Right after the S1 sound, the aortic and pulmonic valve open up allowing blood to get pushed out to the body and this period of time is called systole.

在S1之后，主动脉瓣和肺动脉瓣打开，分别使得血液流入身体各组织以及肺部，这段时期叫做心脏收缩期。

HOCM, VSD, a sclerosis, aortic flow murmur, at least the medical students' final level.

HOCM，VSD，硬化症，主动脉血流杂音，至少这是医学生最后一年水平。

Why, I cried, you have an aortic aneurism!

怎么，你得了动脉血瘤症！

The aortic I may rely upon, but I should value your opinion upon the mitral.

我大动脉还好，可是对于我僧帽瓣，我要听听您宝贵意见。

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。

I scrubbed in on a...an abdominal aortic aneurysm. It's a 12-hour surgery.

我曾参加一个...腹腔大动脉瘤手术。那手术持续12小时。

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

他能举起巨大重物，使用类固醇把他主动脉瓣，那个看起来像梅赛德瓣膜，变成了只有一个二尖瓣膜，两个三尖瓣膜。

Now, the " DUB" sound — and, just to be clear, I am not talking about dubstep sounds — that's the aortic and pulmonary semilunar valves closing at the start of diastole.

现在，“DUB”音——澄清一下，我不是在说 dubStep 音——是主动脉和肺半月瓣在舒张期开始时关闭。

For example, anything that limits the blood flow to the kidneys, or the renal blood flow, can cause hypertension, as well as things like atherosclerosis, vasculitis, or aortic dissection.

例如，任何阻止血流经过肾脏或者限制肾血流量因素，都可以导致高血压以及斑块粥样硬化、血管炎、主动脉夹层。

As for diagnosis, a person is diagnosed with Marfan syndrome if they have clinical features of Marfan syndrome like aortic disease, a dislocated lens, family history, and FBN1 mutations.

在诊断方面，要确诊马方综合征可通过以下方法：患者有明显马方综合征临床特征，比如主动脉疾病、晶状体脱垂、家族史以及FBN1基因突变。

Concentric hypertrophy leading to diastolic failure can also be caused by aortic stenosis, which is a narrowing of the aortic valve opening, as well by hypertrophic cardiomyopathy, an abnormal ventricular wall thickening often from a genetic cause.

导致舒张性心衰向心性肥大，也可能由主动脉瓣狭窄（即主动脉瓣开口变窄）造成，也可能由肥厚型心肌病（一种遗传性异常心室壁增厚）引起。

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，而非危险性更高开胸手术。

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，肺动脉关闭声，略晚于主动脉关闭声，这被称作S2生理性分裂。

There are also plenty of other unidentified genes on the X chromosome, so individuals with Turner syndrome are predisposed to cardiovascular defects like preductal coarctation of the aorta and bicuspid aortic valve.

X染色体上还有很多其它未被识别基因，所以特纳综合征患者容易出现心血管缺陷疾病，如导管前型主动脉缩窄、二叶式主动脉瓣畸形。

If it's a simple... if it's a simple thing like what's the differential for aortic stenosis, i. e. injection systolic murmur, there's just four points here.

如果这是一个简单...如果这是一个简单内容，比如主动脉狭窄鉴别诊断，即注射收缩期杂音，这里只有四个要点。

The second heart sound, " dub" , is called S2, and the noise comes from the aortic and pulmonic valves snapping shut to prevent blood from flowing backwards after it leaves the ventricles, effectively ending systole.

第二心音“dub”，它被称为S2，声音来自主动脉瓣和肺动脉瓣关闭，以防止血液在离开心室后反流，有效地结束心脏收缩。

With her aortic injuries, her chances of survival are extremely slim no matter what we do.

不管我们怎么做，她大动脉伤使她生还几率比较渺茫。

Coarctation of the aorta and a bicuspid aortic valve can cause lower extremity cyanosis, meaning a bluish or purplish discoloration of the lower limbs, and can result in congestive heart failure.

主动脉缩窄和二叶式主动脉瓣畸形会导致下肢紫绀，意味着下肢呈青紫色，并可导致充血性心力衰竭。

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

心脏左侧最高点应为主动脉弓，下面是肺动脉。

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

这个声音可以在主动脉瓣和肺动脉瓣听诊区被清晰地听到。
