Aim: There is a limited number of studies on the role of galectin-3 as a cardiac biomarker in the pediatric population. We aimed to investigate galectin-3 level and its relationship with N-terminal prohormone of brain natriuretic peptide (NT-proBNP) in children with secundum atrial septal defect (ASD). Material and Methods: Twenty-seven patients with secundum ASD formed the patient group. Thirty healthy children of similar age and gender formed the control group. The largest ASD diameter measured from any window with transthoracic echocardiography was recorded as the ASD size. Blood samples were collected for NT-ProBNP and galectin-3. Results: Children with secundum ASD had significantly higher NT-ProBNP levels compared with the healthy children (p=0.003). Galectin-3 levels of children with secundum ASD were similar to those of the healthy children (p=0.377). There was a statistically positive correlation between galectin-3 and NT-ProBNP levels in children with secundum ASD (rho=0.454, p=0.017). The area under the curve of galectin-3 was not statistically significant (AUC=0.537; p=0.643). Conclusion: Although there was an increase in NT-ProBNP level in patients with secundum ASD, galectin-3 level did not change. Although NT-ProBNP was a valuable biomarker for the prediction of secundum ASD, galectin-3 had no role in predicting this disease.
