彩色多普勒超声在老年退行性心脏瓣膜病诊断中的价值

目的：研究老年退行性心脏瓣膜病（Degenerati vevalvular heartdisease,DVHD）在彩色多普勒超声表现,研究彩色多普勒超声在DVHD中的价值。方法：采用彩色多普勒超声检查DVHD患者,分析其超声影像表现特点,比较不同年龄段DVHD发生率差异。结果：80例DVHD患者中有60例（75.0%）有心脏瓣膜功能障碍,其中主动脉瓣返流30例（50.0%）,主动脉瓣狭窄12例（20.0%）,主动脉瓣返流伴狭窄13例（21.7%）,二尖瓣返流伴狭窄8例（10.1%）;左室舒张功能障碍69例（86.3%）,包括舒张障碍41例（59.4%）,收缩功能障碍28例（40.6%）。不同年龄组DVHD患者发病部位中的差异无统计学意义（P〉0.05）。结论：彩色多普勒超声下DVHD影像表现典型,其发病部位与年龄无明显相关。

Value of Color Doppler Ultrasound in the Diagnosis of Degenerative Valvular Heart Disease

Objective： To study Color Doppler ultrasound＇ s value in the diagnosis of Degenerative valvular heart disease （ DVHD ） . Method： Patients with DVHD were chosen for Color Doppler ttltrasound examination. The images were analyzed and differences in different ages were compared. Result： 60 （ 75.0% ） in the 80 DVHD patients showed heart valve dysfunction： 30 cases with aortic regurgitation in （ 50.0% ）, 12 （ 20.0% ） with aortic stenosis, 13 （ 21.7% ） with aortic regurgitation with stenosis, 8 cases with mitral regurgitation with stenosis （ 10.1% ） ; 69 patients with Left ventrieular diastolic dysfunction （ 86.3% ）, including the diastolic obstacles （ 59.4% ） and systolic dysfimction （ 40.6% ）. The differences of DVHD locations in different ages showed no signitleances （ P〉O.05 ）. Conclusion： Theimages ofDVHDin Color Doppler ultrasound are typical, itslocations don＇ t correlate with ages.
