- To evaluate complications such as paravalvular leakage and thromboembolism.
- To present postoperative findings from non-invasive assessments.
Main Methods:
- Implantation of 60 Carpentier-Edwards porcine valve bioprostheses in 55 patients.
- Follow-up ranging from 1 to 12 months post-surgery.
- Postoperative anticoagulation management and non-invasive patient evaluation.
Main Results:
- Low rates of hospital (5%) and late (4%) mortality observed.
- No instances of valve failure due to cusp rupture.
- No thromboembolic complications occurred; 4% experienced paravalvular leakage requiring re-operation.
Conclusions:
- Carpentier-Edwards porcine bioprosthetic valves demonstrate acceptable early safety and efficacy.
- The absence of thromboembolic events is a significant finding.
- Paravalvular leakage remains a potential complication requiring monitoring and management.
