主动脉瓣狭窄

Sometimes in older adults, a normal tricuspid aortic valve will undergo calcification, a so-called "senile calcific aortic stenosis."

有时，在老年人中正常的三个瓣叶的主动脉瓣也会发生钙化，被称为"老年性钙化的主动脉瓣狭窄"。

Methods and Results— Between March 2000 and October 2008, 70 fetuses underwent attempted aortic valvuloplasty for critical aortic stenosis with evolving hypoplastic left heart syndrome.

方法和结果－在2000年3月至2008年10月期间，给70名胎儿尝试行主动脉瓣成形术治疗伴有进展性左心发育不全综合征的严重主动脉瓣狭窄。

Conclusions— Technically successful aortic valvuloplasty alters left heart valvar growth in fetuses with aortic stenosis and evolving hypoplastic left heart syndrome and, in a subset of cases, appeared to contribute to a biventricular outcome after birth.

结论－主动脉瓣成形术技术上的成功改变了主动脉瓣狭窄及进展性左心发育不全综合征胎儿的左心瓣膜生长，在亚组病例中，似乎可造成生后双心室。

Which are this: my mother, who is not quite 85, has aortic stenosis, a narrowing of the heart's aortic valve, and her cardiologist has just told her that it's time now to think about open-heart surgery to replace the valve.

正是这一点：我的母亲，还不到85 岁，患有主动脉瓣狭窄，缩小心脏的主动脉瓣，她的心脏病就意味着，是时候做心内直视手术了以取代阀门。

We know from other studies that aortic stenosis even aortic sclerosis is a risk marker for cardiovascular disease.

我们从其它研究知道，主动脉瓣狭窄，甚至主动脉硬化，都是心血管疾病的风险指标。

Over the years, I have taken dozens and dozens of elderly patients with aortic stenosis through aortic valve surgery usually with very good outcomes.

多年来，在我这就诊的有很多主动脉瓣狭窄的老年患者，他们行主动脉瓣置换术后的结果也很好。

Clinical experience with the percutaneous heart valve for treatment of degenerative aortic stenosis.

经皮介入治疗主动脉瓣退行性变所致主动脉瓣狭窄的临床经验 2。

The causes of acrtic valve diseases in the three groups were analyzed. Results: Rheumatism was the most common reason, accounting for 59.7%(43 cases) of simple aortic stenosis, while bicuspid valves accounted for 23.6%(17 cases). The most common cause for aortic insufficiency was root dilation (38 patients, 43.2%).

结果：风湿性、二叶式主动脉瓣、主动脉根部扩张以及退行性主动脉瓣病变是主要的病因类型，其中单纯主动脉瓣狭窄以风湿性（43例，占59.7%）及二叶瓣17例(23.6%)病因为主，单纯主动脉瓣关闭不全以根部扩张（38例，占43.2%）为主，主动脉瓣狭窄合并关闭不全则以风湿性（70例，占88.5%）为主。

The characteristics and changes of etiology were analyzed. All cases with aortic diseases were divided into single aortic stenosis, single aortic insufficiency, and combined aortic stenosis plus insufficiency group.

分别以主动脉瓣狭窄、主动脉瓣关闭不全、主动脉瓣狭窄合并关闭不全3组分析，具体病因包括风湿性、二叶式主动脉、退行性主动脉瓣、主动脉根部扩张、感染性心内膜炎、少见及未确定等6类病因。

At that time, I was a legal secretary and oversaw the running of a law office.

那时，我是法律办公室的一名法律秘书，监督整个办公室的运作。

According to the research progress on citrinin, the strategies of citrinin control were described from the three aspects of fermentation technology, mutation breeding, and genetic engineering.
