Objective : We here by report the im mediate results of our first 50 attempts of Percutaneous Mitral Valvuloplasty (PMV) using Inoue balloon in Vietnam- The mean age was (35 ±15) years- The gender :44 females and 6 males- 40 were in sinus rhythm and 10 presented with atrialfibrillation- The mean total echo score was 6-7 ±3-5 and the majority was in functional class ( NYHA) Ⅲ/ Ⅳ(85 % )- Results :The procedure wastechnically successfulin 47 patients (94 % )- PMVresulted in significantimprovementin hemodynamic values :the mean left atrial pressure fellfrom (25 ±9) m m Hg to (12 ±5) m m Hg ( p doppler (0-75 ±0-3) cm 2to (1-55 ±0-4) cm2- There was one case with failure to crossthe mitral valve orifice with Inoue balloon- There were two tamponades- The first,in a patientto whom PMV was stopped- The patient underwentsuccessfulclosed heart comissurotomy right afterthe pericardial tamponade subsided and his general status stabilized- The second case also had pericardial effusion drained and reperfused ,and PMV was performed successfully in the catheterization laboratory when the tamponade had subsided and cardiovascular status normalized- We met one case with increasing MR post PMV(grade Ⅲ)- Transient cerebral event occurred in one patient who fully recovered 2 days later- Conclusion : The acute results ofthis series attest to the effectiveness and usefulness of PMV with Inoue balloon in Vietnam-

测绘地理信息 2016年第3期41卷 48-52页

作者：邹进贵裴氏坚贞肖扬宣 doan Van Chinh 武汉大学测绘学院湖北武汉430079 THUY loi University Hanoi Vietnam LE QUY doN Technical University Hanoi Vietnam

分析了大坝水平位移的视准线观测方法,简述季节性时间序列法和BP神经网络法在变形监测中的应用,并对和平水电站历史观测数据进行分析和预测。结果表明,两种方法都能较准确地描述大坝的变形趋势,为大坝的安全监控提供了参考。
