left atrium

基本解釋

A P.F.O. is a tunnel that connects the upper chambers of the heart — the right atrium and the left atrium.
卵圓孔未閉會(huì)導(dǎo)致心臟上部腔體，即左心房和右心房之間存在一條通道連接。
The opening allows blood that has given up nutrients and oxygen after traveling through the rest of the body to shunt into the left atrium, instead of going into the lungs to pick up more oxygen.
這個(gè)連接可能導(dǎo)致輸送養(yǎng)分和氧氣的血液，在流經(jīng)全身其他部位以后，本應(yīng)進(jìn)入肺部獲取更多氧氣時(shí)，突然轉(zhuǎn)向進(jìn)入左心房。
This may be due to significant inflammation due to extensive lesion sets in the left atrium.
導(dǎo)致這樣的結(jié)果可能是由于炎癥，大面積損傷嵌入到了左心房。
