1·The pathology of aortic valve was bicuspid valve (19 cases, 59%).
主动脉瓣病变主要是先天性二瓣化畸形（ 19例，5 9% ）。
2·From the left atrium the blood passes through the bicuspid valve into the left ventricle.
来自左心房的血液通过二尖瓣进入右心室。
3·From the left atrium the blood passes through the bicuspid valve into the right ventricle.
来自左心房的血液通过二尖瓣进入右心室。
4·Valvar stenosis is most frequently associated with a bicuspid valve or other cardiovascular malformation.
瓣膜狭窄多为二瓣叶畸形且常合并其他心血管畸形。
5·The main valve pathological changes were pure aorta petal diseases (54.2%), followed by combined diseases of bicuspid valve and aorta petal (33.1%).
瓣膜病变部位以单纯主动脉瓣最多（54.2%），其次为二尖瓣和主动脉瓣联合病变（33.1%）；
6·An aortic valve need not be bicuspid to calcify.
主动脉瓣并非是两个瓣叶的才钙化。
7·Should the ascending aorta be replaced more frequently in patients with bicuspid aortic valve disease?
对二叶式主动脉瓣疾病的患者通常应该进行升主动脉置换吗？
