Prenatal Ultrasound and Cardiac Assessment in a Newborn with Congenital Heart Defects

This case study details the prenatal diagnosis and management of a fetus with congenital heart defects. A comprehensive ultrasound was conducted at 25 weeks of gestation, followed by a heart CT scan before the delivery of a baby boy weighing 2780g. The infant was delivered vaginally at 38 weeks and required admission to the neonatal intensive care unit for echocardiography and cardiac surgery. The findings included abnormal vessels and collateral circulation assessed via Doppler and CT imaging. Key questions address sonographic abnormalities, diagnosis, and details of collateral vessels.
