Valve replacement in children
Insights
The St. Jude prosthetic valve shows excellent performance in pediatric patients, with a 90% event-free survival rate up to 5 years. Anticoagulation was not essential for preventing complications in this study.
Area of Science:
- Cardiology
- Pediatric Cardiac Surgery
- Biomaterials Science
Background:
- Prosthetic heart valves are crucial for treating pediatric valvular heart disease.
- Long-term durability and safety in pediatric populations remain critical considerations.
- The St. Jude prosthetic valve is a mechanical option used in pediatric cardiac surgery.
Purpose of the Study:
- To evaluate the early and mid-term performance of the St. Jude prosthetic valve in pediatric patients.
- To assess the incidence of complications and survival rates following valve replacement in children.
- To compare the efficacy of different anticoagulation strategies in pediatric patients with prosthetic valves.
Main Methods:
- Retrospective review of 81 pediatric patients (aged 3-15 years) who underwent valve replacement.
- Inclusion of mitral, aortic, and double valve replacements performed between February 1979 and August 1984.
- Actuarial analysis to determine event-free survival and complication rates.
Main Results:
- Early mortality was 3.7% in the cohort.
- Actuarial analysis demonstrated 90% event-free survival up to 5 years post-implantation.
- No significant difference in complication rates was observed between patients receiving warfarin, aspirin, or no anticoagulation therapy.
Conclusions:
- The St. Jude prosthetic valve is well-suited for pediatric use, avoiding the early degeneration seen with heterograft valves.
- Anticoagulation therapy was not essential for managing complications in this pediatric cohort.
- The valve offers a durable and safe option for pediatric valvular heart disease treatment.
Abstract:
The performance of the St. Jude prosthetic valve is reviewed in 81 patients aged 3 to 15 years. All 66 mitral (2 re-replacements), 8 aortic and 9 double valve replacements between February 1979 and August 1984 are included. The early mortality was 3.7% and actuarial analysis shows a 90% event free survival up to 5 years. Anticoagulant therapy was used in most patients, but comparison between groups receiving warfarin or aspirin or no therapy reveals no differences in the complication rate. The valve is well suited for use in children since the early degeneration seen with heterograft valves does not occur, and anticoagulation is not essential.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
