Successful use of MITRIS RESILIA mitral valve in pediatric patients

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.
