摘要

使用彩色杜卜勒超音波儀，針對130名出生一周內之新生兒施行心臟掃瞄，結果發現9位新生兒（約7%）有多發性心房中隔間隙與分流。其中8位有2個間隙，另1位有4個間隙。
間隙位於卵圓孔上綠與卵圓孔瓣膜頂端之間者，分類為間隙A（乃俗稱之卵圓孔活門）：間隙位於卵圓孔瓣膜者分類為間隙B（瓣膜穿孔）。9位新生兒均有一個間隙A；其中8位各有l個間隙B。9位新生兒當中有6位（共6個間隙A，8個間隙B）規律地在年齡l、3、6個月時接受心超音波追蹤檢查。6個月大時，4個間隙A及7個間隙B自動癒合。
結論：百分之七的中國嬰兒有多發性心房中隔間隙及分流。不論間隙的位置在A或B均有自動癒合的傾向。

In a prospective study on the integrity of the interatrial septum in the neonates, multiple interatrial septal defects or openings with shunting were discovered in nine neonates by means of the color flow mapping technique used in their first week of life among 130 Chinese neonates. Eight of the nine neonates had two openings each, and the remaining one had four openings. Thus a total of 20 openings were found in the 9 neonates. Openings located between the tip of the flap valve and the superior limbus of the foramen ovale were classified as ”location A openings” (valve-like openings). Those located at the flap valve itself were classified as ”location B openings” (fenestrations). Each of the 9 neonates had one opening at location A, eight of them had another opening at location B, one had three openings at location B. Six of the nine neonates were followed up at age of one month, three months and six months by means of color-flow mapping, with a total of six openings at location A and eight openings at location B. Four out of the six openings of location A and seven out of the eight openings at location B closed spontaneously before the age of six months. In conclusion, seven percents (9/130) of these Chinese neonates have multiple interatrial openings. The openings tend to close spontaneously, regardless of their locations.
