ABSTRACT
Objective: To aim the incidence of congenital and acquired heart disease in our institution. Material and methods: A retrospective, transverse, descriptive and comparative study was conducted, from August 2001 to July 2011, in which we evaluated echocardiograms of patients between the ages of newborn to 18 years of age. They were grouped by heart disease. In the last statistical analysis, we obtained the frequency of occurrence and the proportional value of each cardiopathy. Results: In the last 10 years, we founded 4,544 patients with heart disease. The 14 most common cardiopathies represented 89% of the statistic. The congenital heart disease most frequent was persistent ductus arteriosus with 896 patients (19%), and the acquired heart disease most frequent was myocarditis with 116 patients (2.5%). The tetralogy of Fallot was most frequent congenital heart disease with cyanosis. Conclusions: The frequencies of congenital and acquired heart disease are different in difference geographic and ethnics areas.
Objetivo: Mostrar la frecuencia de las cardiopatías congénitas y adquiridas en nuestra institución. Material y métodos: Se realizó un estudio retrospectivo, transversal y descriptivo donde se revisaron las libretas de los estudios ecocardiográficos, realizados en pacientes cuyas edades fueron de recién nacidos a 18 años y se agruparon por tipos de cardiopatías. En el análisis estadístico obtuvimos la frecuencia de ocurrencia, el valor de la proporción de cada cardiopatía. Resultados: En los últimos 10 años ingresaron 4,544 pacientes con cardiopatía. Las 14 cardiopatías más frecuentes correspondieron al 89.21% de la estadística. La cardiopatía más frecuente fue la persistencia del conducto arterioso con 896 pacientes (19%) y la cardiopatía adquirida más frecuente fue la miocardiopatía, con 116 pacientes (2.5%). La tetralogía de Fallot fue la cardiopatía cianógena más frecuente, con 139 pacientes (3%), a diferencia de otros países. Conclusiones: La frecuencia de cardiopatías congénitas y adquiridas es variable en diferentes áreas étnicas y geográficas.

INTRODUCTION AND OBJECTIVES: A longitudinal, retrospective, observational descriptive study was done at the National Institute of Pediatrics in Mexico City to determine the incidence, type of heart disease and clinical course in patients with Down syndrome (DS), and to compare the findings with data from other countries. Down syndrome is a disease caused by trisomy of chromosome 21. The frequency of presentation in one in 650 live births. Frequency in the general population is about 1%. Cardiac malformation is the main cause of mortality in the first 2 years of life. PATIENTS AND METHOD: In a 5-year period 275 patients (aged neonate to 13 years) were diagnosed with DS. Diagnosis was based on echocardiogram, catheterization, genetics, surgical exploration or necropsy. Age, sex, clinical manifestations, mother's age, type of heart defect were recorded. RESULTS: Of the 275 children with DS, 160 had congenital heart disease. The most frequent cardiopathies were interauricular septal defect (IASD), interventricular septal defect (IVSD) and patent ductus arteriousus (PDA) (90%). In contrast to the data from other countries, only 14 patients (8%) had atrioventricular septal defect (AVSD). Twenty-five patients died (15%) from sepsis and cardiogenic shock. CONCLUSIONS: At our institute 58% of the children with DS had congenital heart malformation. The most frequent cardiopathies were different from those reported in other countries.
