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。

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。

For example, if we were learning about aortic regurgitation, I would understand, okay, aortic regurgitation might present with these symptoms, but I didn't understand what aortic regurgitation is.

例如，如果我们正在学习主动脉瓣反流，我会理解，好吧，主动脉瓣关闭不全可能会出现这些症状， 但我不明白主动脉瓣关闭不全是什么。

You should know that before you start learning about aortic regurgitation, or different heart sounds, or kind of weird syndromes that the heart might get.

在你开始了解主动脉瓣反流、不同的心音或心脏可能出现的奇怪综合症之前，你应该知道这一点。
