经胸彩超对先心病介入封堵术治疗的应用价值

目的：探讨经胸超声心动图对先心病房间隔缺损、室间隔缺损、动脉导管未闭介入封堵术治疗的应用价值。方法：对33例先心病患者（房间隔缺损16例、室间隔缺损8例、动脉导管未闭9例）经胸超声心动图检查，条件符合而行介入封堵术治疗，超声心动图在术前、术中、术后即刻及术后1个月、6个月进行诊断、监测、评价疗效和随访。结果：32例封堵成功，1例房间隔缺损封堵失败。封堵术成功患者术后即刻观察分流消失。术后复查封堵术疗效良好（其中14例合并肺动脉高压患者，肺动脉压力均有所改善；1例房间隔缺损合并肺动脉瓣狭窄患者，肺动脉瓣口跨瓣压差明显下降；术后1个月、6个月所有伴心室腔增大的患者，心室腔大小有所恢复；1例室间隔缺损患者术后一直存在主动脉瓣轻度返流）。结论：经胸超声心动图对先心病介入封堵术治疗的术前病例选择、术中监测引导、术后疗效评价等都具有十分重要的价值。

The practical value of transcatheter closure in the interventional treatment of congenital heart diseases under transthoracic echocardiographic guidance

Objective:To explore the practical value of transthoracic echocardiography (TTE) guiding transcatheter closure in the interventional treatment of congenital heart diseases including atrial septal defect (ASD), ventricular septal defect(VSD), patent ductus arteriosus (PDA). Methods: After transthoracic echocardiography, 33 patients with congenital heart diseases (in- cluding 16 cases of ASD, 8 cases of VSD, 9 cases of PDA) underwent Amplatzer occlusion operation. Echocardiography was used before, during, imm...
