Tricuspid valve replacement in children.

M Pasque, W G Williams, J G Coles

    The Annals of Thoracic Surgery
    |August 1, 1987
    PubMed
    Summary

    Pediatric tricuspid valve replacement using prosthetic valves shows a 5-year survival of 68%. While durable, tissue prostheses can calcify, necessitating repair when possible, especially in infants.

    Area of Science:

    • Pediatric Cardiac Surgery
    • Cardiovascular Research
    • Prosthetic Valve Development

    Background:

    • Tricuspid valve disease in children presents complex challenges.
    • Prosthetic valve replacement is a critical intervention for severe tricuspid valve pathology.
    • Understanding long-term outcomes in pediatric patients is essential.

    Purpose of the Study:

    • To evaluate the outcomes of tricuspid valve replacement in pediatric patients.
    • To assess the survival rates and long-term durability of prosthetic tricuspid valves in children.
    • To compare outcomes based on patient age and underlying valve morphology.

    Main Methods:

    • Retrospective review of 11 pediatric patients undergoing 13 tricuspid valve replacements between 1974 and 1986.
    • Analysis of patient demographics, valve morphology, operative details, early and late mortality, and reoperation rates.
    • Comparison with literature data for estimated 5-year survival rates.

    Main Results:

    • Four early deaths occurred, primarily in neonates and infants.
    • Two late deaths and two reoperations for calcified tissue prostheses were observed at 6.5 and 9 years post-implantation.
    • Estimated 5-year survival from literature review is 68% +/- 9% for pediatric patients with prosthetic tricuspid valves.

    Conclusions:

    • Tricuspid valve repair should be prioritized, particularly in infants.
    • Prosthetic valve replacement in older children offers reasonable operative risk and late results.
    • While more durable in the tricuspid position, tissue prostheses are susceptible to late calcification and dysfunction.
