BACKGROUND: Down syndrome (DS) is a common chromosomal abnormality associated with congenital heart disease (CHD). These cardiac abnormalities are known to be associated with pulmonary arterial hypertension (PAH).
METHODS: The aim of this study was to assess the prevalence of PAH in DS children with CHD and to compare it with PAH prevalence in non-syndromic children with CHD. It was a cross-sectional study including all children presenting to Cardiology Department at a tertiary care center between Jan 2007 and Dec 2010.
RESULTS: Thirty-five DS children with CHD were compared with 38 non-syndromic children with CHD. Atrioventricular septal defect (AVSD, 13/35) was the commonest CHD among DS children while isolated VSD (26/38) accounted for maximum cases in non-syndromic CHD. PAH was more prevalent among DS children with CHD (18/42) than among the control group (7/38, p = 0.038). In addition, 14/19 patients with AVSD in the entire cohort developed PAH.
CONCLUSION: DS children with CHD have a higher predisposition to develop PAH, and the likelihood is highest with underlying AVSD.
