目的评价经胸超声心动图(TTE)指导硬缘房间隔缺损(ASD)封堵术的可行性和作用。方法298例硬缘ASD患者,术前用彩色多普勒超声心动图结合组织谐波功能经胸测量各切面ASD大小及周缘情况,ASD封堵术中TTE监测封堵过程、封堵器的牢固性,彩色多普勒观察有无残余分流。封堵器释放后测量其腰部大小,并与术前TTE测量的ASD最大径进行比较。结果用TTE术前检查ASD最大径3~40 mm[平均(20.0±8.5)mm],选用的封堵器6~46 mm[平均(24.9±9.4)mm],释放后封堵器腰径3~40 mm[平均(20.5±8.6)mm]。TTE测量的ASD大小与封堵器大小相关良好(Y=1.11X+2.67,r=0.98,P<0.0001)。TTE测量的ASD大小与释放后封堵器腰径相关关系极佳(Y=0.99X+0.24,r=0.99,P<0.0001)。所有患者ASD封堵器固定牢固,无脱落。结论TTE结合组织谐波功能可以准确测量硬缘ASD大小,是指导ASD封堵的可行、有效、简便方法。
Objective To evaluate the feasibility and effect of transthoracic echocardiography (TTE) in guiding the closure of aortic septal defect (ASD). Methods A total of 298 patients with ASD were enrolled in this study. Color Doppler echocardiography combined with tissue harmonic function was used to measure ASD size and perimeter of each section transthoracic surgery before operation. TTE in ASD occlusion was used to monitor the occlusion process and the occluder was firm Sexual, color Doppler observation of residual shunt. The size of the lumbar spine was measured after release of the occluder and compared with the maximum ASD diameter measured by preoperative TTE. Results The maximum diameter of ASD was 3 ~ 40 mm [mean (20.0 ± 8.5) mm], and the mean occluder diameter was 6 ~ 46 mm [mean (24.9 ± 9.4) mm] ~ 40 mm [mean (20.5 ± 8.6) mm]. The ASD size measured by TTE correlated well with occluder size (Y = 1.11X + 2.67, r = 0.98, P <0.0001). The ASD size measured by TTE correlated well with the occlusal waistline after release (Y = 0.99X + 0.24, r = 0.99, P <0.0001). All patients with ASD occluder firmly fixed, no shedding. Conclusions TTE combined with tissue harmonic function can accurately measure the size of ASD in the hard segment, which is a feasible, effective and convenient method to guide the ASD occlusion.
