Background and Aim: Congenital hypothyroidism results from abnormal structure, position, or hormone production of the thyroid gland. Since common genetic and developmental pathways exist, congenital heart disease may accompany it.
Methods: In this cross- sectional descriptive study, 75 children with congenital hypothyroidism were evaluated by echocardiography using the census method. They had been detected during the national screening program of neonates; the diagnosis had been documented then. Patients with Down syndrome, low birth weight, and less than 1-month age were excluded from the study. Mean and standard deviations for quantitative variants and frequency for qualitative variants were applied.  Student’s test- test, Pearson’s chi- square, and correlation index were used for data analysis.
Results: Congenital heart disease was detected in 20% of these hypothyroid children, including 12% atrial septal defect, 4% atrial and ventricular septal defects, and 4% mitral valve prolapse. Patent foramen ovale was detected in 21 children. No cardiac abnormality was reported in 52% of children. Gestational age and birth weight were significantly lower in the congenital heart disease group (P=0.000).
Conclusion: Congenital heart disease is relatively prevalent in Iranian children with congenital hypothyroidism. We recommended cardiac evaluation for all hypothyroidism cases detected by the national screening program
