Aortic Valve Stenosis
主动脉瓣狭窄
Aortic stenosis
主动脉狭窄
This is a narrowing of the heart's aortic valve, that's the valve that opens to the aorta, the main vessel that carries blood from the heart to the body. With stenosis, the valve doesn't fully open, that makes it hard for your heart to pump enough blood out to your body.
这是指心脏主动脉瓣变窄，主动脉瓣是通向主动脉的瓣膜，而主动脉是将血液从心脏输送到身体的主要血管。主动脉瓣狭窄时，瓣膜不能完全打开，导致心脏很难将足够的血液泵送到身体。
In some people, aortic stenosis is present at birth. A healthy aortic valve has three flaps, called cusps, but you may be born with a valve that only has one or two cusps that can keep it from opening fully.
有些人出生时即患主动脉瓣狭窄。健康的主动脉瓣有三个瓣叶，或瓣尖，但有些人的主动脉瓣先天只有 1 或 2 个瓣尖，所以不能完全打开。
Aortic stenosis can also develop over time. Calcium in your blood can build up on the valve. Scar tissue can form on the valve as a result of disease. These can interfere with its function.
主动脉瓣狭窄也会后天获得。血钙在瓣膜上积聚。病变导致瓣膜上形成疤痕组织。这都会损害主动脉瓣的功能。
You can have aortic stenosis and not realize it. It can cause a heart murmur, so your doctor may discover it by listening to your heart.
患者可能不会发现自己患病。主动脉瓣狭窄会导致心脏杂音，所以医生通过心脏听诊来诊断。
It can also cause symptoms. In infants and in children, it can cause them to tire easily. They may feed poorly and fail to gain weight, and they may have breathing problems.
它也会引起一些症状。婴幼儿患者可能很容易困倦，他（她）们可能喂养不良，体重未增加，也可能出现呼吸问题。
In older people, it can cause pain in the chest, neck, and jaw. It can make you feel tired, weak, dizzy, and faint when you exercise. Your heart may beat quickly and you may find it hard to catch your breath when you are active. You may cough.
老年患者可能出现胸部、颈部和下颌疼痛；运动时可能产生疲惫感、虚弱、眩晕或昏厥。患者的心脏跳动非常快，活动时可能呼吸困难。患者也可能会咳嗽。
Treatment depends on the severity of your stenosis.
治疗方法取决于狭窄的严重程度。
You may be able to manage it with regular checkups, medications, and by limiting strenuous activity. If your stenosis is severe, you may need a catheter procedure, or surgery to repair or replace the valve.
患者能够通过定期检查、药物治疗，以及限制剧烈活动来管理疾病。如果是重度狭窄，则需要经导管手术，或瓣膜修复或置换术治疗。
Your healthcare provider can create a plan that is right for you.
医务人员将为患者制定合适的治疗方案。
