This study is aimed at comparing cardiac computed tomographic angiography (CTA) with echocardiography in the assessment of ventricular septal perforation diameter.
A total of 44 ventricular septal rupture (VSR) patients undertaking transcatheter occlusion were included and randomly divided into the CTA group and echocardiography group with a 1 : 1 ratio. Clinical data, operation-related data, and 30 d follow-up data were collected and analyzed.
Incidence of closure failure, occluder displacement, poor occluder molding, and occluder waist diameter shrinkage between the two groups were not statistically different. The mean residual shunt volume in the echocardiography group (4.2 (3.1, 5.9) mm) was significantly higher than that in the CTA group (2.1 (0, 4.0) mm) with a value of 0.005. However, no significant differences were found in all-cause mortality and incidence of operative complications within 30 days after surgery. Within the CTA group, the correlation was strongest between postoperative occluder diameter and long diameter measured by CTA with a correlation coefficient of 0.799 and < 0.001, followed by the correlation between postoperative occluder diameter and mean diameter measured by CTA with a correlation coefficient of 0.740 and < 0.001. The diameter measured by echocardiography was not correlated to postoperative occlude diameter.
Assessment of VSR diameter by cardiac CTA is more accurate than by echocardiography.
本研究旨在比较心脏计算机断层血管造影（CTA）与超声心动图在评估室间隔穿孔直径中的作用。
共纳入 44 例行介入封堵术的室间隔破裂（VSR）患者，采用 1∶1 随机分组方法分为 CTA 组和超声心动图组。收集并分析两组患者的临床资料、手术相关数据及 30 d 随访资料。
两组患者的封堵失败率、封堵器移位率、封堵器成型不良率及封堵器腰部直径缩小率比较，差异均无统计学意义（均 ）。超声心动图组的残余分流容积均值（4.2（3.1，5.9）mm）显著高于 CTA 组（2.1（0，4.0）mm），差异有统计学意义（ ＝0.005）。但两组患者术后 30 d 内的全因死亡率及手术并发症发生率比较，差异均无统计学意义（均 ）。在 CTA 组中，术后封堵器直径与 CTA 测量的长轴直径之间的相关性最强，相关系数为 0.799， ＜0.001，其次是术后封堵器直径与 CTA 测量的平均直径之间的相关性，相关系数为 0.740， ＜0.001。而超声心动图测量的直径与术后封堵器直径之间无相关性。
心脏 CTA 评估 VSR 直径比超声心动图更准确。
