摘　　要：Introduction: Mechanical valve replacement in pediatric age is a dreaded but sometimes inevitable surgery. The purpose of this study was to determine the mortality of children with mechanical valve prostheses in the short, medium and long term. Patients and Methods: This was a retrospective and descriptive study conducted at the CUOMO cardio-pediatric center at Teaching National Hospital of Fann between January 1^st, 2017 and December 31^st, 2021. We included, children whose age is less than or equal to 16 years of age and who have benefited from a mechanical valve replacement and with a follow-up period of more than 6 months post-operative in the CUOMO cardio-pediatric center. Patients whose age at the time of surgery was over 16 years were excluded;patients who have benefited from bioprosthesis or valvular plastic surgery alone;as well as patients for whom a follow-up of more than 6 months was not found. Statistical analyses were carried out using the SPSS (Statistical Package for Social Science) software version 18 to calculate averages and percentages. Results: We included 85 patients. The average age was 12.84 ± 2.52 years. The male gender predominated with a sex ratio of 1.65. Dyspnea was found in 96.47% of children. Pure mitral regurgitation was the most common valve disease found in 67.06%. Rheumatic etiology was noted in 87.06% of cases. Mono valve replacement was performed in 84.71% of patients and double valve replacement in 15.3% of cases. Major mechanical complications were reported in 8 patients including 5 severe aortic mismatch cases. Hemorrhagic complications were observed in 4 patients requiring surgery. Hemodynamic complications were dominated by right ventricle dysfunction in 14 patients. Supraventricular rhythm disorders were present in 11 patients and one case of ventricular tachycardia. We found six cases of infectious endocarditis. Eight deaths were recorded with a mortality rate of 5.88%. Significant predictors of mortality were stage IV dyspnea of NYHA and preoperatiIntroduction: Mechanical valve replacement in pediatric age is a dreaded but sometimes inevitable surgery.
