Our experience with the Carpentier-Edwards bioprosthesis
Insights
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.
Abstract:
Sixty Carpentier-Edwards porcine valve bioprostheses stabilized with glutaraldehyde were implanted in 55 patients with acquired and congenital heart disease. The follow-up period ranged between 1 and 12 months. There were 3 hospital deaths (5%) and 2 late deaths (4%) in 24 mitral, 24 aortic, 5 mitral-aortic, 1 tricuspid and 1 pulmonary valve replacements. All patients were anticoagulated from the second postoperative day onwards for a period of 3 months after which those with sinus rhythm had their anticoagulants withdrawn. Paravalvular leakage led to re-operation in 3 cases (4%). No valve failure due to cusp rupture was encountered and no thromboembolic complications have occurred. Thirty-three patients were studied postoperatively by non-invasive methods and the results are presented.
