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.
卵圓孔未閉會導致心臟上部腔體，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.
這個連接可能導致輸送養(yǎng)分和氧氣的血液，在流經(jīng)全身其他部位以后，本應進入肺部獲取更多氧氣時，突然轉向進入左心房。
This may be due to significant inflammation due to extensive lesion sets in the left atrium.
導致這樣的結果可能是由于炎癥，大面積損傷嵌入到了左心房。
