Reemplazo valvular en la edad pediátrica: resultados a corto y largo plazo

Abstract

Introduction and objectivesIn paediatric patients with heart valve abnormalities plasty is always preferred; however, there are cases in which valve replacement is the only option. The objective of this study is to assess the short- and long-term results of paediatric patients who required valve replacement. Material and methodsWith prior informed consent signed by the patient's parents or legal guardian, the data of patients under 18 years of age who underwent valve replacement were entered from the period between 2012 and 2020. ResultsThirteen patients were admitted of whom 84.6% were male, the mean age was 9 years, the mean weight was 29kg, the most affected valve was the mitral valve in 61.5%, followed by the aortic valve at 23.1%. In 61.5% presentation was a double valve lesion. In terms of the aetiology; the most frequent aetiology was congenital in 84.6%; the most widely used prosthesis was St. Jude Medical® number 23. The mean time for extracorporeal surgery was 115min and the mean time for aortic clamping was 75min. Follow-up was 23 months. Conclusionsvalve replacement in the paediatric stage is always a procedure that we should attempt to postpone as long as possible, as it carries a high risk both in surgery and in complications, however this is often not feasible. Although our sample is not in children under 5 years of age, the results are good.
