    Area of Science:

    • Cardiology
    • Pediatric Surgery
    • Biomedical Engineering

    Background:

    • Infantile heart failure and pulmonary hypertension pose significant clinical challenges.
    • Prosthetic valve implantation is a critical intervention for severe valvular heart disease in infants.
    • The Björk-Shiley prosthetic valve is a mechanical device used for valve replacement.

    Observation:

    • A 7-month-old infant weighing 4.5 kg presented with rapidly progressive pulmonary arteriolar hypertension and heart failure.
    • The infant underwent successful mitral annulus insertion of a 1.7 cm Björk-Shiley prosthetic valve.
    • Postoperative complications were managed, and the patient exhibited rapid clinical improvement.

    Findings:

    • Successful mitral valve replacement using a Björk-Shiley prosthesis in a critically ill infant.
    • Effective management of severe pulmonary arteriolar hypertension and heart failure post-surgery.
    • Demonstration of significant postoperative recovery and improved cardiac function.

    Implications:

    • Mitral valve replacement is a viable therapeutic option for carefully selected infants with severe heart failure.
    • Early surgical intervention can lead to substantial clinical improvement and better outcomes in pediatric cardiac patients.
    • Advances in prosthetic valve technology and surgical techniques enhance treatment possibilities for complex congenital heart disease.
