Amaç

We aimed to evaluate the correlation between clinical parameters and the post-LA space index, which is a candidate screening marker for total anomalous pulmonary venous connection (TAPVC). We also calculated inter- and intra-observer variability of measurements for this parameter.

Yöntem

The left atrium–descending aorta distance/ descending aorta diameter ratios (post-LA space index) were obtained from 165 fetuses between 20–24 weeks of gestation. Regression analyses were utilized to evaluate the correlations across clinical parameters and the post-LA space index. Intraclass correlations coefficients were calculated for intra- and inter-observer agreements of three examiners with different sonographic experience.

Bulgular

The mean (±SD) maternal and gestational age was 28.6±4.9 y and 21.7±0.9 wk, respectively. In multivariate analyses, there was no correlation between post-LA space index and maternal age, fetal gender, or gestational age at cardiac scan. There were moderate to strong correlations across the measurements by different examiners, indicating good inter- and intra-observer agreement.

Sonuç

The post-LA space index is a simple and reliable marker that is not affected by gestational age in the late second trimester. Its potential as a screening tool for TAPVC warrants further clinical investigation.
