Elevated MSAFP levels and congenital heart defects: lack of an association.
This study was undertaken to evaluate the relationship between elevated maternal serum alpha fetoprotein (MSAFP) levels and congenital heart defects. Thirty-two infants with isolated major congenital heart defects and whose mothers had had MSAFP screening were identified. In only one case was the MSAFP greater than 2.3 multiples of the median. A review of our experience with women with elevated MSAFP levels did not document a higher rate of congenital heart malformations than would be expected based on estimated frequencies in the general population.
