目的：探讨超声心动图评价常见左向右分流型先天性心脏病患者经导管封堵术后心脏结构、血流动力学和心功能的变化。方法：经胸超声心动图检查确诊患者304例。于术前、术后48h、1月、3月、6月及1年，采用经胸超声心动图（TT E）测定其心脏结构、血流动力学及心功能指标。结果：301例患者均成功封堵。与术前比较，心脏结构、血流动力学和心功能各项指标均明显改善，具有统计学意义。结论：介入封堵术不仅有效根治先天性解剖畸形，而且早期迅速纠正血流动力学异常，改善心腔几何构型和心功能。

Objective:To carry out the postoperative follow-up study after the transcatheter closure of the common left to right congenital heart diseases ;To observe the changes of the cardiac morphology 、cardiac hemody-namic and cardiac function by using Transthoracic Echocardiography (TTE) .Methods:304 cases of patients were brought into the whole group .To measure the indexes of the cardiac morphology 、the cardiac hemodynamic and the cardiac function by Transthoracic Echocardiography (TTE) in preoperative .Follow-up was performed in 48 hours、one month、three months、six months、one year after the transcatheter occlusion .Results :301 cases were successful-ly occluded .The indexes of the cardiac morphology ,the cardiac hemodynamic and the cardiac function improved sig-nificantly .Conclusion :Interventional therapy is not only effective cure congenital anatomical malformation ,quickly corrected early hemodynamic abnormalities ,cardiac geometry and improve heart function .
