ABSTRACT
ABSTRACT CONTEXT AND

OBJECTIVE:

Down syndrome is the most common genetic disorder, affecting 1/700 live births. Among the clinical findings, one constant concern is the high prevalence of congenital heart disease. The objective of this study was to determine the prevalence and profile of congenital heart disease among patients attended at a Down syndrome outpatient clinic in southern Brazil between 2005 and 2013. DESIGN AND

SETTING:

Cross-sectional study conducted in a referral center.

METHODS:

Data were retrospectively gathered from the medical files of 1,207 patients with Down syndrome, among whom 604 (50.0%) had been diagnosed with congenital heart disease. These data were subjected to descriptive analysis using the Statistica software.

RESULTS:

Among the 604 patients with congenital heart disease, 338 (55.8%) were male and 269 (44.5%) were female. The most common heart diseases were atrial septal defect in 254 patients (42.1%); total atrioventricular septal defect in 91 (15.1%); atrial septal defect and ventricular septal defect in 88 (14.6%); ventricular septal defect in 77 (12.7%); patent ductus arteriosus in 40 (6.6%); patent foramen ovale in 34 (5.6%) patients; tetralogy of Fallot in 12 (2%); and other diseases in 8 (1.3%). Pulmonary hypertension was present in 57 (9.4%). Out of the total, 150 patients (24.8%) underwent cardiac surgery.

CONCLUSION:

The high prevalence of congenital heart disease among the patients at the Down syndrome outpatient clinic (50%) was similar to findings from other studies and justifies investigation during the neonatal period, so as to decrease mortality and morbidity.
RESUMO
RESUMO CONTEXTO E

OBJETIVO:

A síndrome de Down é a anomalia genética mais comum e afeta 1/700 nascidos vivos. Entre os achados clínicos, uma preocupação constante é a alta prevalência de cardiopatia congênita e o objetivo do presente estudo é determinar a prevalência e o perfil de cardiopatia congênita em pacientes atendidos em um ambulatório de síndrome de Down no período de 2005 a 2013 no sul do Brasil. TIPO DE ESTUDO E LOCAL Estudo transversal conduzido em um centro de referência.

MÉTODOS:

Foi realizada coleta retrospectiva de dados de 1.207 prontuários de pacientes com síndrome de Down, com 604 (50,0%) diagnosticados com cardiopatia congênita. Os dados foram submetidos a análise descritiva, utilizando-se o programa Statistica.

RESULTADOS:

Entre os 604 pacientes com cardiopatia congênita, 338 (55,8%) eram do sexo masculino e 269 (44,5%) do feminino. A cardiopatia mais comum foi comunicação interatrial, observada em 254 (42,1%) pacientes, defeito de septo atrioventricular total, em 91 (15,1%), comunicação interatrial em conjunto com comunicação interventricular, em 88 (14,6%), comunicação interventricular, em 77 (12,7%), persistência do canal arterial, em 40 (6,6%), forame oval patente, em 34 (5,6%), tetralogia de Fallot, em 12 (2%) e outras cardiopatias observadas em oito (1,3%) pacientes. Hipertensão pulmonar esteve presente em 57 (9,4%). Do total, 150 (24,8%) pacientes foram submetidos a cirurgia cardíaca.

CONCLUSÃO:

A elevada prevalência das cardiopatias congênitas nos pacientes do ambulatório da síndrome de Down, de 50%, semelhante à encontrada em outros estudos, justifica a investigação no período neonatal, com diminuição da mortalidade e morbidade.
