High Prevalence of Interatrial Communications During the First Three Months of Life

Abstract:

The objective of this study was to analyze retrospectively the results of color Doppler echocardiographic (CDE) investigations performed for the first time on a child under circumstances where there was unrestricted access to CDE. The records were obtained from a tertiary referral center at a university hospital serving a population of about one million. The patients were children (n= 284) ages 0 days to 15 years 9 months referred for CDE over a 1-year period. Heart abnormalities were found in 119 children (42%). Among the children <3 months old, a heart abnormality was detected by CDE in 71%. The most prevalent diagnosis was atrial septal defect, particularly during the first 3 months of life, where the intraatrial communications accounted for 78% of the heart abnormalities. It is concluded that there is high prevalence of atrial communications during the first 3 months of life. The spectrum of diagnoses among newborns differs from the previously reported frequencies of congenital heart diseases. Better equipment (CDE) seems to diagnose abnormalities that might not be diagnosed otherwise.
