| 【】目的：二维超声心动图对主动脉瓣人工瓣膜置换术后室间隔运动异常的超声研究。方法：利用二维超声心动图对58例主动脉瓣重度狭窄患者及16例主动脉瓣重度关闭不全患者行超声心动图检查,测量术前及术后7天左室射血分数、左室心搏量、每分输出量、室间隔运动幅度、室间隔增厚率。结果：主动脉瓣狭窄和主动脉瓣关闭不全患者术后左室EF值降低,差异无统计学意义；左室心搏量(SV)及每分输出量(CO)升高,差异有统计学意义；室间隔运动幅度减低,差异有统计学意义；室间隔增厚率未见明显差异。结论：二维超声心动图能很好的评价主动脉瓣人工瓣膜置换术后室间隔运动异常及其对左室整体收缩功能的影响。 |

| Abstract: |
| Objective:To study the paradoxical septal movement after aortic valve replacement by two-dimensional echocardiography. Methods:58 patients with aortic valve stenosis and 16 cases of patients with aortic valve incomplete closure were enrolled in this study. Using two-dimensional echocardiography to measure left ventricular ejection fraction, left ventricular stroke volume, per minute output, paradoxical septal motion, ventricular septal thickening rate in preoperative and postoperative 7 days. Results:The left ventricular ejection fraction was reduced in the patients with aortic valve stenosis and aortic valve incomplete closure, the difference was not statistically significant.The left ventricular stroke volume and per minute output increased, and the difference was statistically significant. The range of ventricular septal motion was decreased, and the difference was statistically significant. There was no significant difference in interventricular septal thickening rate. Conclusions: Two - dimensional echocardiography can be used to evaluate paradoxical septal motion after aortic valve replacement.The effect of paradoxical septal motion on the overall contractile function of left ventricle. |
