Prenatal diagnosis of Berry syndrome by fetal echocardiography: A report of four cases.

Berry syndrome is a rare congenital cardiac malformation. We describe 4 cases of Berry syndrome diagnosed by fetal echocardiography. Based on our experience, the three-vessel view is important for diagnosing the aortopulmonary window and aortic origin of the right pulmonary artery. Furthermore, the true cross-sectional and sagittal views obtained by continuously scanning from the three-vessel-trachea view to the long-axis view of the aortic arch are required to image the interruption or coarctation of the aortic arch. An early and accurate prenatal diagnosis of Berry syndrome is feasible and helps to improve patient outcomes.
