选取老年退行性心脏瓣膜病的患者58名,使用彩色多普勒超声诊断仪,对其心脏瓣膜的形态结构、厚度、回声及活动度进行观察,并应用彩色、脉冲或连续多普勒测量瓣口的流速和压差。结果显示,瓣膜钙化以主动脉瓣钙化(34例,占58.6%)和二尖瓣钙化(25例,占43.11%)的发生率为最高;瓣膜关闭不全为老年性心脏瓣膜退行性病变的主要表现,较少见的是瓣膜的狭窄。老年退行性心脏瓣膜病的明显特征是心脏结构改变。
Fifty-eight patients with senile degenerative valvular heart disease were selected. The morphological structure, thickness, echogenicity and activity of the heart valve were observed by color Doppler sonography. Color, pulsed or continuous Doppler flow measurement Mouth of the flow rate and pressure. The results showed that the prevalence of valvular calcification with aortic valve calcification (34 cases, 58.6%) and mitral calcification (25 cases, 43.11%) was the highest; valvular insufficiency was the major cause of senile valvular degeneration Performance, less common is the stenosis of the valve. A significant feature of senile degenerative heart valve disease is structural changes in the heart.
