Abstract
Introducción y objetivos: El canal auriculoventricular completo supone el 3% de las cardiopatías congénitas. Su pronóstico depende del estado de la válvula auriculoventricular izquierda post-reparación. Analizaremos nuestros resultados de morbimortalidad y necesidad de reintervención. Métodos: Estudio observacional retrospectivo, incluyendo a los pacientes con canal auriculoventricular completo intervenidos en nuestro centro entre enero de 2008 y julio de 2021. Resultados: Fueron intervenidos 57 pacientes. La mediana de edad y de peso fueron 6 meses y 5,8 kg, respectivamente (rango intercuartil 4-7 meses y 4,8-6,7 kg). La mortalidad hospitalaria fue de 3 pacientes (5,3%). El 7,2% de los pacientes necesitaron reintervención precoz sobre la válvula auriculoventricular izquierda. La supervivencia global fue del 88,6% (seguimiento mediano de 4,7 a˜ nos [rango intercuartílico: 1,5-10,9]; seguimiento completo en el 93% de los pacientes). La libertad de reintervención sobre la válvula auriculoventricular izquierda fue del 83,7%. La válvula auriculoventricular izquierda presentaba regurgitación menor de III/IV en el 90,2% de los pacientes al final del seguimiento. La intervención antes de 3 meses (p = 0,001), la hipertensión pulmonar preoperatoria (p = 0,007) y la estenosis valvular auriculoventricular izquierda postoperatoria (p = 0,001) fueron factores de riesgo de mortalidad. El peso inferior a 4 kg (p < 0,0001), la edad menor de 3 meses (p < 0,0001), la no actuación sobre el cleft (p = 0,033) y la estenosis valvular postopetoria (p < 0,0001) fueron factores predisponentes de reintervención valvular. Conclusiones: La corrección del canal auriculoventricular entre los 3 y 6 meses presenta buenos resultados de morbimortalidad. El cierre del cleft previene la necesidad de reintervención sobre la válvula auriculoventricular izquierda.
Introduction and objectives: Complete atrio-ventricular septal defect accounts for 3% of congenital heart disease. Its prognosis depends on the status of the left atrio-ventricular valve after repair. We will analyse our results in terms of morbidity and mortality, and need for reoperation. Methods: Retrospective observational study, including patients who underwent a complete surgical correction of atrio-ventricular septal defect in our centre between January 2008 and July 2021. Results: 57 patients were treated. Median age and weight were 6 months and 5.8 kg respectively (inter quartile range 4-7 months and 4.8-6.7 kg). Inhospital mortality was 3 patients (5.3%). Of the patients, 7.2% required early reoperation to the left atrio-ventricular valve. Overall survival was 88.6% (median follow-up of 4.7 years; interquartile range: 1.5-10.9; complete follow-up in 93% of patients). Freedom from reoperation to the left atrioventricular valve was 83.7%. The left atrioventricular valve showed regurgitation lower than III / IV in 90.2% of the patients at the end of follow-up. Surgery before 3 months (p = .001), preoperative pulmonary hypertension (p = .007), and postoperative left atrio-ventricular valve stenosis (p = .001) were risk factors for mortality. Weight less than 4 kg (p< .0001), age less than 3 months (p < .0001), no closure of the cleft (p = .033), and postoperative valve stenosis (p < .0001) were risk factors for valve reoperation. Conclusions: Surgical correction of atrioventricular septal defect between 3 and 6 months shows good morbidity and mortality results. Closure of the cleft prevents the need for reoperation to the left atrioventricular valve.
