请问楼上你怎么知道亚洲孩子会比较常见?有什么这方面资料可以共享看看?我在网上没找到相关信息。
谢谢!
这个小白点可能是钙的deposit,不影响心脏功能,一般第三个trimester就会消失。只是这个是down syndrome的一个soft marker。1/3亚洲人baby有这个现象,在后期会自己消失。
你可以GOOGLE ‘EIF'
Echogenic intracardiac focus (EIF) is a small bright spot seen in the baby’s heart on an ultrasound exam. This is thought to represent mineralization, or small deposits of calcium, in the muscle of the heart. EIFs are found in about 3-5% of normal pregnancies and cause no health problems.
EIFs themselves have no impact on health or heart function. Often the EIF is gone by the third trimester. If there are no problems or chromosome abnormalities, EIFs are considered normal changes, or variants. |
