彩色超声心动图对自体心包瓣置换主动脉瓣手术效果的评价

目的：评价自体心包瓣置换主动脉瓣的手术效果。方法：应用ＨＰ－１０００型彩色多普勒心动图仪于术后第１０天至２年对９例施行自体心包瓣置换主动脉瓣患者自体心包瓣的厚度、活动度、开瓣幅度、瓣口面积、瓣口返流量、跨瓣压差及左心室 功能进行动态测量和分析。结果：术后第１０天患者上述各项指标与正常人已无显著性差异。术后２年随访,自体心包瓣的厚度、活动度、开瓣幅度、瓣口面积、瓣口返流量、跨瓣压差与术后第１０天相比

Echocardiography in the therapeutic evaluation of aortic valve replacement with autologous pericardial valve

Objective: To evaluate the surgical results of aortic valve replacement with autologous pericardial valve. Methods: Nine patients underwent aortic valve replacement with autologous pericardial valve were studied by color Dopplor echocardiography (HP 1000 type). The mobility, thickness, opening amplitude, valve orifice areas, regurgitant stroke volume and transorifice pressure gradient of the autologous pericardial valves were measured and analysed intraoperatively and postoperatively. Results: 10 days postoperation, there was no significant difference in above mentioned indices between patients and normal group. Two years after operation, the mobility, thickness, opening amplitude, valve orifice areas, regurgitant stroke volume and transorifice pressure gradient of the autologous pericardial valves showed no significant changes, the EDV and LVEDD significant reduced as compared with 10 days postoperatively. Conclusion: Two years after operation, the structure and function of the autologous pericardial valve may maintain good condition.
