摘要
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天相比无显著性变化,左心室舒张期末容积和左心室舒张期末内径显著缩小,左心室短轴缩短率、射血分数及每分钟输出量均正常。结论:自体心包瓣瓣膜置换术后2年,心包瓣结构与功能状态良好。彩色超声心动图对该手术效果的评判有实用价值。
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.
