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

这个声音可以在主动脉瓣和肺动脉瓣听诊区被清晰地听到。

The aortic valve can sometimes get inflamed and damaged, leading to aortic regurgitation.

有时主动脉瓣也会被炎症侵及并被破坏，导致主动脉瓣关闭不全。

Recent studies show that most aortic valve surgeries are done by a catheter than more dangerous open-heart surgery.

最近有多项研究表明，大多数主动脉瓣手术是通过导管完成的，而非危险性更高的开胸手术。

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，左边的主动脉瓣以及右边的肺动脉瓣安静地打开。

I think I know a thing or two about aortic valve replacements.

我想我对主动脉瓣置换术略知一二。

Aortic valve stenosis, when the aortic valve does not open properly and blood is forced through a narrow opening.

主动脉瓣狭窄，当主动脉瓣不恰当打开时，血液勉强通过狭窄的开口。

An example of diastolic murmurs is aortic valve regurgitation.

舒张期杂音的一个例子是主动脉瓣反流。

The aorta dilates over time, which is a risk for aortic valve insufficiency, where blood leaks back into the left ventricle during diastole.

主动脉逐渐扩张，这是主动脉瓣关闭不全的危险因素之一；这种情况下，舒张期时血将反流至左心室。

He lifted massively heavyweights, and it turned his aortic valve, the one that looks like a Mercedes sign, into a bicuspid double triangular flap.

他能举起巨大的重物，使用类固醇把他的主动脉瓣，那个看起来像梅赛德斯标志的瓣膜，变成了只有一个二尖瓣膜，两个三尖瓣膜。

So during inspiration, the closing of the pulmonary valve is heard slightly later than the aortic valve, and that's called the physiologic splitting of the S2.

所以在吸气时，肺动脉的关闭声，略晚于主动脉的关闭声，这被称作S2的生理性分裂。
