What is aortic valve stenosis?

主动脉瓣狭窄是最常见和最严重的瓣膜疾病之一. 主动脉瓣狭窄是指主动脉瓣开口变窄，有时也被称为心脏瓣膜衰竭. 主动脉瓣狭窄限制了血液从左心室流向 aorta 也会影响左心房的压力吗.

虽然有些人有主动脉狭窄，因为先天性心脏缺陷称为二尖瓣主动脉瓣, 这种情况在衰老过程中更常见，因为钙或疤痕会损害瓣膜，限制血液流动.

Does aortic stenosis always produce symptoms?

No. Many people with aortic stenosis, or AS, 在受限的血流量大大减少之前，不要出现明显的症状.

Symptoms of aortic stenosis may include:

Chest pain
Rapid, fluttering heartbeat
Trouble breathing or feeling short of breath
Feeling dizzy or light-headed, even fainting
Difficulty walking short distances
活动水平下降或正常活动能力下降

重要的是要注意，患有阿斯伯格综合症的人可能不会抱怨 symptoms. However, 如果你或你的家人注意到日常体育活动减少或明显疲劳, 你应该去看一下你的保健专家，检查一下心脏功能是否减退. Use our AS symptom tracker (PDF) to record your symptoms and frequency, 下次预约时带着它去看医生.

Infants and children who have aortic stenosis due to a congenital defect may exhibit symptoms such as:

Fatigue upon exertion
Failure to gain weight
Poor or inadequate feeding
Breathing problems

主动脉瓣狭窄是如何进展或引起越来越多的问题的?

除了主动脉狭窄的症状, which may cause a patient to feel faint, weak or lethargic, 左心室壁也可能表现出肌肉增厚，因为心室必须更加努力地将血液通过狭窄的瓣膜口泵入主动脉.

增厚的心壁会占用下心室更多的空间，从而使足够的血液供应到身体的空间变少. This may lead to heart failure. 适当的治疗可以帮助逆转或减缓这种疾病的进展.

Causes of aortic stenosis

主动脉瓣狭窄主要影响老年人，原因是瓣尖(瓣瓣或折瓣)的疤痕和钙积聚。. 与年龄相关的AS通常开始于60岁以后，但通常直到70或80岁才出现症状.

它也可能是由儿童时期患风湿热引起的.

Aortic stenosis in the young

二尖瓣主动脉瓣是一种先天缺陷，只有两个尖瓣生长，而不是正常的三个. This can lead to aortic stenosis.

另一个原因可能是瓣膜开口没有随着心脏的增长而增长. 这使得心脏更难将血液泵到受限的开口. 多年来，由于钙的积累，有缺陷的瓣膜经常变得僵硬和狭窄.

bicuspid valves may restrict blood flow

对于主动脉瓣狭窄的患者，建议采取哪些治疗方法?

如果没有症状或症状很轻微, 最好的做法是定期随访和监测，看看是否有任何症状发展或恶化.

However, 任何有主动脉瓣狭窄的人都应该用超声心动图检查以确定治疗方案.

Possible treatments may include medications, valve repair or valve replacement. It’s important to discuss options with your health care team 以确保你得到最有效的治疗.
