MethodsA cross-sectional study based on echocardiographic records of the largest pediatric cardiology center in Angola included all children and adolescents (0 to 18 years old) with VSD between April 2010 and March 2011. The diagnosis was made by transthoracic and Doppler echocardiography with a Medison SA 8000 system. The sample was divided into two groups: Group 1, isolated VSD; and Group 2, VSD associated with other congenital heart defects (CHDs). Age, gender, type of VSD, associated CHDs and genetic syndromes were assessed. ResultsA total of 490 CHDs were diagnosed, of which 283 were VSDs. In Group 1 (140, 49%) the mean age was 29±36 months. The most frequent age (mode) at diagnosis was 24 months. There was no predominance of gender (ratio 1:1). The majority (127, 91%) had perimembranous VSD. In Group 2 (143, 51%) 113 patients (79%) had one, 27 patients (19%) had two and three patients (2%) had three other CHDs. Trisomy 21 was the most common genetic syndrome (23, 96%). ConclusionsThe study shows that VSD is the most common CHD in childhood, the diagnosis is made late and almost half of VSDs are associated with other CHDs. ER -
