Abstract
Here, we demonstrate the capability of implanting the MITRIS RESILIA mitral valve in pediatric patients with severe mitral valve disease requiring mitral valve replacement. The MITRIS RESILIA valve is a bioprosthetic valve with a unique design allowing for improved physiological flow dynamics (minimizing left ventricular outflow obstruction) and potential for future valve-in-valve intervention. We retrospectively analyzed two cases: a 9-year-old with rheumatic heart disease and a 12-year-old with juvenile idiopathic arthritis-related mitral valve deterioration. Both patients underwent successful mitral valve replacement with the MITRIS RESILIA valve, demonstrating significant postoperative improvement in valve function and symptom relief. Follow-up echocardiograms 1 year later showed stable valve function with no significant regurgitation or stenosis, indicating satisfactory short-term outcomes. © 2024
