查询词典 bicuspid valve

objective to study the characteristics of the transthoracic echocardiography of the bicuspid aortic valve and the diagnostic value.

目的：探讨先天性二叶式主动脉瓣畸形的超声心动图表现及各年龄段瓣膜病变程度。

Sixteen of the 30 patients were diagnosed as bicuspid aortic valve. The ascending aortic media were histologically abnormal in 23 patients.

在本组30例患者中16例为先天性主动脉二瓣化畸形，23例主动脉瘤壁病理结果显示主动脉壁弹力纤维断裂（6例）、稀少（1例）和中、重度黏液性变（16例）。

Background— Bicuspid aortic valve is a heritable condition that has been linked by an unknown mechanism to a predisposition for ascending aortic aneurysm.

背景—二叶式主动脉瓣是一个易患升主动脉瘤的可遗传疾病，与升主动脉瘤连锁的机制还不清除。

The anatomic subtype included type A 18 (85.7%),type B 3 (14.3%),and no type C in the records.All cases were associated with large PDA and VSD,some also with ASD,bicuspid or unicuspid aortic valve,and subvalvular aortic stenosis.

所有病例均合并粗大动脉导管未闭及大型室间隔缺损，其它伴发畸形包括继发孔房间隔缺损、主动脉瓣单瓣或两瓣畸形、主动脉瓣下狭窄。

A thorough family history should be taken because many cardiac disorders( eg, coronary artery disease, systemic hypertension, bicuspid aortic valve, hypertrophic cardiomyopathy, mitral valve prolapse) have a heritable basis.

很多心脏疾病冠状动脉疾病(AD全身性高血压、叶主动脉瓣疾病、厚型心肌病、尖瓣脱垂有遗传基础，因此应收集详尽的家族病史。

An aortic valve need not be bicuspid to calcify.

主动脉瓣并非是两个瓣叶的才钙化。

The most valuable role that CMR plays in patients with valvular heart disease is in determination of left and right ventricular function with a lesser role for precise identification of valve anatomy such as identification of bicuspid aortic valves, vegetations, etc.

CMR在瓣膜性心脏病患者中发挥的最有价值的作用就是测定左，右心室功能，较有价值的作用就是精确鉴定瓣膜的解剖，如二叶主动脉瓣、赘生物等。

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。
