ABSTRACT
OBJETIVO: Avaliar o impacto das cardiopatias congênitas em crianças no crescimento de crianças com síndrome de Down (SD) e a sua recuperação pôndero-estatural após correção cirúrgica. MÉTODOS: Estudo retrospectivo de portadores da SD, entre 1984 e 2007. Excluídos os mosaicos e/ou portadores de morbidades associadas (n=165). Calcularam-se os escores Z para peso (Zpn) e comprimento (Zen) no momento do nascimento. Nos pacientes submetidos à correção cirúrgica (n=60), os escores Zp e Ze foram calculados antes da intervenção cirúrgica e em períodos posteriores, em até cinco anos de pós-operatório (PO). Em relação à população geral, Zp e Ze < 2,5 foram significativos para déficit de crescimento. Utilizado teste do Qui-Quadrado para verificar relação entre peso/estatura e idade no momento da cirurgia e teste T de Student para avaliar o momento em que ocorreu a recuperação PO (P < 0,05). RESULTADOS: As médias de Zpn (n=162) e Zen (n=156) foram -0,95 ± 1,27 e -1,348 ± 1,02. Da amostra total (n=165), 65,5% (n=108) dos pacientes apresentavam doença cardíaca. Dentre os pacientes submetidos (n=60) à cirurgia cardíaca, Zp era inferior a -2,5 em 55% (n=33) e Ze, em 60% (n=36). Com seis meses de PO, 67,4% alcançaram Zp > 2,5. Em um ano, 85,7% atingiram Ze > 2,5. Dividindo este grupo por idade, na época da cirurgia, em tercis não ocorreu diferença. CONCLUSÕES: Observou-se déficit pôndero-estatural em relação à população geral desde o nascimento, sendo maior nas crianças com cardiopatia de indicação cirúrgica. A recuperação PO ocorreu em seis meses para o peso e em um ano para a estatura, sem diferença quanto à idade no momento cirúrgico.
OBJECTIVE: To evaluate the impact of congenital heart diseases in growth of children with Down syndrome (DS) and the weight-height recovery after surgical correction. METHODS: Retrospective study of the DS patients between 1984 and 2007. Excluding the mosaics and/or patients with associated morbidities (n=165). Calculated Z scores for weight (Zwb) and length (Zlb) at birth. Those patients submitted to surgical correction (n= 60) these scores (Zw/Zh) were evaluated before surgery and in subsequent periods to five years. Malnutrition was defined as weight/height Z-score < 2.5. Used Chi-square test to verify the relation between weight/length and age at the time of surgery and Student T test to evaluate the postoperative (PO) time of recovery (P < 0.05). RESULTS: Means Zwb (n = 162) and Zlb (n = 156) were -0.95 ± 1.27 and -1.348 ± 1.02. From the total data (n = 165), 65.5% (n = 108) presented heart disease. Those submitted to cardiac surgery (n = 60), Zw was below -2.5 in 55% (n = 33) and Zh in 60% (n = 36). After six months PO, 67.4% achieved Zw > 2.5. In one year, 85.7% achieved Zh > 2.5. Dividing this group by age in tertiles at time of surgery no difference was found. CONCLUSIONS: We concluded that malnutrition common in children with DS since birth. DS children with congenital heart and surgical indication were smaller and lighter than those without or with mild disease. PO recovery occurred in 6 months for weight and one year for height, with no difference in the age at the time of surgery.

Se realizó estudio retrospectivo de pacientes con síndrome de Down que fueron intervenidos quirúrgicamente para corrección o paliación de su cardiopatía congénita de enero de 1996 a diciembre del 2000 en el Instituto Nacional de Cardiología "Ignacio Chávez". Las variables analizadas fueron: edad al momento quirúrgico, sexo, tipo de cardiopatía, presión pulmonar y cirugía practicada, tiempo de estancia en la unidad de terapia intensiva, complicaciones y mortalidad. En el periodo analizado fueron intervenidos quirúrgicamente 37 pacientes. La media de edad fue de 2 años con 8 meses con un rango de 2 meses a 17 años. La comunicación interventricular fue la cardiopatía más frecuente (35%) y estuvo asociada a persistencia del conducto arterioso en el 61% de los casos. Seis pacientes (16%) tenían defecto de la tabicación atrioventricular, la mitad tipo A y la otra mitad tipo C de Rastelli. Doce pacientes (32%) tenían como única lesión la persistencia del conducto arterioso. Tres pacientes tuvieron tetralogía de Fallot y dos comunicación interatrial. 34 de los pacientes (90%) tenían hipertensión arterial pulmonar siendo leve en 6, moderada en 5 y severa en 23 (62%). El tipo de cirugía fue correctivo en el 89% de los pacientes y el tiempo de estancia promedio en terapia intensiva fue de 2.5 días. Las complicaciones más frecuentes fueron los trastornos del ritmo y/o de conducción en 8 pacientes (22%), tres correspondieron a bloqueo AV completo, y la mortalidad fue del 8%. En el niño con síndrome de Down es importante una evaluación clínica completa con miras a establecer un tratamiento quirúrgico oportuno.
We made a retrospective study of patients with Down's syndrome that were surgically treated for correction or paliation for their congenital heart disease between january 1996 to december of the 2000 in the National Institute of Cardiology "Ignacio Chávez". We analyzed these variables: age at the surgical moment, sex, congenital heart defect, pulmonary arterial pressure, type of surgery, time of stay in the intensive care unit, complications and mortality. In this period they were surgically treated 37 patients. The mean age was of 2 years with 8 months with a range of 2 months to 17 years. The interventricular defect was the most frequent one (35%) and it was associated to persistent ductus arteriosus in the 61% of the cases. Six patients(16%) had atrioventricular septal defect, the half of them type A and other half type C of Rastelli classification. Twelve patients (32%) had one lesion persistent ductus arteriosus. Three patients had tetralogy of Fallot and two atrial septal defect. Pulmonary hypertension was found in 90% of the patients, in 23 was severe (62%), moderate in 5 and slight in 6 (16%). The surgical treatment was corrective in 89% patients and the average time of stay in intensive care unit was of 2.5 days. The most frequent complication was rhythm and conduction disorders, in 8 patients (22%), three with complete AV block and the mortality was of 8%. In the patients with Down´s syndrome is important a complete clinical evaluation with an eye toward establishing an opportune surgical treatment. (Arch Cardiol Mex 2004; 74:39-44).

Se realiza un estudio retrospectivo de 70 lactantes operados de comunicacion interventricular, en el Cardiocentro del Hospital Pediatrico Docente "William Soler", durante el periodo de 1989 a 1992. Todos los pacientes estaban desnutridos, el 60 por ciento padecia de insuficiencia cardiaca congestiva, el 14 por ciento hipertensos pulmonares y el 11,4 por ciento con sindrome de Down. El 10 por ciento presento bajo gasto cardiaco a la salida de la circulacion extracorporea y la mortalidad posoperatoria fue de 9 pacientes, para el 12,8 por ciento
