Improved ascertainment of cardiovascular malformations in infants with Down's syndrome, Atlanta, 1968 through 1989 : implications for the interpretation of increasing rates of cardiovascular malformations in surveillance systems.
Several birth defects surveillance systems have shown an upward trend in the birth prevalence of several congenital cardiovascular malformations.
Improvements in clinical ascertainment have been suggested as an explanation for this increase.
For several decades, 40-50% of infants with Down's syndrome have been reported to have cardiac defects associated with the unbalanced genotype.
Therefore, secular changes in the frequency of ascertained cardiovascular malformations among infants with Down's syndrome in surveillance systems could shed light on improvements in the ascertainment of these defects.
