Mitral and aortic valve replacement in children: Last decade results with latest generation prothesis Introduction: Mitral (MVR) and aortic (AVR) valve replacement are uncommon interventions in pediatric patients and the published series report high morbidity and mortality. Objective: Evaluate mid-term results in children with MVR and AVR during the last 10 years, in order to establish morbidity, mortality and life-quality. Methods: Retrospective analysis of 26 children with median age 5,6 years-old, who underwent MVR (17 cases) and AVR (11 cases) between March 1992 and June 2003. Results: 26 surgeries were performed, implanting 28 prothesis (26 mechanical and 2 biological). 3 patients (12%) died during the first month. The median follow-up period was 6,2 years, with 87% survival. Three patients required new surgery because of non-structural deterioration of the prosthetic valve. All survivors have a normal level of activity according to their age, with restriction only on contact sports. Conclusions: Valve replacement in children with severe valvular disease has satisfactory mid-term results
