心脏瓣膜返流762例的病因分析

The pathogeny analysis to 762 cardiac valve regurgitation cases

目的探讨二尖瓣及主动脉瓣瓣膜返流的病因分类。方法利用彩色Doppler超声心动图观察心脏瓣膜的返流情况,在心尖四腔及五腔切面上用连续多普勒记录返流频谱,测量最大流速。结果主动脉瓣返流中主动脉瓣钙化占第一位(56.9%),二尖瓣返流中二尖瓣结构正常者占第一位(63.0%)。结论任何引起二尖瓣器质损害的疾病都能导致二尖瓣返流,主动脉瓣返流原因主要为瓣膜退行性变。

Objective To research the pathogeny of mitral and aortic regurgitation. Methods Ultilize color doppler echocardiogram to observe cardiac valve regurgitation,and measure the max velocity of flow. Results The aortic valve calcification was the first position in aortic regurgitation （56.9%）. Mitral structure normalcy was the first position in mitral regurgitation （63.0%）.Conclusion Any disease which arose the mitral structure harm will lead to the mitral regurgitation.The main pathogeny of aortic regurgitation is the valve degeneration＇s changing.
