目的:评估经胸超声心动图(TTE)和心脏CT血管造影(CTA)检测婴儿室间隔缺损(VSD)的大小和位置的准确性。
方法:对2020年1月至2022年12月诊断为VSD的258例婴儿的数据进行回顾性分析。所有婴儿均接受TTE和心脏CTA。通过将这些成像方式的发现与术中对VSD大小和位置的观察结果进行比较来评估这些成像方式的准确性。
结果:术中,平均VSD大小为6.1±2.5mm。在45例患者中,缺陷被归类为承诺的VSD(1型),198例患者未发生室间隔缺损(2型),12例患者的入口VSD(3型),3例患者的肌肉VSD(4型)。超声心动图估计平均VSD大小为5.6±2.7mm,42名患者被确定为1型,203名患者为2型,10名患者为3型,3名患者为4型。心脏CTA估计平均尺寸为5.9±3.2mm,48例患者为1型,196例为2型,11例为3型,3例为4型。TTE和心脏CTA诊断VSD定位的准确率分别为98.1%和98.8%,分别。对外科医生的调查表明,80%的人认为TTE和心脏CTA都是必要的术前评估。
结论:TTE准确诊断VSD的大小和位置,而心脏CTA是TTE的一种有价值的补充方法。大多数外科医生主张联合使用这些检查进行术前评估。
To evaluate the accuracy of transthoracic echocardiography (TTE) and cardiac computed tomography angiography (CTA) in detecting the size and location of ventricular septal defects (
VSD) in infants.
Data from 258 infants diagnosed with
VSD between January 2020 and December 2022 were retrospectively analyzed. All infants underwent both TTE and cardiac CTA. The accuracy of these imaging modalities was assessed by comparing their findings with intraoperative observations of VSD size and location.
Intraoperatively, the average
VSD size was 6.1 ± 2.5 mm. The defects were classified as committed
VSD (Type 1) in 45 patients, noncommitted
VSD (Type 2) in 198 patients, inlet
VSD (Type 3) in 12 patients, and muscular
VSD (Type 4) in 3 patients. Echocardiography estimated the average VSD size at 5.6 ± 2.7 mm, with 42 patients identified as Type 1, 203 as Type 2, 10 as Type 3, and 3 as Type 4. Cardiac CTA estimated the average size at 5.9 ± 3.2 mm, with 48 patients identified as Type 1, 196 as Type 2, 11 as Type 3, and 3 as Type 4. The accuracy rates of TTE and cardiac CTA in diagnosing VSD location were 98.1% and 98.8%, respectively. A survey of surgeons indicated that 80% believe both TTE and cardiac CTA are essential preoperative evaluations.
TTE accurately diagnoses the size and location of VSD, while cardiac CTA serves as a valuable complementary method to TTE. Most surgeons advocate for the combined use of these examinations for preoperative assessment.
