Resumo

Introducción: La valvuloplastía aórtica con balón (VAB) es el procedimiento de elección para el manejo de La estenosis valvular aórtica en pediatría. La mortalidad y la supervivencia libre de reintervenciones no han sido evaluadas en Colombia. Objetivo: Determinar la sobrevida global y los factores asociados de reintervención valvular aórtica (RVA) en los pacientes tratados con VAB en la Fundación Cardio infantil – Instituto de Cardiología entre febrero del 2005 y marzo del 2013. Métodos: estudio estudio analítico de cohorte Resultados: Se evaluaron 69 VAB. La edad promedio de realización fue de 74,89 meses. La relación hombre: mujer de 4:1. Un 30,5% de los pacientes tenían malformaciones cardiacas asociadas. Se presentaron complicaciones en 13% de las VAB. La presión sistólica del ventrículo izquierdo presento una reducción promedio de un 63,6%. Se siguieron el 81,2% de las VAB, encontrando a los 9 años de seguimiento, supervivencia de 89,2% y necesidad de RVA en 14,2% de las VAB, siendo más frecuentes en VAB con gradiente post-VAB mayor de 35 mmhg (p= 0.005), con un RR de 6.6. Los otros factores no mostraron relaciones estadísticamente significativas (edad, morfología valvular, malformaciones asociadas, insuficiencia aórtica post-VAB). Conclusiones: La VAB es eficaz en el manejo de la EVA congénita, con una mortalidad y supervivencia libre de RVA similares a las encontradas en estudios previamente publicados. El gradiente post VAB mayor de 35 mm hg fue el único factor de riesgo que se correlacionó con la supervivencia libre de RVA.

Introduction: The aortic balloon valvuloplasty (BAV) is the procedure of choice for the management of aortic valve stenosis in children. Mortality and reoperation-free survival have not been evaluated in Colombia. Objective: To determine overall survival and associated factors of aortic valve reoperation (AVR) in pediatric patients treated with BAV in Fundación Cardio infantil – Instituto de Cardiología between February 2005 and March 2013. Methods: analytical study cohort study Results: We evaluated 69 VAB. The average age was 74.89 months. The male: female ratio of 4: 1. 30.5% of patients had associated cardiac malformations. Complications occurred in 13% of the BAV. The left ventricular systolic pressure presented an average reduction of 63.6%. 81.2% of BAV were followed, finding 9 years of follow-up, survival of 89.2% and necessity of RVA in 14.2% of BAV, being more frequent in BAV gradient greater post-BVA 35 mmHg (p = 0.005), with a RR of 6.6. Other factors showed no statistically significant relationships (age, valvular morphology, associated malformations, aortic regurgitation post-VAB). Conclusions: The BAV is effective in the management of congenital EVA, with a mortality and RVA free survival similar to those found in previously published studies. The post BAV gradient greater than 35 mm Hg was the only risk factor that correlated with RVA free survival.
