摘要
目的:应用实时三维超声心动图(Real-time three-dimensional echocardiography,RT-3DE)探讨外科修补手术与内科介入封堵手术对先天性心脏病室间隔缺损(CHD-VSD)患者左室功能的影响,并探讨RT-3DE评价左室功能变化的准确性。方法:65例CHD-VSD患者分为内科介入封堵组30例和外科修补组35例,正常组30例为健康志愿者,应用RT-3DE及M型超声心动图分别测量CHD-VSD患者及正常组的左室心功能参数,并对测量参数进行统计分析。结果:术前两组CHD-VSD患者各参数均增大,术后左室心功能参数除左室射血分数外,余参数均相应减小,差异有统计学意义(均P<0.05),并且RT-3DE测量左室容积与M型超声相关性良好,但前者较后者测值稍偏小。结论:CHD-VSD患者术前容积增大,左室功能稍降低,术后内科介入封堵组各参数值接近正常值,而外科修补组虽较术前改善,仍稍降低;RT-3DE可准确测量左室容积及心功能,为临床诊疗方案提供依据。
Objective:To evaluate left ventricular function before and after operation in ventricular sepal de- fect (VSD) patients using real-time three-dimensional echocardiography (RT-3DE), and assess the veracity of left ventricular function by RT-3DE. Methods: Sixty-five patients with VSD and 30 healthy volunteers were involved, RT-3DE and M-mode echocardiography were used to measure the left ventricular function parameters, and the results were analyzed statistically. Results: All preoperative parameters increase in two groups of patients with VSD. The postoperative left ventricular function parameters in patients with VSD were correspondingly reduced ( P 〈0.05 for all) except ejection fraction. RT-3DE had a good correla- tion with M-mode echocardiography in measurements of left ventricular volume, but the former is smaller than the later one. Conclusion: Preoperative volume increased in patients with VSD, and left ventricular function slightly reduced, the parameters in intervention group are close to normal. Although the parame- ters in surgical repair group were also improved as compared with those before operation, they were still slightly low. RT-3DE can accurately measure left ventricular volume and cardiac function, and provide the basis for clinical treatment programs.
