Abstract

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 car-dio-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%
