“…5 The prevalence of complex intra-and extra-cardiac malformations was 51.8% and 27.8%, respectively, in a large proportion of fetuses in this study, and only 20.4% of the fetuses were isolated CAT. In comparison, the incidence of CAT complicated with intra-cardiac malformations was higher (54.55%), and the incidence of extra-cardiac malformations was consistent with that reported by Gomez et al 6 However, Abel et al reported a high incidence of extra-cardiac malformations of 58.8%. 7 This difference may be due to the fact that most of this study was performed on the fetal heart and ignored the extra-cardiac structural malformations.…”

“…10 Previous studies have shown that fetal echocardiography and 4D-STIC imaging can be used to improve the differential diagnosis of CAT. 6,11 However, we retrospectively analyzed 88 cases of 4D-STIC echocardiography, and obtained a different plane from the traditional two-dimensional echocardiography. 12 The anatomical structure of CAT and pulmonary artery can be evaluated sterically and intuitively by STIC imaging, which is of great value in determining the CAT classification and differential diagnosis.…”

ObjectivesTo investigate the clinical value of prenatal ultrasound in the diagnosis of the common arterial trunk (CAT) classification and associated malformations.Materials and MethodsThe 2D ultrasound images, spatiotemporal image correlations (STICs) and clinical data of 88 fetuses diagnosed with CAT malformations by prenatal ultrasound were retrospectively analyzed and classified. The correlation between different types, fetal malformation and pregnancy outcomes were analyzed.ResultsAmong the 88 fetuses, there were 39 cases (44.32%) of type A1, 40 cases (45.45%) of type A2, 8 cases (9.09%) of type A3, and 1 case of type A4 (1.14%). There were 16 cases (18.18%) with isolated CAT, 48 cases (54.55%) with complex intra‐cardiac structural abnormalities, and 24 cases (27.27%) with intra‐cardiac and extra‐cardiac structural abnormalities. In extra‐cardiac structural malformations, 14 cases were associated with 1 other system abnormality, 4 cases with 2 other system abnormalities, 3 cases with 3 other system abnormalities, while 3 cases were combined with 4 other system abnormalities, among which the facial and physical abnormalities had the highest incidence (39.13%). The STIC images were completely displayed in all 88 cases. There was a statistical difference between isolated CAT and CAT combined with other abnormalities in fetal pregnancy outcomes.ConclusionsPrenatal ultrasound had a high clinical application value in CAT classification. Pregnancy outcomes were highly correlated with the classification and associated intra‐cardiac and extra‐cardiac structural malformations. The early evaluation of fetal prognosis before birth has important value for clinical intervention.
