Objective. To evaluate the effectiveness of percutaneous balloon valvuloplasty (PBV) in pulmonary valvular stenosis (PS) in pediatrics and its results during follow-up. Methods. Eighty patients with PE who underwent PBV between January 2014 and December 2019 were studied. Demographic, echocardiographic and hemodynamic characteristics of the procedure are detailed through descriptive statistics while parametric and non-parametric statistical tests were used in the follow-up in relation to pulmonary insufficiency and restenosis. Results. The age range was 2 years (interquartile range RIQ 10.5 - 72 months), the predominant sex was male with 56.2%. The transvalvular pulmonary gradient decreased from 61.7 ± 21.2 mmHg to 17 mmHg (RIQ: 11 - 26 mmHg). The immediate BPV success rate was 90%. The median follow-up time was 21 months (RIQ: 5-47.5 months). All patients at follow-up showed some degre...

Objetivo. Evaluar la efectividad de la valvuloplastia percutánea con balón (VPB) en estenosis valvular pulmonar (EP) en pediatría y sus resultados durante el seguimiento. Métodos. Se estudiaron 80 pacientes con EP a quienes se les realizaron VPB entre enero de 2014 y diciembre de 2019. Las características demográficas, ecocardiográficas y hemodinámicas del procedimiento se detallan a través de una estadística descriptiva en tanto que en el seguimiento se utilizó pruebas estadísticas paramétricas y no paramétricas con relación a insuficiencia pulmonar y reestenosis. Resultados. El rango de edad fue de 2 años (rango intercuartil [RIQ] 10,5-72 meses), el sexo predominante fue masculino con 56,2%. La gradiente transvalvular pulmonar disminuyó de 61,7 ± 21,2 mmHg a 17 mmHg (RIQ: 11-26 mmHg). La tasa de éxito inmediato de la VPB se situó en el 90%. La mediana del tiempo de ...
