评价经胸超声心动图(TTE)术前测量房间隔缺损(ASD)大小、术中监测ASD封堵及术后随访疗效的价值。用TTE术前检查ASD大小8～33(25.2±6.6)mm,选用ASD封堵器大小为12～38(28.4±7.02)mm。超声测量ASD大小与封堵器大小相关良好(r=0.9,P<0.001)。硬缘ASD的封堵器选择比超声所测ASD大1～6mm。软缘ASD通常不考虑摆动较大部分为有效缘而予以去除,封堵器选择比超声所测ASD大7～13mm不等。所有封堵器封堵牢固,无脱落。结果表明,经胸彩色多普勒超声引导经右心导管房间隔缺损封堵术准确性高,方法简便,无痛苦,值得推广。
To evaluate the value of preoperative transthoracic echocardiography (TTE) measurement of atrial septal defect (ASD), intraoperative monitoring of ASD occlusion and postoperative follow-up efficacy. The ASD size was 8 ~ 33 (25.2 ± 6.6) mm preoperatively with TTE and 12 ~ 38 (28.4 ± 7.02) mm with ASD occluder. Ultrasound measurements of ASD size correlate well with occluder size (r = 0.9, P <0.001). The choice of occluder for hard ASD is 1 ~ 6mm larger than the ASD measured by ultrasound. Soft edge ASD usually do not consider the greater part of the swing for the effective edge and be removed, the occluder selection than the ASD measured by ultrasound 7 ~ 13mm range. All occluder tightly closed, no shedding. The results show that transthoracic color Doppler ultrasound guided right atrial catheter atrial septal defect occlusion accuracy is high, the method is simple, no pain, it is worth promoting.
