THE PREVALENCE OF CONGENITAL HEART DISEASES AMONG ROMANIAN CHILDREN — EXPERIENCE OF A SINGLE CENTER

Abstract

Aim. Congenital heart defects (CHD) are the leading cause of infant mortality becoming an important public health problem. Time trends in CHD by specific phenotype and with long follow-up time are rarely available for a large pediatric population.Material and methods. We present the prevalence of CHD over the past 5 years among Romanian children. Individuals with CHDs were classified by several criteria including type of pathology, association of the pathology with various syndromes and abnormalities, postnatal complications or treatment.Results. The overall CHD birth prevalence increased. Generally, prevalence increased for defects diagnosed in infancy and preschoolers patients. Isolated septal defects such as atrial septal defect (ASD) was present in 29,69% of patients while transposition of the great vessels was present in 1,87% of children, respectively. Among the severe defects, tetralogy of Fallot — atresia/hypoplasia of the pulmonary artery association showed the largest prevalence. Considering the syndromatic CHD, the highest incidence (78,78%) was recorded for Down syndrome, followed by Turner syndrome. The most frequent postnatal complication in CHD patients was cardiomegaly, followed by pulmonary hypertension. Only 29,94% of the patients underwent corrective surgery, the rest remained on medication. The highest incidence rate was recorded for tetralogy of Fallot (42,85%), followed by isolated septal defects. On average, tetralogy of Fallot cases were operated on 16,6 months after diagnosis while transposition of the great vessels after 2,5 months.Conclusion. The increasing prevalence of CHDs reported was confirmed in the present study. This is mostly due to an increasing number of isolated septal defects diagnosed in infancy. In the future, the etiology of CHD needs to be further clarified and prospective birth defect registries covering the a large population are needed to determine the exact birth prevalence of CHD.
