摘　　要：目的　探讨彩色多普勒超声心动图诊断老年性主动脉瓣钙化的声像图特点及价值。方法　对 10 7例彩超检出的老年性主动脉瓣钙化进行二维及多普勒血流分析。结果　退行性变主要发生在 5 0岁以上人群 (99.1% ) ,并随年龄增大发病率升高 (10 .2～ 35 .0 % ) ;男女发病无显著差异 (P >0 .0 5 ) ;右冠瓣、无冠瓣钙化较左冠瓣多见 (P <0 .0 1) ;瓣膜钙化增厚引起的关闭不全明显多于狭窄 (P <0 .0 1) ;高血压患者较其他心血管疾病患者更容易发生主动脉瓣钙化。Objective To study the characteristics and the value of senil aortic valve calcification by using of color Doppler echocardiography.Method 107 cases of senil aortic valve calcification were studied by 2-D and CDFI.Results The aortic valve calcification most occurved in patients of over fifty (99.1%). The occurence rate increased with age (10.2～35.0%).There was no significant difference between sexes(P>0.05).The prevalence of degenerative aortic in both right coronary cusp and noncoronary cusp was more than that in left coronary cusp(P<0.01).The number of patients with aortic regurgitaiton was more than that with aortic valve stenosis caused by calcification (P<0.01).The aortic valve calcification occurred easily in patients with hypertension.Conclusion Color Doppler echocardiography is more useful in the diagnosis of senil aortic valve calcification.
