So how on earth did you get access to this drug?

来开发肺动脉高压的医治方法。

But not everyone who has this disease has been so fortunate.

寻找肺动脉高压的治愈方式。

Is it the P.A.? I'm not seeing it.

是肺动脉吗 我看到啊。

And that's up in the pulmonary artery. The wire lead acts like permanent paddles on a heart.

在肺动脉上。导线的作用就像心脏上的永久性划片。

Blood flows from the left ventricle into the aorta and from the right ventricle into the pulmonary arteries.

血从左心室流主动脉，以及从右心室流肺动脉。

This is heard loudest in the aortic valve and pulmonary valve area.

这个声音可以在主动脉和肺动脉听诊区被清晰地听到。

But, unlike the tricuspid valve, the pulmonary valve doesn't have any of those chordae tendineae.

但与三尖，肺动脉没有腱索。

On the left side of the heart, the aortic arch should be the highest up followed by the pulmonary artery.

心脏左侧的最高点应为主动脉弓，下面是肺动脉。

Notice though, that this one big artery does split into the aorta and pulmonary artery.

注意，这条大动脉确实会分成主动脉和肺动脉。

The " great arteries" , are these two main arteries taking blood away from the heart —the aorta and pulmonary artery.

大动脉指的就是这两条把血液带离心脏的主要动脉：主动脉和肺动脉。

Remember how fluid buildup increased pressure in the pulmonary artery?

还记得体液积聚如何增加肺动脉压力吧？

Once it's fully developed, the aorta comes from the left ventricle and the pulmonary artery comes from the right ventricle.

一旦心脏完全发育，可见主动脉来自于左心室，肺动脉来自于右心室。

A blood clot wedged into the lungs causing his heart to disfigure.

血栓堵在了肺动脉，导致了心脏变形。

Right atrial enlargement is usually due to pulmonary hypertension.

右心房增大通常由肺动脉高压引起。

And to do that, the aortic valve, on the left side, and the pulmonic valve, on the right side, quietly open up.

为泵出血液，左边的主动脉以及右边的肺动脉安静地打开。

If these two great arteries, the aorta and pulmonary artery, don't divide, you essentially have this massive artery coming from both ventricles.

如果主动脉和肺动脉这两条大动脉分开的话，你就会有这条从心室发出的大动脉。

Pulmonary vessels include the pulmonary artery and its branches, and the veins that drain the lung capillaries.

肺动脉携带来自于右心室的低氧血液，而肺静脉将来自于肺的富氧血液运至左心房。

Since there's more oxygenated blood over here, patients will have an increased oxygen saturation in the right ventricle and pulmonary artery.

既然来了更多含氧高的血液，患者右心室和肺动脉的氧饱和度就升高了。

When the atria contracts, blood in the right atrium is forced through the tricuspid valve into the right ventricle.

当心室收缩时，右室血液经肺动脉进肺动脉，时三尖关闭防止血液回流至心房。

The pulmonary arteries carry deoxygenated blood from the heart to the lungs.

肺动脉将脱氧血从心脏输送到肺。
