THE RELATIONSHIP BETWEEN LEFT TO RIGHT SHUNTING CONGENITAL HEART DISEASE AND CARDIOTROPHIN-1 IN CHILDREN

Objective: In our study, it was aimed to investigate the interaction of serum cardiotrophin-1 (CT-1) levels in left to right shunting congenital heart disease in children and to evaluate the change of this biomarker with intracardiac defect features.Material and Method: We investigated 45 patients and 23 healthy children between 1 months and 13 years of age in our study. In the patient group, we identified an atrial septal defect (ASD) in 19 cases, a ventricular septal defect (VSD) in 17 cases, an ASD and VSD (ASD+VSD) in 6 cases and a patent ductus arteriosus (PDA) in 3 cases. All children underwent a classical echocardiography (two-dimensional, M-Mode, two-dimensional Doppler and colour Doppler echocardiography). In all patients, plasma BNP levels were measured by chemiluminescence and CT-1 levels were estimated by enzyme-linked immunosorbent assay (ELISA) method, synchronously with echocardiographic studies. Results: A positive correlation was detected between CT-1 and the number of shunts (p<0.02, r=0.35) in patient group and between CT-1 and the defect diameter (p<0.05, r=0.49) in ASD group. Furthermore, the level of CT-1 was higher in cases with a wide VSD than in control group (p<0,05). There was a negative correlation between CT-1 and EF and SF in the group with a higher number of shunts (pulmonary blood flow / systemic blood flow: Qp / Qs> 2) (p<0.001, r=0.71). Conclusion: CT-1 has been found to increase in the group with left to right shunting heart disease. Furthermore, it was indicated that the increase in CT-1 was related to the number of shunts in the group having more intracardiac shunts and a higher risk of failure
