摘要
目的探讨老年人退行性心脏瓣膜病的超声心动图特点。方法采用美国HP5500及飞凡彩色多普勒超声诊断仪,观察166例老年退行性心脏瓣膜病患者的心脏结构及心功能变化。结果单纯主动脉瓣膜钙化者93例(56.0%),单纯二尖瓣钙化18例(10.8%),主动脉瓣和二尖瓣联合钙化为55例(33.1%);左房扩大116例(69.9%),左心室舒张功能减退142例(85.5%);136例导致心脏瓣膜功能障碍,其中主动脉瓣返流70例,占42.2%,主动脉瓣狭窄23例,占13.9%,二尖瓣返流20例,占12.0%,二尖瓣狭窄8例,占4.8%,主动脉瓣返流+主动脉瓣狭窄10例,占6.0%,二尖瓣返流+二尖瓣狭窄5例,占3.0%。瓣膜功能障碍检出率最高为主动脉关闭不全(42.2%),其次为主动脉瓣狭窄(13.9%),发病率最低为二尖瓣狭窄伴关闭不全(3.0%)。结论老年人退行性心脏瓣膜病缺乏特异的临床表现,随着年龄的增加,联合瓣膜钙化比例增加,瓣膜功能障碍中主动脉瓣关闭不全比例最高,左房扩大的比例也增加。
Objective To evaluate the characteristics of eehocardiogram in senile degenerative heart valvular disease. Methods The cardiac structure and functional changes of the 166 cases of senile degenerative heart valvular diseases were studed with HP5500 （USA） and En Visor color doppler（Philips）. Results Simple aortic valve calcification was found in 93 cases（56.0%）; simple mitral calcification, 18 cases （10.8%） ; aortic valve calcification combining mitral calcification, 55 cases, （33.1%） ;enlarged left atrium 116 cases（ 69.9% ） ;left ventricular diastolic dysfunction 142 cases （85.5%）. Within 136 cases of cardiac valve dysfunction, there was aortic valvular regurgitation in 70 cases（42.2%）, stenosis of aortic valve in 23 cases（ 13.9% ）, mitral regurgitation in 20 cases（ 12.2% ）, mitral stenosis in 8 cases（4.8%）, aortic valvular regurgitation combining stenosis in 10 cases（6.0%）, mitral regurgitation combining stenosis in 5 cases （3.0%）. The highest morbidity in valvular dysfunction was aortic valvular regurgitation（42.2%）, the second was aortic valve stenosis （ 13.9% ）, the lowest morbidity was mitral stenosis combining insufficiency（3.0%）. Enlarged left atrium was in 116 cases（69.9%）. Conclusions The senile degenerative heart valvular disease have no specific clinical manifestation. With increasing age,the proportion of complex valve calcification is increased, and the highest is the aortic insufficiency in valvular dysfunction. The proportion of enlarged left atrium is also increased.
