Dear Editor,
We read with great interest the recent case report by Apollos et al. (2025) describing a rare type 1 truncus arteriosus with an unusual origin of the main pulmonary artery. We would like to commend the authors for highlighting the diagnostic challenges and emphasizing the role of multimodal imaging in such complex congenital heart anomalies.
Our group previously reported the ‘Prenatal diagnosis of truncus arteriosus with left isomerism using 3-dimensional sonography’ (Seker et al., 2022). We agree that early and accurate imaging—whether by fetal 3D/4D ultrasonography, echocardiography, or CT angiography—is crucial for perinatal counseling and surgical planning.
The Nigerian case illustrates the importance of comprehensive imaging even in resource-limited settings. We would like to underscore that **fetal 3D ultrasonography can visualize the common arterial trunk and pulmonary branching patterns in utero**, facilitating earlier parental counseling and multidisciplinary management.
We congratulate the authors on their valuable contribution, and hope that sharing complementary prenatal imaging experiences will encourage broader adoption of advanced sonographic techniques for earlier detection of truncus arteriosus worldwide.
